Finishing the Rear Axle on the - Mini Rock Crawler Project - Part 2

[@jakelords24]

You have a lathe. Cut a male end on one axle end and a matching female on the other, then weld it together. That's how I shorten my full size axles

[@eriklarson9137]

Can you show us?

[@JETHO321]

​@@eriklarson9137 Its pretty straightforward how he explained it.

[@Unforgettable_Name]

Couple them with a sleeve

[@tujuprojects]

Not enough penetration.

[@erikverhoeven2853]

That works fine if you shorten the axle but not if you don’t have the length for it …

[@bryduhbikeguy]

That looks like a good gear ratio for rock climbing and hard hills, when in low-range. The new rear 'diff set-up' looks good.So glad you finally listened to people and painted it with "Weld-Through Primer" so it doesn't look like crap, like the rest looking like it was dragged from a swamp.

[@neilkirkes]

I gotta say, creating a solid axle, out of a independent suspension system is rad! Now you have me thinking about something crazy.

[@AA-tb4ff]

if your gonna do that you can mount the hub bearings lower and get some more clearance

[@Feketekutya]

Yea if you do it that way,then you need to take out the full potential of it.

[@renoreno2701]

It is a Rock Crawler : with this system one wheel can be very high and the other very low.

[@neilkirkes]

@@renoreno2701 you aren’t picking up what he is putting down. Look up “Atomic axles” if they still exist, and you might understand what he is talking about.

[@joebufford2972]

I love the way. Chris narrates while focusing on the part and he is only in the frame waist down. That shows true dedication to your work!

[@richball9576]

You really do such amazing work Chris! I'm glad to see you transitioning more toward driveshafts and differentials instead of chains and sprockets. Great work!

[@unusualpodcast]

I have seen every video you ever did, don't remember you doing rear steer ever.❤fire

[@xpndblhero5170]

I can't wait to see what it looks like when it's done, and maybe you can look into a thinner oil for the rear shocks so they're not as hard a they're now.... Awesome build, awesome mini rock crawler and keep up the great work. 😁👍

[@christopherallen9615]

I think the small projects are cool because you can fit in those narrow trails that they have nowadays. Around here in kentucky, a lot of times if you're more than 52 in you can't fit through the gates at the trails.

[@BrookZerihun]

Best part of my weekend, great work

[@BraxxJuventa]

Thanks for filming again Chris. 😁👍🏼

[@coreywhitaker9619]

Man I would love to see some local ironworkers help this guy put up a pole barn shop. He needs it!

[@186scott]

With replacing/upgrading the front axel you could strip it back to the frame then start from the inside out and use the old suspension arms to make a jig for the new ones so when you place the bigger hubs on the jig you modify the jig saving a bit of time

[@whosaidthat5236]

The Fabrication series channel made a cool downdraft table for grinding dust. You should make one for yourself with the stuff you work on it would be a great time saver in cleaning up old rusty parts.

[@CourtJ_ml9to]

Yep,start from scratch, do it right, thicker wall tubing, four wheel steer, you'll be glad you did . I❤🔥

Love to watch your videos. Great content!

[@OmnieStar]

Nice! LEts gooooo!

[@ÁREAJ27]

Que maravilha amigo!!!

[@crazytestpilot9434]

I would have widened the rear axle setup to fit a uncut axle. Looked like it was almost there already. Also there are recommended ways of welding axles so they don't break, you may be interested in checking that out.

[@jesterclown86]

Great video making a lot of progress on it. 👍👍

[@spenny3403]

I love everything you do brother, the welding work is incredible! I just have always wondered why you never end up painting any of the framework or anything after you go through all the trouble of cleaning it off and getting it pretty looking?

[@ratherBweldingChris]

I like to make sure a project is 100% done and tested before I paint them. It makes modifying something like this a lot easier if it’s not painted

[@BBC.Customs.2]

​It's not necessarily a cheap option, but they do have weld through primer that's popular with fabricators to prevent bare steel from rusting between stages. Steel-it is the most common but others exist as well. Just a suggestion to help save some time in the future ​@@ratherBweldingChris Edit: words

[@CreeperCustomPaintball]

When drilling hardened steel, I like to use 1/8 bits for a pilot hole, then step up from there. You can get a pack of 1/8 bits for cheap. Once the pilot is there its easier drilling just stepping up one size at a time.

[@JETHO321]

Low speed, high pressure and alot of cutting oil.

[@thomaspryor8202]

Well done!

[@dodgeme1986truck]

Here's a trick to prevent overheating the knuckles when replacing wheel bearings take a crayon and rub it on the part in a few places when the wax stats to melt and stay molten it's time to install

[@186scott]

You can also use washing up liquid

[@BUILDNIGHT]

Solid CARBIDE Drill Bits will cut right through hardened steel.

[@leehedger5056]

Having a solid fixed length propshaft will break or damage the rear diff very quickly when the suspension moves up and down. It needs to be able to vary in length like a telescope.

[@Davespackey]

💯

[@robertmoreau9382]

No it won't. Have you ever seen a rock crawler with a telescoping prop/drive shaft? The drive /prop shaft is the same as on a regular size vehicle. You don't get the straight up and down articulation like on a pto. You get more roll articulation.

[@leehedger5056]

@@robertmoreau9382 yes they all do otherwise something has to break, most props on road cars slide in and out to compensate for suspension travel on the splined end at the gearbox but Chris has put a bolt through both ends........

[@enigma9789]

@@robertmoreau9382 You are wrong. They all have a slip shaft of some sort.

[@musicauthority674]

That is a lot of work for two inches of width. but Chris is a hard worker and he doesn't mind. it's a surprise that you got something off of eBay that actually worked? lately I have been having a hell of a time with eBay and it's been irritating. I definitely appreciate your redundancy for strength. although there are very rare occasions when beefing things up a lot doesn't actually help it's strength. I remember you using masonry bits in the past for the carbites in them. I made sure to remember that for when I needed to drill something that was hardened. who would have thought it would have been remembered for future episod of Rather be Welding?

[@BillWrites-t2e]

You would make the best RC cars , your a good fabricator you can do it...

[@mlsargent51]

This is still my favorite project of yours, by far! So cool looking! And what if you put limiting straps on the rear instead of bump stops?

[@oakwaterjimmy]

hydo steering for a boat would be the easiest way to do the steering

[@BillWrites-t2e]

Maybe you could use tire size to compensate for the mismatched gearing front to back, it would take a little math but it's an option to consider

[@mateuszkasza]

If bolt stuck just heat it up to arround 700deg until it slightly starting to glow. Than leave it to cool down in room temperature. Do not spray that. It will let the rust to back off and unstuck the bolt

[@sambuvca22]

Weight doesn't seem to be a concern, although your a fantastic welder.

[@colbygillette]

Just warning you, polaris differentials take demand drive not agl

[@JoseManuel-lj4dk]

Great video Chris I have a project my self with a artic cat 300 4x4 buggy wishing that I could finish , not enough funds but can't wait to finish lol😅

[@jimpollen9457]

When your tire flexes its usually the lower half of the tire doing the flexing. The top half of the tire should clear in most cases

[@robsorgdrager8477]

I would have left the rear as wide as it was and make the front wider . This helps in the turn radius as well as off axis grip.

[@MTCamaroguru]

Probably too late but why not lower the spindles 4-6" below diff? Make sort of a portal axle. Better yet down and rearward (on rear) or down and forward (on front) to improve approach and departure angles. Take advantage of the fact you have CVs and can gain some easy ground clearance.

[@kevinpulliam8029]

Could save lotta time n labor by using a solid axle from a small suv like a samurai or something

[@ksummers4630]

Lock tite anaerobic sealer for the diff halves

[@Hoodman84]

Hi! Don't forget to put fluids in the differential gearboxes!

[@ExoPhaz]

pretty sure he knows that

[@panda_of_trash7806]

As someone who as been watching for years staring with the Grave Ninja build. It makes me sad to see all the time and work you put into these videos undermined by all the Bot accounts in the comments. That said, this has been an awsome build to watch, and see the rock crawler evolve along the way through trial and error. Keep up the great work man. And don't let the bot BS be a set back.

[@musicauthority674]

He did a lot of upgrades to the grave ninja after he built it. I remember he rebuilt the entire front suspension after ripping a front wheel off of it. when it hit a tree.

[@panda_of_trash7806]

@musicauthority674 absolutely, a lot of his builds have been evolutions of trial and error. It's been great watching him build things and when it doesn't work out. Seeing him find a way to make it what he wants.

[@musicauthority674]

@@panda_of_trash7806 It's a great quality that Chris has. he is never too arrogant to point out his mistakes. and he learns quickly how to fix them correctly. it's why Rather be Welding has improved by leaps and bounds since he first started out.

[@tujuprojects]

Next time they make a new Mad Max movie, they might come knocking your door.

[@johnfarber6294]

What about using a watts link? Should give you all the flex you want, but keeps it centered.

[@lawrenwimberly7311]

softer bump, stiffer droop dampening

[@travissmith1599]

Need to buy a wheel bearing grease tool for a rzr. Most are a 40mm or 44mm bearing. They come with very little grease in them when new

[@BillWrites-t2e]

I'd fill the tires with water to get more weight down low and it helps for traction, get some sticky tires too... It's so light, rock crawling prefers heavy and low cg vehicles

[@briankuhn7396]

That would be A LOT of weight. Is this typically done in rock crawling? It's an interesting idea!

[@OzBull]

I could be wrong but when you weld high tensile steel it loses its carbon and tensile strength. I believe you can help keep it stronger by peening the weld.

[@andrevokey4132]

2 inches is huge, don't let anyone tell you otherwise

[@kevinpulliam8029]

2 inches at 90.mph can do a lotta damage

Please lower the PSI in those wheels man, They look hard as a rock. Great build, can't wait to see hard offroading with it 😁

[@keithhasafastcar]

He said in his last video on trail he had like 8psi in them. The thing just doesnt weigh a ton

[@BlackAndBlueGarage]

You may find that limit straps have a similar effect as bumps, depending on how your shocks are set up. In any case, limiting the down travel will hold your bump stops in a more controlled position, and research tells me that "too much" travel more often than not, a bad thing. Hate being the guy to tell others how to build their machine, but maybe hoping be helpful 👍🏻 it's at least worth a little research if it saves some trial n' error?

[@ksummers4630]

Should have center drilled the center of the prop shafts and put a bolt on the two halves

[@loudelvis610]

Case harden like a Tootsie Pop....1.........2........3...chocolate!

[@NARI_1420]

make the center point a damping spot under the gas tank or next to it and make the shock angle different to fix the damping. Please don't yell at me, if that it is a dumb suggestion.

[@calholli]

You should just use Dana 44 axles at this point, or something similar. Like the 4x4 axles under an old 90's 4x4 Ford Ranger or something similar.

[@gideonvanniekerk4252]

Jumping between projects is making it difficult for me to remember the previous episode of that build 🙈

[@scottwright388]

Same here, I watch every week for years now and can't even remember if there is a current project right now. I'm pretty sure he has at least 4 or 5 projects still unpainted.

[@revodrvr]

With the axle. I thi k it would be easier to use lather drill a hole in perfect center on both pieces use a small dowel as a locating pin to hold while u weld it.

[@maximeberube7490]

Less oil in the shock will give more space for nitrogen to compress so it'll degrease dampening

Ive been watching you for about 10 years now youve made a lot of crazy things happen in this shop, but do you have any plans for a shop upgrade?

[@scottschmehr8681]

Just do one central bump stop so the tilt wont matter.

[@camyota]

I meant to say it in the last video but polaris' logic on front spinning slower than the rear is wrong, at least for crawling. If anything you want the front spinning faster.

[@dipe277]

widening the rear axle will fix your bump stop clearance?

[@jasonlukasik5595]

I think if you machine to 1 inch hubcentric wheel spacers would’ve been a lot quicker

[@jimhillbilly0866]

It kind of looked like when you took your wheel off that the axle had moved to the right so is it staying centered or is it moving back and forth

[@darylSKYTZOwillis]

How about a spring bump stop?

[@darylSKYTZOwillis]

Wouldn’t it be easier to widen it an inch on each side with adapters or offset rims first, just to see if you like it first?

[@Friedbrain11]

Did you remember to put gear oil in the differential?

[@mikemc7704]

you were looking for a name or the name of the axle cage you were working on. I believe the industry calls it a carriage or carrier.

[@josealmeida8731]

Making wheelies without wheels that's a first

[@siupa23]

Won't it will be a good idea to use some CAD software, to prototype parts so you can easy iterate through ideas. It will save you the hassle, of constantly having to redo some parts and it's easier to spot problems with project?

[@lawrenwimberly7311]

LOL pushing it ( the chassis) out made it look like a dog wipin' his butt on the carpet

[@mkuhlman77]

Speaking of temporary garages. You should put barn tin on one before winter. Make for good content also and just a little change to maybe attract a different audience to get more subs.

[@mandrakejake]

I could be wrong but that rear diff doesn't sound happy. Perhaps a shim is missing inside?

[@MrArcticPOWER]

You definitely don't need pump stops on such a small machine.

[@catamaranoborchiato]

it's starting to look like nikko rc buggyes of the '80s that i had when i was a child, it need only a bumper in the front and a spoiler in the rear.

You don’t need bump stops

I think that no matter what else you have done so far you should have sleeved the weld joint on the axles. They are a weak spot. What you did to reinforce them is insufficient....round tubes completely covering the weld joint is the only way to go.

What size, thickness and type of tubing is he using?
