Welding a rear end

[riverbasher]

My buddies and I both need to weld our rear axles, but have no idea how to do so. My buddy has a good welder that works for him, all we need is some direction as to what we need to weld. We know we need to weld the spider gears together. Can you provide me with some insight? Thanks

When i do mine for the demo derbys i just make quick little booger like things so i dont get them to hot, its held up every demo i've ran, and thats what i plan to do with my truck. Thats my best info, it might not be the way everyone does it but thats how i do it and it works for me.

Some people add a bunch of silcone around the spiders (after they are welded) in case something lets go it will help keep pieces from floating around and damaging your ring and pinion.

i welded mine rear, i covered up whole spider gear, out to carrier shell. i shld have took a pic of it but i didnt.. u gotta weld it hot to stick it in, i had no problem after that.

[kxracer116]

I dont let mine get to hot or else everything gets to brittle. I think just gobbing it in there and then putting the silicone would be your best bet.

[CountryBoy2784]

interesting! everyone have their own ways! LOL. but best of all.. detroit locker, but jesus christ they're expenisve! :bat:

[riverbasher]

best of all.. detroit locker, but jesus christ they're expenisve! :bat:

That's why I want to weld it........

[kxracer116]

Yeah that would be the best most reliable solution, but if your pockets are empty i would just weld boogers in it and cover them with silicone.

[CountryBoy2784]

That's why I want to weld it........

no sh!t...:banana:

[tie6044]

What axle is it anyhow?

[MrClemons]

interesting! everyone have their own ways! LOL. but best of all.. detroit locker, but jesus christ they're expenisve! :bat:

air locker :D

[CountryBoy2784]

air locker.. hmm! which's better? this or detroit locker??

[89Orion]

I think the air locker is like a spool when engaged, but it's a LOT more than a detroit. Great choice for a front end though, since you can disengage it.

[CountryBoy2784]

yea yea, i have mini spool for front dana 44's but aint putting it in cuz the truck dnt have enough power, when i does.. im putting a damn spool IN! with 5:13 gears. instead of 4:09! with 38.5 boggers.. gonna rip the mud up!:poke: :D

[riverbasher]

My axles are 1 ton Dana 60's front and rear. My buddy still has the Corp 10 bolt rear on his blazer frame

[leadfoot]

this is just my two cents. but this is how i do it. i have had them break if i just glob them in but a old timmer told me to drain it clean. and heat the gears with a tortch then weld them. the guy that told me how. works at a diff. shop. i have had mine welded for 4 years and no problem. but i all so take all the slag out.its time comsuming,but wore it. the silicone idea is new to me but makes alot of sence.

[kxracer116]

I've always heard with heat comes brittleness and that ain't good.

[77fordf-150]

little booger welds won't do much good witrh big tires I'd think. Need some good solid welds in there not just some boogers thrown at it.

[mudtrux]

I'm a fan

I just cleaned mine really good with brake clean and welded the spiders to each other at there contact points. I can see where preheating the gears would be good idea.

[kxracer116]

Yeah i suppose boogers might just break off and cause problems

[MINN 55]

Big White Jeep Has The Right Idea It's Better To Pre-heat. Then Weld Because You Get Better Penetration With Your Weld

[kxracer116]

Doesn't too much heat cause brittleness?

[leadfoot]

just let the gears cool slow. and torch takes all the oil off and gives you alot better weld. only heat where you are going to weld. your gears are already harden steal.

[kxracer116]

That makes sense, thats a good idea and i'll try it when i weld my rear end.

[kxracer116]

Learn somethin new everyday!

[MINN 55]

Just Make Sure When You Heat It Up To Get It Cherry Red

[kxracer116]

Alright, i'll try that.

[MINN 55]

Well Did You Get That Rear End Welded Yet

[kxracer116]

I had 0 time, I took my lincoln through the mud and punctured a hole in the gas tank it it started pouring out, and i've been working on that

[SuperDirty]

After cleaning the gears or what ever you plan to weld warm it up the weld will penetrait better.

Then goe nuts weld that sucker silly

Wow, is that out of a Rockwell? That's freakin huge.

[SuperDirty]

Yep you should see how far a car squats when you put it in the trunk. I also would not reccommend moveing these around by yourself

That bottle encourages me to do alot of things, some not so smart.

[shakes_nig_rig]

aline the spider gears so u can weld the most of it together. and always preeheat them jist let them cool themselve DONT quench with water its quenshing that will make the gears britle. not the actual welding of them. most people are in a hurry to get stuf back together and they quench the gears which makes them britle and grenade on u. the idea of puting silicone around them will help keep ur ring and pinion alive or ur wormgear and ring alive for those of u with rockwells ha.

[mccaleb316]

or you can just put a spool in it.there cheap.

[MR. DODGE]

anybody have pictures that are not rockwells? i'd like to see more of the less stronger axles, i've heard of 1/2 tons lasting 5-8 years being welded and no problems at all!! this can't be true?

i have pieces of spider gears, because the pin broke in 3 pieces. i had someone weld it once, but it broke as soon as i backed off of the trailer, it looks like it can be saved. This time i'll let my Iron-working stepdad weld that sucker for permanency!

[leadfoot]

i dont have any pics but just make sure it is clean i use starting flued and then let it air out. and then i use a torch to heat them up. then you can weld. make sure you get all the flux out after.

[Bli1822001]

No heat doesn't make it brittle. Heat acrually helps strengthen the carbon. It's when you let it cool too fast that the carbon in the steel breaks down and causes porosity in the steel. That in turn makes it brittle. It's like heat treating something, you control the cooling of it so it doesn't cause porosity in the molecular structure on the carbon steel. Which for gears they use mild carbon steel so it would be more important to control the cooling. compared to a low carbon steel which wouldn't make too much of a differenct anyway.

[MR. DODGE]

i have an AC welder, so what's the best rod to use for the job? anything special or will 6011 work?

what are the best settings to weld at?

[MR. DODGE]

well, after a week of tinkering, we finally got that rear welded. the old welded spiders were only welded in a few spots so when one busted [from using wire feed] it got caught in the ring gear and ceased movement, which caused my slip-yoke ears to bust at the t-case.
this time, i got some cast iron rod and welded the piss out of rear and now i'm cleaning the slag and bb's out. if that don't hold then it's axle swapping time over the winter!!
