T2,

From an earlier thread-

dtakenname,

From what I remember on one end of the shaft is a rubberized flange that was found during a routine service visit to have cracks in it - there was not any obvious sound or anything else to tell me it was cracked - a good mechanic found it and we replaced it.

Now on my wifes Cayenne when the cardan shaft was about to go there was a thud thud thud under acceleration you could hear (as if a shaft was out of round and rubbing against the undercarriage). It also did not fail but was darn close to failing when it was replaced.

In either case it was a simple repair from a lift from what I have seen when I've been under either vehicle.

Also, you said "cardan (intermediate) shaft" was replaced in the thread above. Not sure what that means.

Sounds like they replaced the shaft or bearings that the shaft rides on?

Thanks!

 

amazing! awesome to see a post like this!

 

Paulunm,

Ahh got cha.

The RMS and bearings are different than the cardan "intermediate" shaft.

The cardan shaft is a known fail point on the Cayenne's. During a routine service the belly pans were pulled off to inspect running gear underneath the car. From the front of the tranny to the font differential I think the shaft is in two or three pieces. The one with a hard rubber mating flange (the cardan shaft) had some cracks in the hard rubber so we replaced the shaft. I suspect the hard rubber flange is there as an intended fail point in the event that the front diff or the tranny get locked up so the boot will break free and not damage both - pure speculation on my part though.

That makes sense now...

Now, which bearings did you replace? Were they the intermediate shaft bearings?

 

Wow!!! I will never sell my car....congrats!!!!

 

Paulunm,

The two bearings were in the clutch ***'y - one was the pilot bearing for the clutch and I am not sure what the other bearing was but was part of the clutch, flywheel, pressure plate ***'y. I have nto done any intermediate shaft bearings.

The other aspect that is not mentioned here is that Tom's car still looks near new. I see it every spring in a rally we do and the paint condition is remarkable. Tom, are you on for 2010 spring rally?

 

thats pretty damn cool....has Porsche been notified of such a high mileage car with still so many stock parts?

 

John,

I'll be there. See you then.

Holy hell, that's a milestone! I'm just shy of 27k.

 

My infant only has 21,000 miles so looking forward to a long life. Congrats Tom on having a great car.

 

I will testify that T2 drives the wheels off that thing! I am embarrassed in his company

 

Agreed! I don't mind when Tom is in our group during the rally.

 

Way to go bud!

These are looking to be as durable as a Cummins diesel....

 

My car is at 55k now (bought at 48k) and the major service is being performed as we speak. Tim, my mechanic, pulled the plugs and said that they are the original Beru plugs that came from the factory in `02 and even now look clean enough to last for awhile longer (went to Bosch FR6LDC). Diverters are being swapped out even though they are 8 years old and hold 1.0bar of boost no problem. Rotors look factory as well (not completely sure though), and they are still within spec. Turbos look fairly clean as well. The only real issues that were identified were worn e-brake shoes and a worn tiptronic transmission mount, which is being replaced with the 997 turbo part.

There was a black `02 turbo tip exactly like mine at the shop with 150k miles on it. It was pretty dang clean for a 150k car. Tim said that the only "major" work that he has done to the car was a tranny rebuild at 140k, and that was likely a bit premature (because it looked like the car did ~50k with a broken trans mount).

He basically stated that if I don't drive like a demon (lol), I could make it to 100k without anything other than routine maint, and that the car should easily hold up well past that. Not bad for a 12 second all day long, all season DD, IMO.
