[W126 Coupe] Rear End Thumping

[Alexander Hochhausl]

..the 516 area code is my cell phone from the old days before they were
kind enough to create the new 631 area code (so I and many others had to
reprint business cards, etc). I actually live in Suffolk.
 
Thank You,

To tell you the truth I really don't remember - probably aftermarket. I
have the receipt, but am too lazy to go dig it out:)
 
I'm looking for the mount and bearing - might as well do both. How much
will that run me & can I have them before next week end? Do you take
credit card or paypal? It's an '89 SEC 560.
 
Thanks.

Did you use genuine or aftermarket?  AM rubber bits don't hold up as 
well IME.
 
As markus mentioned, I can get you what you need..:)

... or so I thought.
 
This may help others. 
 
Over the past few months I heard a thumping coming from the rear every
time I accelerated from a stop (slow or fast - didn't matter) for ~ 2
seconds. Sounded to me like muffler hitting the body.
 
I found out it's the center bearing carrier - the rubber is ripped
apart. So I guess when I start out it bounces around in what's left of
the housing until the increasing rotational inertia causes it to
stabilize (like a spinning top). Odd thing is I had no high speed
vibrations. The bearing is located pretty far back, which made it
    
sound
  
like the sound was coming from the rear end. I'm glad it's only a $20
problem.
 
The mystery is that I replaced the driveshaft ~ 3 years ago, and also
replaced the carrier (bearing and flex disks - since I was putting the
supercharger in - I wanted no weak links), so I don't know why it's
ripped to shreds already. The supercharger really should have no
    
effect
  
on the carrier.
 
Has anyone else experienced a short life of this part? Maybe I got a
cheap/defective part last time? Can anyone recommend a good source for
this part, cause I'm not looking forward to repeating the labor in
another 3 years.
 
On my 380SLC I had fabricated a solid rubber carrier vs. the thin
    
stock
  
one & that lasted for ever, but I really don't want to spend the time
doing that again.
 
Thanks All.
