Loud clunking/knocking noise from under armrest
Happy 4th of July!
Cayenne S 2005 @ 140K miles
Today for the first time I heard a very loud clunking noise from the armrest area only during acceleration. So I drove slowly (under 30 mph up to 3rd gear) to the nearby Porsche dealer (luckily only minutes away) and no more noise was heard.
The car will be diagnosed on Monday.
Meanwhile I did some search and it seems like the most probable cause may be a faulty drive shaft which was replaced once before under warranty.
Is there anything else that can be the culprit of such symptom?
TIA,
Sam

Not sure if you're familiar with the EPS center driveshaft bearing repair. It looks like it will save $$$

BTW the Q5, nice ride but I can' believe how retarded her joystick iWhatever is... OMG what is Audi thinking? I rather have no technology than 20 buttons and a joystick to use the radio.

Most manufacturers produce very little of the vehicle. They specify a design for some of the parts and have it manufactured elseware and just assemble the parts, some parts are off the shelf parts that are shared. OEM refers to the manufacturers that build the parts for the Porsche in this case. For the driveline I think Lobro is the manufacturer. For much of the suspension it is Meyle, brakes Brembo, Pagid, etc... You can save money by getting the parts without the Porsche stamp but sometimes you can only get the equal quality OEM part by going through a dealer.

This explains why OE and OEM aren't necessarily the same thing either. There are OEM brands that aren't necessarily the parts that were on your car when it came new from the factory (OE).

To ensure uninterrupted supply and keep good suppliers happy, mfrs will sometimes source the same item from 2 or more OEMs. Tires are an obvious example.

Since were expanding on this I'll throw this out too. Since the Cayenne is partially built on the same assembly line as the VW Touareg and Audi Q7 it shares many of the same parts. Many Cayenne parts will have VW part #'s on them and are interchangeable to include electrical modules which can be found new or used much cheaper if you search for them by the VW part rather than as a Porsche part. It would be great if we knew in one list all of the parts that are interchangeable.

Yup it is the center bearing securing the drive shaft. He says they can't just replace the bearing so full replacement is in orderas I predicted.
Cost------> Only $2300.
Ouch!

I have known the service person for about 10 years so...but the difference in cost is huge.
Update: The drive shaft+bearing unit is about $1750, and $400 in labor + misc.
