Delrin drive shaft support

[S. Jaworski]

Javad,

Let me see if I understand what you are trying to do.
1. You want to replace the center bearing bracket rubber mount with a Delrin
part.
2. You fasten this Delrin part to the center bearing bracket . . . using
nuts and bolts I assume? I assume you need to grind off the welds on the old
center bearing support?
3. Then you will install a readily available bearing to the center of this
Delrin part. How will it be secured? Press fit?
4. Then you will press the bearing center onto the drive shaft . . I assume
you will need to remove that dust shield off the drive shaft. Same procedure
that Blau tells you to do when you buy their center bracket?

Is my analysis correct?

I think that the solid mounting will introduce some obvious noise into the
passenger compartment . . no?
Have you actually tested this assembly in a car and checked for noise?

A couple of weeks ago, I did some research in the audi archives and got some
info on MB parts that may work on the audi.

I recently purchased a center support bearing by Mercedes Benz P/n 123 410
10 81. This part is made by Weyle of Germany. There is a part number cast
into the bearing support ring - Meyle 014 041 0045
The bearing is also an MB part made by Weyle of Germany P/N 014 098 0017.
Parts were purchased thru RPM Foreign Auto Parts, Stanhope, NJ
973-448-0440

I think both parts cost me about $50 . . . I dont have the bill to check
against.

Now the bracket from MB isn't the same as the Audi bracket. But, it looks
like that audi bearing support is only welded in two spots to its bracket.
It looks like it may be possible to grind off the welds. Then place the old
bracket on top of the MB bracket(plenty of room and diameters are close),
and tack weld it in two spots. Voila!  Its done.

I'm not sure if the MB flanges will interfere with anything . . they may
have to be ground off.

Best of all, you dont need any skilled labor to do it. The hardest part is
the welding . . but, two spot welds should'nt cost that much. Actually, you
might be able to epoxy the MB bracket to the Audi bracket. Some super duper
epoxy might work. Kind of risky . .if it lets go, the drive shaft will flop
around there . . .you wont be able to drive. There is enough room on the
brackets to think up of some mechanical fastening system if you cant get to
a welder.

Mind you, I havent tried this out yet. But, it sure looks feasible when
looking at the parts on my desk.

I would give this a try before going the Delrin route.
