U-joints
 

Does anyone know of a source for replacement u-joints for M-B? So far, everyone says you have to buy a whole new driveshaft from the dealer, or get a good used one.

Guess you figure all Benz u-joints are the same ????

Actually they are, except for some oldie but goodies, the same in that they are not replacable by the owner.

..but with no info, we do not know that , do we???

The point being, " How about a model/yr Please..then we would be more than happy to try and help..

Well, that should have been your question to the OP, not me.

Yeah..
My question was to OP , but you answered it .
The question was never directed to you, the explaination was.

You mean this question, which was not directed to the OP. Or another question?

Get off it , Charles..
You know what I meant ...and I for one would not give an answer to a part question w/o a model/yr.....be pretty foolish if the guy happened to answer back that he had a 108 chassis , now wouldn't it???

Yep, so why not just ask that instead of being cute?

circledstar,

you can readily find u-joints for MBZs but the issue is the way they're installed; they're peined into the shaft unlike most other driveshafts which are usually pressed in and held in place by circlips or caps. IMO changing these is best left to a driveshaft specialist.

Being Cute ...that's great..

Ok , Charles ..I should have asked that instead of being cute ..
..but next time a post comes up and the guy actually expects some kind of a technical answer without having the sense to list model and year, I guess I am just going to be cute again.. guess it is just a pet pieve I have..
Maybe I have been here too long and seen too many of them, so I will give that to ya..
Now, I have a desk full of schematics and code charts in front of me, so if you don't mind, I will leave it there.
Thank You..

Anyways, I know that, if the case involves a w123, there is a listing with partsamerica (advanced auto), so there HAS to be an aftermarket solution. If you search around here, you should find a thread on this (probably hasn't been posted to in a couple of years). There's a few members here that swear an 80's Ford Falcon uses the same joint, but I can't confirm that. Also, in the case of the driveshaft, the u-joint is servicable, you just have a lot of work to do to get it out. Apparently, mercedes has welded caps over the ends of the joint, sealing it into the ds. The solution lies in a dremel tool, and a BFH (big f'in hammer). Good luck, and if you come to any conclusions, please share your experience.

Many modern driveshafts use a staked in u-joint. Getting them apart is not hard. Re-assembly without the machinery to re-stake the joint is impossible.
Some driveline shops now have such machinery or they replace the yoke(s) with one that accepts the older retaining ring type of joint.
A google seach for driveline service will turn up a number of choices.
