ujoints

[Burning2nd]

are the u joints on the drive shafts replaceable?

when i drop the exshaust and heat shield for the drive shaft center bearing replacement,

i would like to replace the ujoints

are they all the same... will my local NAPA carry them?

The u-joints on a BMW drive shaft are not field replaceable. They'll be welded or staked in and will require machining as a part of the replacement.

has anyone here with the know how performed this procedure before. Cause im wondering about this too. I dont think that i could afford a driveshaft and this would be at least worth trying.

They're only held in with tack welds about 6-8 welds on each cap. You should be able to just cut the welds and pop the caps out and then replace the u-joints and then make some tack welds on the caps. Only issue I would say ould possibly be re-balancing the driveshaft but I even doubt that for when I replace U-jointson driveshafts at work none ever need re-balancing.

So it is DIY just not as simple as removing a S-clip and removing the caps etc..

I bought mine from Mesa Performance in California. Replacement driveshaft, with u-joints that DONT require greasing - for like $350 after core return. Not bad, I don't think!

We use a company that rebuilds driveshafts. Costs $300-$350.

ok but has anyone actually tried to do this i might try but i dont even know where to begin with figuring out the size of the u-joints

I wouldn't reccommend it. BMW has these made to where they are not serviceable. I'd just get a rebuilt one from Mesa or Driveline Service of Portland.

Last time I remember I thought I saw www.autohausaz.com carried them for $20 each

If you can tack weld you can tackle this.
