Is my TT finally giving up? Answer: Yes.

We designed the Super Bearings to negate the need for the problem prone vibe dampener. It's also not just the weight that helps to do so.
This was our "kill a few birds with one stone" approach to rebuilding the TT.
So far no complaints.
Cheers,

The dampers are typically installed to 'dampen' a ringing or resonant vibration. Kind of like the crankshaft harmonic balancer "dampener", this is a torsional (twisting motion) dampener. The ringing in the shaft can be eliminated by adding a rotating mass in a rubber sleeve (as this and the harmonic balancer are), or by putting dampened support at specifoc nodal locations on the shaft, as Constantine's Super Bearings are intended to do.
I would venture the opinion that the TT damper could equally well have been placed on the outside of the TT had there been room for it. It's placement and weight suggests to me that it is to dampen the vibrations of the engine TT transaxle combo as one unit.

Charlie if you go back and read the TSB that Bill posted your question will be answered.
Dcrasta you too should read the TSB as it has info that you might like to see

"A dampener is someone or something that dampens. So damper and dampener can both mean one that deadens sound vibrations."
Either is correct.

Charley helped me get the TT apart. He suggested a bottle jack, which I had. We braced one end of the TT against a post and the bottle jack against a second post and pushed the shaft out in short order. I won't be back on this until Wednesday morning.

Maybe I can't read, but it says " So damper and dampener can both mean one that deadens sound vibrations."

I retrofitted a good (smooth) used unit for my bad one. I still have the old torque tube to rebuild but so far I got off 'cheap' .

Ok.. 88S4, Automatic.
I have a 928Intl supplied rebuild TT that was installed Dec 20th last year. All new TC bearings, the whole WYAIT shebang was done. Was quite expensive.
The car has a 'out of balance' feeling vibration at all throttle settings, cruise, neutral, parked..etc, and peaks out at about 3000rpm.
Could I have a bad damper on my TT shaft that needs replaced?
