could this be from welded center diff+street car?

i just keep breaking axles, all rear axles, both drivers and passengers, i think its from the stress of everyday driving and the welded center diff. what do you think?

Doubt it. Much more likely you've been launching the car too much and too hard. A welded center can send up to 100% of the available torque to the rears. No way OE axles will stand for that. Heck, people snap rear axles with a 35/65 center and a t25.

I had a bad experience with breaking axels in my 90. Always the rear passenger side and not even launching. I broke one just pulling away from a buddies house like normal. I Got mad and changed to a 4-bolt from a 92 and never broke another axle. I think something was wrong with my old diff?

this problem started occuring whenever i welded the center differential, i have had countless hard and violant launches before the welded center diff.

and they all break in the same are is this a weak spot in the axle? right before the splines?

 

[oztofrdm]

I have never broken a rear axle(Knock on wood) but yes, that is the weak link on the rear axle

 

[TurboAnything]

Yes very much so its the area of least material from them cutting the splines in.

It is unwise to drive on the street with a welded center diff…

It isn’t the smartest thing to engage into any type of launching with a 3-bolt rear end (people have known about the superiority of 4-bolt rear ends since around 1995).

But it is completely INSANE to drive around/launch a 3-bolt rear end AND a welded center diff! The only thing that is missing from the above equation (if your goal is to build an ultimate rear axle killer), is a solid hub/pucked clutch disk and Nitto drag radial on a cool night .

No one, who is interested into any type of launching, should be running around on a 3 bolt rear end. 4-bolt rears are now selling in the $250-$300, so there is no excuse not to upgrade!

You also shouldn’t be running a welded center diff on the street, but that is more of a personal choice. If you can live with a car that handles like crap, then more power to you . Just do NOT do it on a 3-bolt rear. And expect to see more transfer case problems

see the thing is i have 20 or more timeslips at home with 1.7-1.9 60's all of them on the 3 botl rear end on the stock center diff and it wasnt until the center diff being welded until i encountered these axle problems, and i drive my car around everyday or i did until my liscence was suspended. i admit it is rather annoying and i should have never welded my center diff but my dad is a tranmission specialist so everytime i break something it gets fixed easily and quickly its just a pain to tow the car home then to the shop then get all the fragments of shattered axle out of the carrier bearing. and ive just about run out of spare axles now.

You are getting much more torque to the rear wheels with the welded diff, then you were with the stock viscous diff. Also you don't have any suspension mods listed, if you are still on your stock suspension you are transferring alot of weight the rear end of the car putting even more stress on the rear axles.

When I broke my 3 bolt it was from adjusting my rear shocks softer to eliminate wheel spin. With out the wheel spin the passenger rear axle snapped. If you are on the stock suspension your rear is even softer.

It sounds like you knew what was causing this problem before you even posted this thread. Just fix the problem and be done with it.
