The TRUE/FALSE of Thrust Bearing Failure
Okay to get some things straight about thrust bearing failure (yet again) or TBF. Please read below:
1. Thrust Bearing Failure is Possible on 928s.
-True
2. Thrust Bearing Failure happens on ALL 928s.
-False
3. There is a chance TBF will happen on a 928 that has had the torque tube replaced if torquing procedures of the pinch collar weren't adhered to.
-True
4. It takes 1-2 hours depending on how slow, drunk, lazy, tired, or any other chronic or hypochondric condition you are in to check and release the end play of the flex plate by dropping the exhaust and belly pans ONCE A YEAR.
-True
5. There is way too much SCARE about thrust bearing failure on 928s in this forum.
TRUE, TRUE, and TRUE.
Thank you for reading

The ONLY 5 speed I know to have thrust bearing failure was one of Mark's race engines with an aftermarket clutch which made it possible to out too much pressure on the bearing. The early auto torque tubes had a snap ring and shims on the end which prevented the flex plate collar from sliding but Porsche discontinued this practice and then we began to see such failures ...and we hear about a several every year. But we have 50,000 + contacts in our data base between owners, shops, dealers etc....little happens that we do not hear about !

Yes, but not all...so kind of true

-False
See question 1...you kind of answered your own question before you asked it.

-True
That could be said for ANY procedure on ANY car in the world

-True
FALSE. You cannot foresee WHAT kind of issues you may encounter on ANY procedure done on ANY car. In directly addressing the coupling, providing the correct tools are being used, a lift or not, no seized nuts/bolts,and a slew of other probables, this job could take from 30 minutes to who the hell knows when.

Only because of posts such as this when someone gets on this board in either an uneducated state or after sniffing Brake Kleen too long...or what ever your poison is.

You ever live it? IMO, tbf is something real easy to hide. people need to be aware of it. my 89 after the pressure was released the car ran fine, but was out of spec 4X.... I could have kept my mouth shut played dumb and sold the car. Also too many people do not check for it annually.. I think the posts about it are a good thing.
