How to Find and Cure Death Wobble Jeep XJ, ZJ, TJ, and more

[@deucyandme]

Thank you so much for the vid!! I just traded my Acura for a 2006 Wrangler X that definately has the death wobble. I got screwed bad on the deal. Took it to a mechanic and he said the WHOLE front end needs rebuilt...having a hard time accepting that. I think since I'm female all mechanics think I know nothing about vehicles. They are mistaken. I learn every day more and more and enjoy working on my own vehicles.

[@dannywilsher4165]

My DW story... I have a 93 Grand Cherokee. At around 30,000, it started the death wobble. I have a car lift and have done my own mechanic work all my life. So I figured I have this. Up it went and I did everything I have done to hundreds of vehicles for years to check all suspension and front drivetrain. Everything seemed tight and unworn. My wife's dad bought the Jeep new and passed shortly after. Her mother drove the jeep to the store and back till she passed and we inherited it. I know the thing was not put in four wheel drive very many times in it's life. So basically what I am saying is the Jeep was just like new when we got it with less than 20,000 miles. Back to the story of dw. I couldn't find anything wrong so I took it to an alignment shop that I have used for years and have always had good service from them. They couldn't find anything wrong so we drove it up the road. At 45 mph it went into the dw. The guy said he had never seen anything like this. He checked everything and did an alignment on it and it still, dw... After several attempts, he said he determined the track bar was the problem. $180. later he said it was fixed. I picked it up and on the way home it was still wobbling. Went right back and got my money back and found another shop. Same thing, not a clue what caused it but said I needed to replace all my bushings and tie rods. I asked why and they said they were all worn enough that they were all causing the problem. I didn't buy it. Now if I would go from 40 to 60 under heavy throttle, I could get past the wobble and it would run all day. But between 45 and 60 it would almost always wobble and violently!!! Eventually I replaced every part that can be replaced including tires twice because they would wear out fast. 4 or 5 shops tried to fix it and no one knew what to do. After putting up with the problem for several years and spending probably $2,000, I was thinking about what was going on when it was wobbling. I had even stuck my head out the window to watch the tire. What I decided was the toe in was causing the problem. I know it was aligned to specs at least 5 times but something was still not right! I got my tape measure out and a couple of pieces of angle iron and set the toe in to less than 1/8th of an inch. It was over 3/8ths when I first checked it. It has now been over 100,000 miles later and never once have I experienced the DW! I figured out the geometry of these suspensions cause this problem when they get to a certain harmonics. With the toe in adjusted in too far, the left tire will try to go right at a certain harmonic and when it gives in to traction making it slip, then the right tire will be trying to go left and at just the right harmonics the fight for traction gets to be more than the tires can support and they begin fighting and they start the wobble. Don't know if this is a good explanation, but when I took almost all the toe in out of my alignment, it fixed the problem. Even with 31 inch tires the wobble never came back. I now have over 160,000 and it runs and drives like a new one.... Almost.... lol...

[@jalowey]

I am not a mechanic....at all. Fill the gas tank, changing oil....that's about the extent of my knowledge. I bought a 2000 jeep Cherokee to learn how to work on a vehicle. I've changed out the rad, heater core, shocks, front brakes, wheel hubs, ball joints (fml....fun), and u-joints. I now have the death wobble when hitting @ 50mph but only when traveling in a straight line. If turning at that speed, no problems. Your video is great bro! Thanks for taking the time to make and upload this!

[@guano23]

Never even thought of just reaching up and turning the steering shaft. I've watched dozens of vids on how to solve death wobble. As soon as you turned your steering shaft I was look at the play in that track bar. Thank you for this info.

[@dannylinc6247]

We did these on Ford's clear back to the 70's. And the reason we DID NOT have to keep replacing new parts is you don't put petroleum lube on chassis bushings. Ford makes a lube for it or you can use (sparingly) silicone dielectric. They always said I was lying and replacing unnecessary parts but you just showed why and how I had to do that eventually to every vehicle with those arrangements. The body is centered over the axle and tires by the track bar. When it's free to flop, you see the body shift over the tires instead of the tires turning. If you like to mash the brake and turn in parking maneuvers, you can tear it up again real soon. Ease up and let the rotor slip thru the pads as the wheel turns. That's the way they are. Peace out. Those guys can eat it too.

[@elsydeon666]

11:54 XJ as a tent is the best tent idea I have ever seen. Also, the explanation of how death wobble starts is simple and amazing. The only thing I would add is to check tire inflation. My 93 had the shakes because the PO had some 30" BFG AT KO tires from two Presidents ago and the wheels won't hold air.

[@normansabin8322]

Bro I dont know where you came from or how long you have been doing this but this was one of the most amazing videos and craftsmanship I have ever seen. Good information and not too much. I want some of your murch. Thanks man.

[@arrowsmith647]

Does this work on a 2006 Sport X Wrangler? Could you provide that information and I will do the work. Our local machinic has no clue. Thank you for the Video.

[@riverdog1643]

Got to get my XJ fixed. It cranks but won't start, and when I put it in reverse before it quit starting, it had a really bad clunking noise. I've put a ton of money into it, but I will NEVER give up on it. Love these XJ's

[@incredulousd9408]

Had a customer who's Jeep had a seized caliper causing death wobble, would cruise like a Cadillac at 65 until you lightly tapped the brakes. Wouldn't do it until they were nice and hot. Very nice video. 🇺🇲🇺🇲🇺🇲

[@rdmgwinn]

After many dollars and much frustration my death wobble turned out to be A sticky caliper pin and a slightly warped rotor. I'm sure lift / camber didn't help. Been good for 2+ years

[@incredulousd9408]

@@rdmgwinn it was intensely scary lol. I was driving it for about 15 minutes about to call the customer and tell them I couldn't replicate the problem, next thing you know, tapped the brakes to turn around and I'm holding on for dear life. Thought for sure the steering wheel was gonna come off. Good times lol

[@blackbirdpie217]

Here's a trick for you, when greasing rubber bushings don't use axle grease but instead use Permatex silicone grease. It makes these go in like butter.. no vise just push in with one hand- and silicone won't deteriorate rubber like grease will. We've all seen those old motor mounts with the rubber all swollen and pushing out, petroleum and rubber don't mix without ruining the rubber.

[@kevinmassey2847]

[@genobrn8743]

Great video! This has happened twice to me on my pristine 01 WJ. One time on the original/factory steering damper(90k)- I replaced it with a shit after market. And a second time, 50k miles later- again steering damper and right lower tie rod. THE CURE: RANCHO damper and all tie rods replaced with MOOG product. Thank again

[@BigSalP]

Well I figured out your problem as soon as I saw what you did during reassembly of the poly and metal bushings. With polyurethane bushings you should never, and I mean NEVER use a grease that is petroleum based in any way. The two quickest ways of destroying a polyurethane bushing is to lubricate it with a petroleum based grease, or to not lubricate it at all. You should ONLY use a silicone based grease as a lubricant on polyurethane bushings. And you should do it often. To make the job easier and so you don't have to constantly remove the parts to grease them, you can drill and tap holes and in the joint and screw in grease zerks so you can use a grease pump making the job quick and easy.

[@wildestcowboy2668]

Excellent points BigSalt. This clown is the reason I don't let anyone work on my jeep unless I'm there!

[@lesliejohnson9893]

Martin I have used hand soap to install rubber bushings, slides easy and does not deteriorate the rubber.

[@martinbuilt]

That's a good idea. Thanks for sharing 👍

[@whachudoin3949]

Wobble was crazy every time i hit bump. Didnt matter how fast i was going. Scary ash driving fast. Bought a new track bar, installed it myself. Removed the old one, slapped the new one on, all in less than 40 minutes. No special tools required. And all from checkinv out you tube videoes about the deat wobble in 2001 jeep. Not a hint of wobble since. Been at least six months now. I think im the shizznit. Lol thanks yt.

[@martinbuilt]

you are very welcome, glad that cured it.

[@mikebiron7339]

Good to see you back on KZbin! Yes, I would like to see you build a track bar, and how to center the body over the axle with it. What measuring points to use, etc...

[@martinbuilt]

LOl...I didn't realize I ever left. Yeah, I'll get some parts together.

[@jamesca41987]

ATTENTION!!! An addition tip!! I've experienced this myself. I noticed when the track bar goes bad you can turn the steering left to right from 10 to 2 o'clock. If done at a normal turning pace while parked the vehicles front end will (wiggle) shift left to right independent from the axle and tires. It is very noticable and it is best to look from the drivers side along the outside of the fender of the vehicle and compare it to the tire and axle position. Your axle should not move under your vehicle this is the symptom of a worn out track bar. Hope this helps someone diagnosing this issue.

[@nathankinto5052]

This happened to me today, thank you for the attention to detail. Literally everything you described.

[@wildestcowboy2668]

Excellent points for my xj. The clown on the video is a joke. I wouldn't let him touch my jeep unless I was standing there!

[@DieselsHOGVlog]

I just found your channel! I picked up a 97 XJ in great shape about a month ago, and it had a bit of a death wobble until I put new tires on it, but being a former Ram owner I know it’s still something worn as well haha. I’m going to check this out. Lots of mods coming, but only 3” up. Thanks for sharing! Now to find the random miss at idle! ✌🏼

[@martinbuilt]

congratulations on your purchase of an XJ, yeah tires can be one of the causes of death wobble There's so many things that can cause it. Good luck with the random misfire, and thank you for watching.

[@MrWallyrooster]

This video supercedes all other death wobble videos. If I could pick just one, it would be this one. (Bleepin Jeep one is a close second)

[@martinbuilt]

Thank you!

[@doro19]

I agree!! Finally, after tons of videos, THIS made it comprehensible. Thanks!

[@nateyoder9372]

My grand Cherokee started doing this. Looks like I’ve got a fun project tomorrow.

[@troycharbonneau8643]

Nice informative video. Pretty straightforward way of checking play in steering parts. I'd be leery of reaching up in there with the engine and fan running, but I'll have to see how space there really is. And put the transfer case in neutral and chocks. Only thing I was REALLY hoping to see, was apples to apples test. See how it behaved on the same highway at the same speed, with the new track bar bushings.

[@bluesriot2]

after assuming my wobble was from the driver's side track bar mount , i flipped when i wet to replace it and saw how loose the passenger side bolt was, so that was the problem. still had the issue even with the new bar, till i went for a larger bolt recently, found at lowes . tough getting the 17mm wrench in over the axle to hold the nut where the 14mm used to just make it tho. so i used a heavy screwdriver blade as a wedge while i cranked down the bolt head in front , so far so good. and nice parking job on the outro !

[@jeromewelch7409]

Awesome project love the details, What about the grade 5 bolt you're using on the bottom of that track bar, I would use grade 12! and it should be a shoulder bolt with a spline under the cap providing for interference fit on the front side under hex head. You tighten the backside nut only... This ensures that bolt will not rotate or fall out providing the nut becomes loose or falls off...Peace

[@jacobhughes3863]

I like your video. Some might argue your bushing are warn out because of the wobble. Thoughts?

[@martinbuilt]

lol...then what caused the the death wobble. The death wobble went away after replacing the bushings.

[@wolfei263]

I just got a jeep grand Cherokee limited and it has death wobble...i am hoping to use this to find the cause

[@eliinthewolverinestate6729]

It's usually track bar. But bad ball joints and control arms can make track bars wear faster. Swapped lower control arms. And haven't had to replace track bar since. The stock lower control arms can become weak. You can even see some movement from lowers when he is showing track bar movement. It takes 2 opposite forces to make a harmonic oscillation. I run a horizontal track bar it moves with axle housing instead of steering. And ditched stabilizer so could mount track bar above the axle. The horizontal track bar seems to work better when going to wider rims. The wider rims change articulation angles.

[@TOOFERMAC53]

Use to watch Chris fix.. Until I found this channel.. excellent

[@uptownphotography]

Interesting video and great info. We have a 2 wheel drive Cherokee XJ (1991 w/227K miles) and we have the same issue over about 55MPH, but it doesn't always happen. It only happens if you hit some kind of bump to set it off when doing over 55MPH. Not sure where to look because the 2 wheel drive Jeep has a different layout in the front end... Phil Jersey Shore Area.

[@martinbuilt]

You should be able to look in the same areas where I pointed out the 2 wheel drive and the 4wdrive. They are really very similar, They should have the same shocks, Knuckles, tie rods, tie rod ends. It is very common for death. Wobble to start once hitting a bump at a particular speed.

[@uptownphotography]

@@martinbuilt Thanks I appreciate your info. We are actually looking for a 2nd XJ model only a 4X4 model (we'll keep the current Jeep also) as we like them so much...I'll sell my car as soon as I find a decent condition XJ with little rust and lower miles. It's hard to find them, but they are out there. Thanks again for your help. Phil

[@jlsgarage872]

Yourve lucky with your case, when I had a loose trac bar bracket, hitting bumps in the road a certain way would shake my wheels and steering so intensly I couldn't control it and they would chirp and only stopping the jeep would stop it

[@martinbuilt]

I almost had it that bad before. Turned out to be a loose track bar bolt. Couldn't get over 15 MPH and you would swear the tires were jumping off the ground.

[@steveblankenship5474]

I experienced the death wobble with a lady driving a Cherokee next to me on the freeway. It was a severe wobble and I slowed down with her and when she slowed down I noticed the wobble went away at 45mph when she left the freeway. Makes me afraid the drive my XJ above 80. Thanks for the great info.

[@billrockmaker]

Keep in mind that petroleum based grease can eat rubber. Make sure you get a silicone-based grease if you’re putting it on rubber parts. Like Sil-Glyde from NAPA.

[@martinbuilt]

Thanks for the heads up

[@mitchstephen5491]

I agree, I use tire soap for that kind of thing. It allows the parts to be assembled but then dries out and becomes sticky so the parts won’t move around. There is a product that is called P-80 grip-it, it is an assembly lubricant for rubber bushings. It makes assembly easy and it dries out and makes the rubber grip the metal so it won’t move.

[@jerrycannon6940]

A C-clamp works well too to push bushings in

[@josephsewell7292]

Hey Martinbuilt , love the video. My first experience with death wobble scared the living hell out of me in heavy 5 oclock traffic. Almost had to come to a complete stop for it to stop and it went away until a week later, hit another bump jus right again and it happened again. Considering how long it's been since you posted the video, i don't know if your still making any parts but if you are I would love to buy what I would need to raise my Jeep. Not sure if 6in or 4in lift is what I would need but would love to chat and get your opinion. Thanks

[@JorgeInTheTube]

Someone said that using a type of great to drive those bushings in can then lead to squeaks. What's your experience? Do you think that's just a bunch of crock? I have some squeaky suspension and was about to grease up some joints.

[@privateparty4900]

Bought an XJ with the typical 3.5" RC lift that includes (extended) tubular lower control arms. Measured Caster at 11 Degrees. Front end was otherwise tight but had pretty severe DW at 51-55mph. Adjustable Uppers and 5 degrees caster makes it impossible to actually DW but I can feel the vibration that would set it off when going over bumps. I'm curious to see what happens when I get the dumb excessive backspacing wheels off.

[@ViktorKelley]

How do we know what should or shouldn't be moving. Having never done this lol

[@BLAZEPSI]

For those who wants to replace their bushing due to Death Wobble. Get the one from Kevinsoffroad DUROMETER Bushing. It is HARDER than poly. It fixed my death wobble. Also check the bolt HOLE where the track bar goes, make sure it ddnt expand so much. The bolt can move and can cause DW.

[@aaronneuder7005]

I wish I would have known you back in the days whenever I was dirt track racing. Hey building cars from the junkyard fabrication was one of the biggest things for Street stalker UPS truck never drop anything off for me

[@Captain_Zero_]

I had a ZJ that would move ever so slightly at the axle. I ended up buying one from JKS and it would still move the same amount. I was very close to doing what you said and build one with two Heim joints at either end. However, that would require a frame mount like you have. Chasing down Jeep steering problems can drive one CRAZY.

I bent the sway bar bracket on my 2005 Titan. I was wondering what it is that I can do to leave it more 4x4 worthy without the sway bar but at the same time safe.

[@martinbuilt]

It is dangerous to drive on the streets without a swaybar. I have done it before and if you had to turn suddenly you could round the vehicle easily. I recommend building some HD sway bar brackets with swaybar disconnects and when you go off-roading you could disconnect the swaybar.

So I just bought a 1996 ZJ with a 4in lift and it has death wobble when going 30 and above. The guy we bought it from is a certified mechanic and claimed that it’s the ball joints, he bought new joints and gave them to us. I’m going to try and install them this weekend but do you think it could be the track bar as well?

[@martinbuilt]

As you probably know there's a lot of causes for death wobble. Before going to the trouble of changing up the ball joints I would try also removing the front drive shaft see if the death wobble goes away. Have you tried checking the bushings the way I showed in the video?

[@jabberwocky3347]

martinbuilt it’s my first car and I got it last night so I haven’t had the time to look to deep in to it. I’ll check out the front drive shaft and see if removing it helps but i may just go for it and replace the joints to prevent any more issues. With this being my first car though I haven’t had much or really any experience with cars, is removing the front drive shaft difficult?

[@montydaniels1054]

@martinbuilt. Martin, after I bought my 93 XJ Country, I started checking all the Jeep Cherokee related channels on KZbin. You & Dan H are my favorite ones and the only channels I go to for Tips &/or for any ''How To'' information, plus I enjoy just watching. Before I do anything else, I am going to go outside & do exactly what you showed in this video & see if there's any play on mine. To be honest, I still haven't taken my XJ over 50mph lol, so I haven't a clue if I do have that pesky and irritating ''Death Wobble''. The one thing on my XJ is it came with a 3 inch lift and I'm wondering if there were any part/parts on the front end that should have been replaced, to match the height of the lift. So any help in that regards would be great. Apart from that, with the 28 years on my XJ, I accidentally backed into the planter box at the end of our driveway, so I managed to damage the left-rear Bumper, so I 'll either get a OEM replacement for the time being, or try to find someone who can build a replacement rear bumper close to the design I'm thinking about. As always, great video Martin, thanks for posting it..... MD......... Edit: Yep, the Track Bar on my XJ was replaced when the lift was installed, with the correct extended bracket on the left side. The right side bushing &/or sleeve has a lot of play. Whomever installed the parts didn't even tighten up the bolt on the right side lol. Not that it would be the reason for the play but regardless there is a lot of play. What bothers me is, unless the lift was done years ago, why would it go out so quickly... I mean the other end still looks new/newer to me anyway...... Thanks again for the upload martin, I was ready to look elsewhere for the problem. You saved me some time that's for sure....

Hy. I have also death wobble on my XJ. I lifted him 9 inch with a lift kit and have 37 inch tyres on it. All is new on the sterring and on the axles but i allways had death wobble. I don't no what can i change anymore. Sorry for my bed englisch i am from Bosnia.

[@martinbuilt]

That is a lot of lift. It is most likely that caster angel on the alignment.

[@mahmoodaldeeb]

Man thanks a lot Almost changed the whole front end But after I watched your video i found the problem and got it fixed in 15 minutes

[@martinbuilt]

That's awesome, thanks for watching!

[@markc6207]

New sub I am working on mt 2000 XJ it is coming along good. I will be watching your stuff to learn more thank you.

[@gregj.gotham4402]

Just bought a 2001 XJ today. Coming home I had the death wobble seriously horrible death wobble. Previous owner put it in a brand new track bar a week ago one of his selling points. I look under and hells bells to me I believe he had put in the wrong part. I now own it so I’ll fix it. He had put in 2” pucks up front and a helper spring in back. I’m going to buy 2” longer coils and a new set of leaf springs, he said shocks are new they look it but who knows. I experienced the death wobble some eight times coming home from Scranton pa to Syracuse Ny. I know why it’s called the death wobble for fact.

[@martinbuilt]

Make sure the bolts to the track bar are torque properly. Congratulations on your new purchase, you bought a vehicle that is going up in price. And will be a collector's item.

[@jefffowlerr]

Most of the time it could be the end of you axle I think it would be call the cv joint or axle bearings are bad it will bend one way but not the other without a wobble

[@MCKing441]

Hey what are those lights on the right side of your dashboard

[@martinbuilt]

those are rock lights, electric cooling fan, manual over ride for the transmission and the on board air compressor.

I don't even have a Jeep but this is good to know, nice Jeep BTW.

Thank you, and also thanks for watching

[@sonnydayz2118]

Is that grease compatible with that rubber?

[@martinbuilt]

I would recommend using a clear silicone lube

Nice video.. Im looking into buying a xj myself and has a bunch of upgrades done on the steering system but they said its got death wobble plus a poping sound when you turn left and right.. I looked at the gear box and there is some movement there is that something thats easy to tackle or should i just walk away from it.. Any advice would be appreciative...

[@martinbuilt]

That does sound like the steering gearbox. That would be easy to replace. If you like that Jeep buy it.

[@Bennett-xo6iu]

@@martinbuilt ok thanks.. Yeah its nice its already got a 4.5 lift kit on it with new control arms with those heim joints..

[@Bennett-xo6iu]

@@martinbuilt now is there some kinda plate that or kit i can purchase to fix the gearbox or need to get someone with a welder?

[@martinbuilt]

@@Bennett-xo6iu do you mean there's something actually wrong with the frame that the gear box mounts to? Or is it the gearbox itself? I built my own Hydro assist steering gear box that I purchased from Pick A Part that had a four bolt to frame bolt pattern.

[@Bennett-xo6iu]

@@martinbuilt as you turn left to right you can see the gear box moving from the frame.. It looks like someone had put new bolts in it but there is no plate on it to reinforce the gearbox

[@douglaschristian2909]

I like to see track bar build, r u running 33? I'm running 31 and time for newer bigger tires for my xj

[@martinbuilt]

I'm running 35's with 4.56 gears. I will get some parts together for the track bar.

[@muftahbourgheid8832]

very nice work Sir

[@martinbuilt]

Thank you

[@greynolds17]

ive replaced most of my front end...still got wobble...not as bad but its wobbly...next thing to check is the sector shaft..Im on my second track bar too and the bushings keep going out...might get poly

[@martinbuilt]

keep us informed, good luck!

[@natetaylor7687]

I believe checking steering as he did is the best way. I do it not running as to put more stress on stuff. But if nothing is worn out I'd look into alignment. If a shop is too lazy to adjust caster it can cause issues.

[@3737slim]

I have a 05 tj 0 to 40 no wobble 40 to 45 a slight wobble but anything before 40 and anything over 45 smooth as can be. Checked wheel bearings and ball joints all seems to be fine. So what would make it wobble between 40 n 45mph?? Also I have new track bar and it's tight as can be also have all new suspension lift n 33x12.50's wobble never started until after the lift it's self

[@martinbuilt]

I would have a look at your driveshafts, mostly the front one.

[@3737slim]

@@martinbuilt thanks I'll have someone take a look cuz I'm bout as mechanically inclined as a 2yro lol...thanks

How much would you charger if someone asks u to build one the bars and the fittings

Martin , I have a question regarding my 05 JGC 4.7 limited. I'm getting horrible gas mileage ... 11-12 street and about 16-17 hwy! Bought a new fuel filter but I'm wondering if it needs new fuel injectors or anything else. Any advice? Btw my jeep has 151k miles on it. I'm the original owner.

[@martinbuilt]

The fuel filter is a good maintenance thing to do especially with 151000 I don't think you'll get you any better gas mileage. Replacing the fuel injectors or having them cleaned can definitely improve your gas mileage. Replacing the spark plugs and air filter will also improve fuel economy.

[@LuisManuelHdez]

Thanks for the reply, I replaced the spark plugs about 10k miles ago or so, air filter just a few days ago, so now moving on to the fuel filter and finally fuel injectors. I use the fuel system liquid cleaner every so often. Any way just trying to get it to be a little more economical. Not an easy job with these guys. Even those v6s are not good mpg wise. Thanks again! I enjoy your vids. Keep um coming.

[@ALDA2479]

I recently bought my first xj I don't so much have wobble just driving but if I hit bumps rail road tracks or anything the steering wheel rips out my hand and darts any direction any advise or help is appreciated

[@martinbuilt]

That sounds like bump steer. Is the Jeep been lifted? And if so I would look into the alignment of the drag link and track bar are they parallel to each other and are they the same length, if one is greatly shorter than the other this will cause bump steer.

[@susu-mi7kx]

Can you tell me what the size of the rear brake line for 2001 grand cherokee is??? the ling line fromm rear to front?? is it 3/16, mines is spraying out my brake fluid. I hope you reply

[@alm7707]

I've changed lots of these usually on dodge 1 tons. Modify your steering and install a lift kit, do several things, think of new ways to make your vehicle try to kill you.

[@davec7]

They should just call it " The Repair Wobble" because all you got to do is inspect & repair the front suspension ✌

[@grandtheftdaddittv5418]

Martin, you the man.

[@galovintimilla1150]

Can you build bars for Range rover p38 too?

[@martinbuilt]

looked into it, looks very similar to the XJ bar. Very simple build.

[@Slobberdog66]

Great video keep em coming. 👍

[@astrojetson4958]

That petroleum based grease is gonna ruin the rubber bushings.. I always use white grease on rubber

[@maximdahomie5666]

It was the alignment for me and my dad

[@martinbuilt]

yes to much tow in can cause death wobble.
