Delrin drive shaft support

[JShadzi at aol.com]

   Well, let me address your questions...first off, yes, delrin will introduce a slight amount of noise and vibration, but not much as I can attest to the prototype we did on a V8 quattro.  Infact, with the reduced driveshaft slop, the car actually feels smoother, especially during throttle transients.  Everyting is a compromise, use rubber and you are very isolated from vibraiton, but then you have to put up with excess deflection and reduced longevity, something the delrin solves in both respects.
  As far as the Mercedes part, it should replace the the stock rubber piece fine as long as the bracket is modified accordingly...I don't agree with epoxy, it won't last a mile IMO.  It also sounds like a lot of work IMO, what I am proposing will use the stock bracket, the delrin piece fits inside the stock hollowed out bracket-no cutting or welding, a job that can be accomplished by anyone using a drill and common hand tools.  
   I hope I answered your questions, the decision is yours to make  =)

<< 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?
