Also, I've watched every video from oldest to new and I'm pretty sure this is the first time you have ever mentioned your day job. Glad you have met in the middle between work and passion.
I really wouldn't weld on the axle shafts. You're removing the heat treating that the axles have by welding on them. Essentially bringing the metal up to annealing temperature and then as it normalizes and comes down in temp the heat treatment is no longer. Which part of the diff are you actually breaking? Stripping the splines out of the spiders? Or twisting off the axles?
Wes McWilliams I get what ur saying with annealing temp, but for his car making so much hp I can see why it makes sense to weld the splines so that the entire gear and shafts are one piece. Yes it might take away some heat treatment, but it's really only the spline area losing some strength, but then a crap ton of strength compensated by welding everything together. I'm curious however if the heat affects/melts at the diff seals?
Pawinning but that's where all the strength of the axles are it on the outermost layer. I also was curious about the diff seals. But people have been welding diffs for a while so I'm not too worried
Actualy in my opinion the best way to weld the diff is to go for tig spot welding the corners on spider gears and let it cool after every spot because after you heat too much spider gears they lose the strenght, ofcourse it's long process af, but worth going for... Never destroyed a diff. P.S. Apoligies for my grammar, but I think you got the point... P.S.S It's just my opinion
I grew up at a shop just like your brothers, so much cool stuff but being so little not knowing much of what any of it really was until it was gone. There was this pit named bubba that patrolled the shop n yard 24/7. Some asshole started cutting the chain link fence one night bubba ran em off I guess an went to get a piece. His shoulders were two wide he panicked n hung himself an the place was never the same to me
When I welded my diff I preheated for like 1 hour and the I put a tig root on the hubs and the spider s and then mig it all the way up but then I put it in a box of sand to let it cool down super slow so it does not make it steal brittle works every time I welded a 9 inch with 650 ls motor and it’s still going to so it must work.
Weld the back sides of the spider gears to their carrier stronger than plates but less work, doesn't matter you'll never need to take the spider gears out of their carrier anyway, saw you twisted the splines on the axle until it broke once even tho they are "hardened", I guess, still can be made out of better material or make new spider gears and axle ears with better material and a better spline profile then go through and have them case hardened shouldn't be any issues then lol but I'm sure something else will break😂 at some point it's worth going to a 9" or a winters tho personally my BMW just a street car but will probably put a 350z dif in as lsds are cheap and easy to come by have to mod the subframe but that's easy stuff
Welding a diff isn't an upgrade. Surely the time and effort invested at this point would have justified a 2-way... Also, wash the friggin oil out before you weld. You'll infinitely improve the weld strength.

That guy has one of the best set ups car and bike lifts wow nice shop
Damn mang, your bro is clearly an OG Metal Magician. Great info on the hardened steel too, I think a lot of us learned something here.
Your brother's shop is dope af. Great video as always
Congrats on 2k subs! 👏
i literally was thinkiing about having to weld my diff soon and this vid drops. thank you micah
I started having the same issues with my miata after I installed a cold air intake
🤣🤣🤣🤣🤣🤣🤣🤣
This vid was very informative, lots of useful concepts/methods! Thanks!
Neiman Darayand thanks!
I’m so glad to know I’m not the only one having these problems
FYI you can weld a bmw LSD, I have a welded 3.15 lsd in my e36, just have to die grind the inspection holes lager so you can weld them
Great video i just got 2 325i diffs im getting them welded here soon perfect info thanks for the knowledge
What about the axle seals? Shouldn't that damage the seals.
Wondering same thing?
question though. for that thick of metal, would your brther recall what settings he had his welder set to as far as voltage and wire speed??

do you use the 188 diff with the m3 outletshafts or a 210 m3 diff? thanks for showing too :)
If you burning the diff, it will be STRONGER? or why did you do that?
Thanks for sharing as you go man ! Btw... those hot rods and that Bike on the lift though !!!

From what e36 do you find the 3;91 diff?? cant find it anywhere.. any tips?.. i looked on a 325 automatic but that had like 3:15 someting..

other than the axle shafts, are there any other changes needed to run the m3 axles?
I’m hella confused ain’t the LSD used for drifting Micah keeps saying open differential.

Have the US M3 axles the same splines as the 328?
Can't you just chuck a mini spool in the diff?
so did this actually make it bulletproof? Seeing as you changed to a quickchange?
Nope didnt work with the dog box. It worked for the stock trans
@@MicahDiaz thanks for the answer dude, what model diff were you running there (might have missed it in the video)
Well how'd they turn out?
Great until I installed a dog box. Then I was spinning the output shafts
Right on! Hope my zf holds lol Thanks for the update!
Where could I purchase some hold fast merch??
Corey Pickles I'm setting up a website now should be up soon other wise hit my dms. On Ig. @micah_diaz_
Good info man.
Dude where the videos been?
I give it about two or three track days before these are POPPED 😂 next video "Diff broke again...7 series diff install!"
Sounds like you need a spool man!
noice, voice and music, couldnt understand a shit most of the time
Yo bro what happened to you????
lol @too much projects at same time xD
