HOW TO WELD A DIFF WITHOUT DAMAGING IT / BUDGET DRIFT MODS

- In this video I'm showing you how I go about welding a differential making sure not to cause any damage to the crown wheel, pinion and bearings . I'm using mild steel mig which is not the best option for welding dissimilar metals but its gonna get the job done!
Weld spatter in the gears and bearings will cause your diff to start whining and grinding shortly after welding it solid. Here's a few tricks to stop that happening to you.
My names Matt Urch and I own and run Urchfab welding and fabrication.
I specialise in custom automotive fabrication from building roll cages to complete one off builds.
I built the worlds most unique and oldest drift car known as the drift rod which can be found on my channel.
So if your into grinding, welding, fabricating, drifting, going fast etc, your in the right place!

*NON*-chlorinated brake cleaner is the stuff needed for upcoming welding jobs
otherwise you get *chlorine gas*
TIP - from one who has built many of these for competition : As you mentioned 10:36 make a block of steel to drop in between the spider / side gear. Make sure it is a snug fit prior to welding. WHY? When you weld the gears up they will distort / pull in which can over a fairly short period of time cause axle spline issues. I have used this method for some high hp applications without failure.
That's a good tip, Thanks
Great vids - very informative . keep up the good work!!
literbikedoc I'm not being rude or anything dude just asking but if you build your own and tell this guy what he should do or would work better why do you watch these vids if you already know?? Is it just that you have so much interest in it or you trying to find some other cool tips or tricks you could improve for your self or what??
literbikedoc and other thing do you drag race or what?
@@brendinweber5229 it's helpful for people who haven't done this before to read extra tips in the comments
Best diff welding vid I've seen mate! Well done. Most wont tell you that you cam weld the gears to the cast housing.
Was waiting for you to mention the plate method! It comes in handy when you can’t get access to the tight corners or the gear - case.
Also, cutting out a half circle of steel to clamp over the crown wheel is easy to make and great splatter insurance 👍
This is the most comprehensive video on how to weld up an open diff on youtube that I've come across. Very thorough. Thanks 👍
Ive been watching alot of videos on how to weld a diff and this one is by far the best and most thorough, good job man !
Enjoyed. Thanks for going into detail and showing the various options and what to look out for.
This channel is so underrated! - Great stuff mate! Congrats!
Thanks
That diff is adorable. I hope it grows up to be big and strong. 😆 just playing.
Thanks for the content, well described, well done video.
Rob here... If you put some tip dip on a small brush and brush it on areas that have a potential to collect spatter you can greatly reduce or eliminate the spatter from collecting in those areas.
best way ive found is to cut a 3/16" plate to fit in the center of spider gears and weld it to all four gears. for good measure you can weld it to the case as well but not necessary. Been running the same welded diff in my drift car for some 12 years now no issues
Welded diffs are great until your car breaks down and you need to push your car around a corner lol :(
Thats true!
ik im late but would this be a problem with lsds as well?
@@benzo1383 no because an lsd only locks up when high torque is applied
Don't plan for failure lol
So much helpful information thankyou so mich
Great teacher.
So in a simplified form weld everything inside the housing except the bearings and axles of course??
Is it ok to do all these welds if possible?
I saw one where they pored lead in ,and you can melt it back out if you want
Thank you...
what weld wire did u use?
Thanks!
Can this be done with a 130 amp welder? Or do I need to pay someone with a more powerful welder to do it? If my 130 will do it, should I use mig, or flux core? Thanks! Very good vid.
Can I change my ring gear when it’s welded already
heat soak if welded in the housing will stuff the gears, pull it out , pull it apart clean , prepare and weld ,
If you have C clip axles do not weld the spider shaft or you won't be able the clip the axles in .
Thanks for the great advice mate. My question (not trolling) is: if the brake cleaner residue can give toxic fumes when welding, how does it help to burn it off beforehand with a torch? Isn't that the same result?
How would I go about picking a voltage for this? It's not really something I can put the gauge up to and go OK it's this thick and read the chart.
You just have to make a guess based on what areas you trying to weld Bud . sorry I can tell that's probably not much help.
The best thing you could do is grab some junk cast iron some 1/8 and some 1/4 inch steel and find a setting where you're able to weld any of the 3 to each other (with as little spatter as possible) by controlling your hand movements. It is possible if your a good welder you just will need to be aware of where your putting heat
if you weld to that center shaft you wont be able to replace an axle if you break one will you
How do you get your axles in and out? Probably shouldn't have welded it to the cross shaft
James Kobus the cross shaft won’t affect the axles coming in or out unless you snap your axle at the spline, in which case she’s a new diff job
How are u going to put your c clips in if shaft is welded? What was the whole point of taking it out and welding it?I don’t get it
I wonder how my front wheel drive car will handle on gravel if I do this
Spider gears, axle shaft, housing, spider gear cross pin... Figured I'd give you the name of some parts you may have forgotten
Why did u weld the middle shaft? How are the c clips going to go in?funny shit
you shouldnt weld to the housing its cast iron.
Looks like forged steel to me
Not supposed to weld the gears to the case itself are you ?
You do know that welding it is damaging it.
Case is cast, gear is hardened alloy steel, you are making problems with your process.
Case looks like forged steel to me. Filing it will confirm. Also you'll notice the word "budget" is in the title
Any Chlorinated brake parts cleaner is a big no no. Chlorinated parts cleaner when exposed to U.V radiation from welding can degrade into Phosgene gas. Phosgene is a neurotoxin the damage is cumulative and irreversible. It is also a bad idea to weld to the center pin because some diffs have to have the center pin removed to slide the axles in to remove the c-clips so that the axles can be removed. This is a job where preheat is necessary, you have hardened gears welded to cast steel and hardened gears. This is a job for 7018 stick or E71-T1 wire either way low-hydrogen welds are the best choice for this type of work. It is also a good idea to weld these on a heavy steel bench then warm the parts back up then cover with a metal bucket to slow the cooling rate. I build these lincoln locker diffs for pulling trucks with engines in excess of 1000Hp. I am advising people this video is pure bullshit! When a chip if that hard steel comes off and runs through a bearing it will be all over but the crying. This is not a mig job and to act like it is is irresponsible to the point of criminal. Epic fail on this video.
Where's your channel to see how you do it champ??
No! you'd rather flame someone giving it a go. He did preheat with flame to remove residue and to heat parts. All i see on your channel is dancing....must be a great welder!!!
Mick Holgate I don't need one. I just gave some simple instructions and highlighted how what was done here was wrong. Do you need me to set the welder for you and hold the stinger while you weld it? I don't really care if someone does a crap job, my first and most important point was about safety. I don't want to see anyone get sick or dead over trying to save a few bucks.
Mick Holgate My videos are of what is most important to me being my children. I don't need to get on youtube with welding videos to try and impress non-welders with my skill. I validate myself with the results I yield everyday. If I want to polish something it will be my diplomas from HIWT or my nuclear certifications or my steam certifications or at lowest my structural certifications. Do yourself a solid and fuck off everyone who takes me on here loses save yourself the shame.
tdej80 I’m not taking anyone on here. Just stating fact that you sound like an absolute flog based on your assertions! There’s a right and wrong way to go about instructing and commenting.
Didn’t your parents teach you the saying “if you have nothing nice to say, say nothing?”
