[s-cars] S6 driveshaft R&R question

[Ray Tomlinson]

Rokas,

The center u-joint is non-serviceable on the UrS4/6 - it is staked in.  You
can, however, remove the front portion of the shaft from the u-joint and
replace the bearing, but you will need a MAPP torch to separate the splined
gear from the u-joint.

List wisdom dictates that the center rubber carrier may be replaced with a
unit from a MBZ, but that you need to fabricate/modify the bracket.  I
purchased the MBZ unit, but found that the rubber surround was of a lesser
durometer than the OE Audi unit, and did not want the added play, despite
the fact that my center rubber surround had some miles on it.

If you do not have the Audi alignment tool to remove, be sure to index the
joints on both diffs, and mark carefully the position of the center carrier
bearing, otherwise, an out-of-alignment center prop shaft will vibrate and
without a doubt will shorten the service life of both end CV's, the center
u-joint, and possibly more.

Be sure to repack completely your driveshaft CV joints, and clean up any
mess.

Ray

Hey everyone. Can anybody who has ever r&r'ed an S4/S6 center driveshaft
chime in on this question: I am almost ready to begin r&r'ing mine and I
need to know what to do about a loose u-joint. I gather the one in my car is
replaceable but with what? If not, what did you guys do to it? Thanks a
bunch,

Rokas
