center bearing info for newbie
Hey Newbie...I missed your original post and don't have your address...here
is 'the center bearing post' from my files, containing the BMW part # for a
center bearing. I think it is probably the one you need, but I'm not sure.
You could post Mr.Lawson or Mr. Rudack and ask them for help. Mr Rudack
appears to have been working on a 1988 model 90 Quattro.Someone should
reply to you. Try these addresses:
<dlawson@digitalglobe.com> <rudack@ucsub.Colorado.EDU>
I never did this repair. I just kept the file. The Rudack post and one by
Craig Porter follow this little note. Page down! And...Apologies to the
list for burning up the bw.

That bearing is a pain in the ass! I tried with the help of fellow
Q-listers to find a replacement bearing. There is one made by Torrington
but I couldn't use it. I needed a new drive shaft. Then, I received my
Blaufergnugen brochure. It saved me!
Rebuilt drive shafts are only $200.00! The shipping is painful in itself,
but you save a hell of a lot of money ;-) Craig K. Porter

Well folks, about a month after my poor baby broke it is all together
again. With the help of Steve B. Bruce B. and Graydon S. my 90Q is running
again with about $50 dollars of parts. I rebuilt my center drive-shaft
(carrier bearing and u-joint only). The bearing was gotten through GPR and
is BMW part# 26121209532. It is the bearing including the rubber surround
and the mounting bracket as one piece, total cost $35.
I successfully removed the bolt which holds the yoke to the foreshaft with
a 17mm box end(this required removing the zerk grease fitting from u-joint)
but found it too difficult to get the yoke off(no way to
press/pry/hammer/pull etc.). With Graydon's help I took apart the u-joint
and discovered it to be fairly "trashed" and stiff. The only u-joint I
could find locally was a non-greasable unit made by Borg-Warner($15). If
anyone
has a part # for a greasable u-joint please let me know for future
reference. After re-assembling everything I cleaned out the CV's,
regreased them and installed on the car. I sort of assumed that the
drive-shaft would self-align and it did! The car runs great. All in all it
was a simple procedure, just a pain to get the necessary parts.
