Adding a second axle to trailer and bearing replacements.

[@sixtyfiveford]

Nicely done. I buy, sell, fix trailers and there are a few things you should know about your axles. First "Bearing Buddies" will not help at all with a non boat trailer. They are designed simply to not allow water to get sucked into the bearings when it is dunked into the lake after a tow to the lake and it cools down. They will do nothing on your trailer and you're better off with a cap. Side note, your new front axle is a grease gun able axle with a zerk and port to feed both bearings, your back/old axle will always have to be greased by hand. Second the bearing will always warm and expand as you tow so a little wheel wobble is what you want. Your bearing galled because it had no where to expand when it was warm. Looser is always better. Only with the wheel on should you adjust the bearing. Spin the wheel and tighten the nut to smash out the grease and seat the bearing against the race. Loosen it up until no pressure then lightly tighten it until you feel just a little drag and then back it off 1/4 turn; done. Now take your needle nose and channel locks on your first trip. After you drive a decent distance and stop for gas run around your trailer and put your hand on every hub. If you feel any warmth, that bearing is too tight and will fail. Take your cap off, pull the cotter and loosen the nut 1/4 turn. Trailer looks great and still love your lift to the ceiling contraption.

I don't think his frame is rated for 7000 lbs even though his axels can support 7k lbs. His frame needs to be thicker metal and probably 1 inch taller to support this weight.

[@oldgeeser]

@@HealthSupercharger Ya it should carry 7000, I built a trailer for my boss one time and he specified a 3" channel frame and the first load he carried was an E350 extended van . Steel is amazingly strong

[@vanblindguy4600]

I've always thought there should be some sort of bleeder added behind the rear bearing so as you add grease to a bearing buddy you could open the bleeder and it would push the old grease through the bearings and out the back rather than ultimately blowing out the rear seal. My boat trailer uses 90W gear lube bath this seems so much better than grease. Love your channel.

[@larrymcgarage2152]

Hey Doug, looking at your old bearings, that pitting is called chatter. It happens when bearings aren’t properly greased and or to loose or to tight. Watching you pack your new bearings. I saw that you rubbed grease around the outside of them. But you didn’t pack grease on the inside. You have to force grease to the internal part of the bearing. They make a grease packing tool that is inexpensive or you can do it by hand. Put a small amount of grease in the palm of your hand and use your other hand to push the bearing into the grease around the edge of the bearing. I’m sure you can find a KZbin video on this procedure if you look. Just saying. The bearing you greased on this trailer will fail prematurely. Also makes me wonder about your bearings on ratchet and mauler. Maybe you did the proper grease packing procedure off camera that we didn’t see. I don’t know. Just trying to help you out.

[@DougBugBuilder]

Appreciate the advice, and I agree I need to get more grease in the bearings. Ironically I just purchased a tool that I can use with my grease gun to pack the bearings before I put them on the axles. I think that's what you're talking about. Don't worry about Wratchet, his hubs are from a 4Runner and come pre greased from the factory. Same for the rears on Mauler, it's just the fronts. But if I remember I packed those pretty good.

[@billybike57]

I’ve just always used the palm of my had until the grease squeezed out around the bearings and move around the race until it’s completely packed.

[@breadmenv]

I’m glad someone pointed that out already.

[@cole4406]

I enjoy the way that you reason through things logically. Pro tip, with the outer bearing removed, thread the nut back on the spindle and use the hub as a slide hammer. Couple of shots and out comes the inner bearing and (usually) a reusable seal!

[@DougBugBuilder]

I'll give that a try, thanks for the tip.

[@lunkydog]

When you add brakes, they should be fitted to the rear axle which sounds counter intuitive, but if placed on the front the equalizer will force the rear axle downward and lift the front making the tires more prone to locking up. My buddy has been in the travel trailer and RV business his whole life and informed a high end boat trailer company that they were putting their brakes on the wrong axle and they corrected from then on.

[@DougBugBuilder]

Wow thanks for the tip! I would have absolutely put them on the forward axle thinking that was better.

[@lunkydog]

@@DougBugBuilder That's why I said it was counter intuitive. When he explained it to me after the boat trailer situation and you think about the torque reactions, it makes perfect sense.

[@oldgeeser]

As a welder, I think you did a great job, but I would have welded up along the spring hangers instead of across the frame. Great video. Edit, One more thing I really like your square tube axle, looks home built and also looks strong, good job.

[@DougBugBuilder]

Thanks, appreciate the kind words.

[@bricra8992]

Nice video. I'm in the process of replacing my bearings right now and found this really helpful. Not sure what I'm in for since the grease fitting was damaged and I don't know how much grease was actually there. Thanks again.

[@b-lopez394]

Doug Bug, Since you used two different design of axles, the equalizer probably is not setting horizontally when the trailer tires is sitting on the ground. You can make it close to horizontal by installing the rear axle below the leaf springs to set the spindle height lower in relation to the spring. The equalizer can rock better to distribute the load in an uneven road surfaces. I included the correct procedure to pre-load trailer bearings. Stay Safe.

[@DougBugBuilder]

I think to level the equalizer I'll just make a set of shackles a bit longer to bring it back level. I knew it would be off, I just didn't know how far off it would be.

[@kene6838]

Damn Doug a jacket and shoes , must be cold. I’m in Florida and it was 38 this morning and I can’t move much further south. That hoist system is nice.

[@DougBugBuilder]

If I'm wearing shoes you know it's cold! 😉

[@dodgeme1986truck]

when I use equalizers for tandem axle setups, I always use either a greaseable bolt (has a grease passage going through with a grease fitting in the bolt head) or I drill and tap a grease fitting into the equalizer for all 3 pivot points (I usually make my own equalizers anyway and I incorporate greasing into the design anyway) I have seen way too many trailers where the equalizer pivot bolts wear to the point of breaking because they didn't get greased. I also make my own grease point chart attaching it to the trailer. what works better than those bearing buddies is tapping the backside of the hubs between the seal and the inner bearing, I then put a hole in the factory dust cap and use a push plug. pop the plug out hit the grease fitting with grease until fresh grease comes out the hole, pop the plug in and good to go.

[@DougBugBuilder]

Good tip on the greaseable bolts, I'll look into that.

[@catlifeoutdoors6369]

This is so true. Have a trailer in my shop right now from this exact thing. Shame the manufacturers won’t install these new. It’s all about the end price I guess

[@vintagetintrader1062]

Watching you tap the edge of the bearing cup into the hub with the punch had me cringing, best way is to use the old bearing race to seat the cup. Sit the old race in the new cup and hit with a hammer or preferably a press, then throw it away. No damage to the hub and it fully seats the cup, quick and easy Have done heaps that way, use to buy and restore trailers.

[@DougBugBuilder]

That's a good tip, I'll use that next time. I hear you on using hardened steel on hardened steel. But that's how I've always done it. 🤷‍♂️

[@michaelkirwan177]

Could be wrong on this, but I think your problem with the pitting on your rollers and your race are the result of two different factors. One is the likelihood that your trailer was parked with a relatively high weight load on board without being moved over a protracted period of time. The second is the phenomena of compression electrolysis whereby two different metal alloys, when compressed, exchange metal due to interactive electrolysis. You cannot polish-out this disparity once it occurs because while it might work temporarily the reaction will recur so the solution is to increase the bearing quality as well as a higher-heat grease formula. Mike Kirwan - Kenmore, WA

[@Paul_VanGo]

It looks as if the bearings have been overtightened. Due to thermal expansion, when using the trailer, the initial preload became too tight. Thus the rollers sank through the grease and they got destroyed. Common rule on these types is; to tighten them, so that the washer under the nut still can be moved (just) with an screwdriver. If you have one, see the procedure in a VW Bug repair manual.

[@DougBugBuilder]

Interesting technique, I'm curious now, I might pop one of the caps off and see if mine can be moved. ✌

[@Paul_VanGo]

@@DougBugBuilder Some say: tight, -¼ turn, +⅛ turn, but I prefer the thrust washer check. Also, because you changed the races, and they might not be 100% seated, you might want to give them a check after a drive.

I highly recommend water resistant grease such as one would use on a boat trailer. It resists moisture that will try to creep in after a long run and the weather is cold. Synthetic is best if you can find it.

[@seanceschia-realestatebrok4466]

Great work overall. But if you notice, the rear axle has a higher spindle than the front axle. Therefore the wheels will not be lined up! 2 front tires will be lower to the ground.

[@vicferrarisgarage]

Im first. Lol That is heat galling. It was melting the race surface and then smashing it back on. I would only tighten a little to seat your grease then undo and tighten finger tightness and run high temp pink fiber grease. I overloaded my trailer to 3800 on 1 ton axle & had no problem coming to Florida! I’ve never heard of any torque setting but I literally only use my fingers after preloading the grease once. I watched how you tightened it and it looked like what I do when I’m preloading. Not that my way is right. Also I take my laser gun and if they reach more than 130° at hwy speed I feel as if I’ve got them too tight. After about 50 miles they always run around 90° to 120° depending on Arizona winter or summer. Take care Hope that helps good luck

For a bump stop/travel limiter, you can put a piece of rubber hose through the middle spring hanger. Stuff the hose with rubber rope or a smaller diameter hose. When the equalizer travels up, it hits the rubber instead of the frame.

[@zacharybarton8220]

You really need to get another straight axle, so your axles are the same type. It will be bad for the suspension to run 2 different kinds of axles. When you load your trailer correctly with tongue weight, you run the chance of the equalizer maxing out and a bump can actually cause the front shackle on the rear axle to invert when the rear axle unloads a little.

[@DougBugBuilder]

I can't argue with your logic. I'm looking at replacing the drop axle with a round straight axle. Thanks for the feedback.

[@dannyc1657]

Yes the fact that there is a straight axle on the front and a drop axle in the rear is going to cause issues from suspension travel to possibly tire wear problems. I would invest is another rear axle as soon as possible. Another think to consider is to loosen all suspension hardware along with u bolts and tighten these with the trailer on the ground under load. Good luck and the trailer looks great!

[@brianehly1954]

I thoroughly enjoy the channel and the builds, BUT... there are so many red flags on this one. Two different axles (one round and straight, one square and a drop), no brakes for a trailer with 7000 pounds of total capacity (3500 pounds and above rated trailers are required to have brakes), IDK if this makes a difference but when you fit the springs the shackles were up and when you mounted the springs the shackles are down. Concerns Doug, I'll still watch and follow.

Hang in there buddy, this isn't done. In future videos I'll be adding brakes, fenders, and correcting the equalizer off balance from the different axles.

[@b-lopez394]

Pre-Loading Trailer Wheel Bearings Pre Loading Bearings: Whenever you install new hubs or new bearings and races into an old hub, you should pre-load the bearings. Pre-loading the bearings assures that the races in the hubs are 100% in place against their machined stop points and keeps the hub from wobbling after a few miles. To pre-load the bearings, install the spindle washer and spindle nut onto the spindle with the hub and bearings in place. Tighten the spindle nut finger tight (until snug) and then with channel-lock pliers or a crescent wrench, tighten the spindle nut another 1/4 turn or about 15 to 20 ft pounds of torque. Now turn the hub ten revolutions. This will fully seat the races. Now loosen the spindle nut very loose, then re-snug to finger tight, and engage the nut retaining device (some reverse lubricating spindles use a tab washer for the retaining device).

[@DougBugBuilder]

I did preload them like you said, but after I loosen them and retighten them I go a little tighter than finger tight. I haven't packed them with grease yet, so I can still get in there and make adjustments if needed. Thanks for the tips.

[@waynenocton]

At first the axles seem too far back, but then I remember you haul rear engine stuff. Curious of what your tongue weight will be when both are loaded and if your equalizers will be level.

[@DougBugBuilder]

The tongue weight was great with Mauler. Trailer was super stable. Not sure on Wratchet yet. I need to get him up there (between the tires) so I can weigh things. Then move him forward or back as needed. You are correct, most of the weight is back, so I kept the axles way back there.

[@vanblindguy4600]

Me running to the comments to see everybody shredding his bearing packing skills. Unless he pulls this back apart or adds bearing buddies those bearings wont last 200 miles. After recently buying a new 14k trailer and having the bearings getting warm while towing the trailer completely unloaded just to get it home if found that that factory apparently used his method for greasing the bearings. Ended up adding almost 1-1/2 tubes of grease to get the (factory installed) greaseable spindles full.. CRAZY. Yes I know bearing buddies aren't installed to alleviate greasing the bearings but in this guys case (slight phobia of dirty hands) it would have been better than what he did. But that being said otherwise this guy has great fab skills and that ultra clean shop is outside my skill set. wink wink.

Does the axles sitting at two different heights above the springs affect the suspension at all? The old axle has an elevation to the spindle, the new axle has the spindle in line with the axle, causing them to be at two different heights from the springs....

It doesn't affect it in handling or anything like that. But it does make it so one axle is closer to the trailer frame. Going over large bumps sometimes I can hear it contact the frame. That's not good. I don't recommend it if you can avoid it.

[@timgroh8616]

So one axle is a drop and the other is straight? That will put your equalizer out of balance so to speak. You might consider putting the rear axle under the springs.

[@Reman1975]

These solid axles often have a tiny bit of castor and nose in built into their geometry, so it would mean cutting off the mounts and welding them back on the top. Not a huge job for a guy of his talents, but worth mentioning as a lot of folks just flip them upside down, then wonder why the trailers wandering all over the place on a bumpy road. Personally, I might have used this as an excuse to leave out the equaliser all together and stack the middle spring mount one above the other to get the wheels 5 or 6" closer together. With the straight axle on the back it could have the shackle links on the trailing edge of both springs, this would give it fewer wear points, and it would have less tyre scrubbing during tight manoeuvres. On flat roads he's not going to miss the equaliser, but on rutted tracks this setup would be slightly more likely to bottom out a spring if he's motoring alone while heavily loaded though.

[@DougBugBuilder]

I wasn't sure how much of an issue that was going to be. I think if I do anything I'll adjust the lengh of the shackles on the equilizer so it's level.

[@DougBugBuilder]

I thought about not using the equalizer. But like you noted I really want the equalizer to smooth things out over the bumps.

[@timgroh8616]

@@Reman1975 how would moving the axle below the spring change the castor or camber?

[@Reman1975]

@@timgroh8616 As I said, a lot of these axes have a tiny bit of toe and camber built in to aid trailer stability, so from new they have a "This way up" and correct direction of travel. Most people don't know this and assume the stub axles are totally parallel, so when they see the spring perch plates welded on the bottom they just assume the easiest option for them is to just flip the axle upside down when putting it on the other side of the spring. This makes that built in geometry work against the trailer being stable at speed. Because of this, the CORRECT way to move an axle from one side of the springs to the other is to cut off the spring perches, and remake them on the other side of the axle rather than flipping it over.

What’s the reason for going from single to tandem axles? I might have missed that. I have a single axle toy hauler for UTV, that I am thinking to convert it tandem axles.

[@DougBugBuilder]

I needed more capacity, it seemed better to go tandem axle verse a larger single axle. The tandem axle is smoother on the road for sure. But I do think going with a larger single axle would have been simpler.

Always better to not over tighten bearings as they expand when used. A smidge of wobble is okay.

[@DougBugBuilder]

Yeah, can't argue with that. Thanks.

Lol, yeah something like that. 😁

Nice garage, grinding with expensive cars next to you isn’t good. When I seen your “packing” job I knew what. Check with your home insurance & make sure it’s paid up & covers fire. Grinding & welding with carpet is a sure way to start a fire.

[@philliplawson2001]

I believe they call that SCORING AND PEELING Timken has a guide for bearing failure online. " Tmken bearing damage analysis reference guide "

[@leehwhiz]

I'm not sure why you didn't add brakes before you put the wheels on to begin with. Also, on a trailer like this both axles should have brakes.

[@grantlee5393]

shouldn' t those bearings be packed with grease?

[@DougBugBuilder]

Yep......I don't have any grease for my grease gun. I should have noted that in the outro. I'll pack them when I get some grease.

[@grantlee5393]

@@DougBugBuilder when I did my ranger I pre packed them with the hungry hippo method, pretty messy but it gets the job done

[@DougBugBuilder]

@@grantlee5393 I can't get that greasy....😂

@@DougBugBuilder I just watched this video and it was my 1st video of yours i have watched but i actually said that to myself!! It looks like you REALLY didnt want to get any grease or dirt on you. HaHa You look like you do very good CLEAN work and thats a good thing but every now and then, a guys gotta get them fingernails in the grease! Im glad you addressed the bearings not getting greased right in your above comment because they were not even close to being done right. That old grease looked really thick and i have never seen that thick grey type before, could it have been too thick to actually lubricate the old bearing good enough? Anyway, really good job on the new axles.

Rust from moisture. Take off yearly clean and repack. Bearing buddies do not clean out old grease laden with .oisture.

[@andysmith8295]

Whatever grease you were usng doesnt look right., grey color?? did you get water in the grease maybe??

[@DougBugBuilder]

Not really sure, those were packed by the previous owner. This was my first time taking these hubs apart since purchasing the trailer.

[@autobodyrepairclearcoot4146]

hello I just Find your Channel it Looks Cool Im thinkng to Build my First Trailer Cuz I cant Offer to bay one my Question is Wher Did u Get Your Springs And Axels Did u Order From China or Local ? Thanks

[@DougBugBuilder]

The axles I got local on Craigslist, they were used. The springs, shackles, brakes I got from a company called Trailer Supply Depot.

[@jakearmstrong4563]

Referring to your inside bearing, those “ridges” are referred to as pits The metal is pitted, porous and Not plane

[@frediefarmer]

👍🏽🇺🇸👍🏽 looking good

[@DougBugBuilder]

Thanks!

[@dunerinaz]

Good video, but no one is here to watch you vacuum your shop floor

[@billybike57]

Just gotta mention one thing, before I do let me just say, you do incredible work, you really do…. But you ain’t packing those bearings correctly.

[@DougBugBuilder]

Don't worry, the front axle is a Dexter E-Z lube. After I installed the hub I packed the entire thing with grease using the axle zerk. And I'm installing brakes on the rear axle. So when I grease those new hubs I'll be sure to grease properly. But I appreciate the honesty and watching out for me. 👍

[@bruceb6262]

Nice trailer but, its illegal in most states where are your brakes, most require brakes on anything over 3000lb axles. Have a panic stop with that loaded Yikes

[@DougBugBuilder]

You are right, and since this video I have installed surge brakes on the rear axle. I should do an update video with that.

[@gregmiller2494]

Aluminum wheels would look nice.

[@DougBugBuilder]

I can't argue with that. 😁

[@derrickbilodeau1435]

That axle nut really shouldnt be any more than hand tight. You fried the bearing by having to much preload on it.

[@mikethompson9745]

If you "Packed " the old Inner bearing like you did the new one that is why it failed, Not enough grease Repack that bearing. your axle position is wrong, You have to much tongue weight, Dexter Axle has a ton of information on the position and spacing. Take a look , Also In many states a Single axle trailer isn't required to have brakes, However In Washington and Idaho if the trailer has more than one, then all axles are required to have brakes ,might check your jurisdiction. not that anybody will hunt you down and cite you , however after the crash the citations are written. You carry expensive side by sides Why wouldn't you want to protect them in a panic stop? Like everybody I am an expert, I am a trailer parts distributor in the Northwest.

[@georgesimpson3113]

That's not how you pack a bearing... maybe you should buy a bearing packer if you can't do it by hand. That is why the other bearings did what they did. That wasn't 'packing' the bearing. That was just smearing some on it. I think you would have been better off keeping a single axle, but upgrading to a 5K axle & springs, with brakes. Now you have double the bearings to keep track of, another set of tires to replace and they will wear faster than a single. I would have gave another 1/4" farther distance from center to outer spring mount. Remember springs get longer as they compress. And you are so set on cleaning up but then breath in the grinding dust and welding gasses?

[@DougBugBuilder]

I'm really torn between single or tandem axle. When it was single axle it was more maneuverable, and didn't scrub at all. Now when I turn out of my driveway it leaves tire tracks where it scrubs. But the one aspect that keeps me from going back to single axle is how the tandem axle takes bumps so much better. The tandem soaks it up, where the single would really hit the trailer hard. I think in my dream world it would be a single 5,000lb axle with air suspension. I have since added hydraulic brakes, but it's still a work in progress.

[@larrygreen8912]

Put the old wheels on one side of the trailer and repaint them. No one can see both sides of the trailer at the same time 😅

[@DougBugBuilder]

Not a bad idea there. 👍

[@fishhuntadventure]

2:54 why is your axle welded in place?!! 13:02 from the way you DIDN’T pack the bearing that’s why 7:48 the bearing failed. Sorry, I know I sound like a critical jerk but I’ve likely done thousands of bearings at this point in life and I don’t recall any come-backs for early failures (or on my own stuff for that matter).

[@pauldietrich9199]

your original axle appears to have a offset the other axle does not......
