Cardan Drive Shaft - Bullet Proof Version
 

Porsche Cayenne Cardan Drive Shaft Assembly Rear : Genuine Porsche - Rebuilt HD

This is another good core unit that has been rebuilt to Turbo Kraft specifications. The original unit was removed from a in shop project Porsche Cayenne experiencing the all to common shutter at lower speed acceleration. We had seen several customers with clunking, vibration and metallic grinding symptoms originating from the rear drive shafts so we decided to "UPDATE" these units with larger and stronger parts. Porsche has updated units with superceded part numbers 955 421 020 21 but are expensive and not built to last. We have had great success with huge savings to that of Porsche. The unit we offer is ready to ship and install.

What makes these different?

We utilize a heavy duty carrier bearing which is much stronger than the OEM bearings.
The CV at the rear is reinforced
The carrier diaphragm is much thicker than stock.
High speed balanced to a finer resolution than OEM specifications.
Guarenteed fit and function.
Save money upfront and in the future with a longer lasting part.

You said "dudy"...tee hee hee

Thanks for pointing that out. Duty (Updated)

This must be a common failure! :mad: As we just changed ours at the dealer because it wouldn't go over 45 without vibrating the crap outta ya. Had to have it towed. I'm not confident with this Cayenne S so we don't take it far.... :( This is my wife's car and I wish she would have picked the Land Cruiser she drove over this! I know why, because that's what I want... LOL! ;)

You really shouldnt feel insecure about driving your Cayenne. They are very reliable vehicles. Any car is going to have some common problems, Land Cruisers are no exception. You said you have replaced the cardan shaft allready- so as long as the ignition coils have been updated...you should have no problems!!

Yeah right! Since that we are now having the PSM workshop failure. Took it in and it's the awd control box. Just another $800 out the door. The warning went off but we'll probably fix it when it comes back on. We've had this car less then a year and have had to put about $2500 in repairs. Not even routine stuff, repairs. I've had the routine stuff too, tires, alignment, oil change.

Not the cars fault but it's been in the body shop three times because it's been damaged in parking lots. It currently has a big dent and scrap from another parking lot damage. It'll go back in in the Spring. It's a magnet for damage...

Anyways, that 2500 is WAY more in one year than I've had total on my 12yr old toyota 4Runner. I don't see us keeping it to long and it will be the next vehicle replaced when it comes time. Only thing is the wife just wants another one. Oh well.... Oh, and she doesn't trust it either because when she works out of town or we take any trips my Toyota is taken. Hopefully the next one we have better luck with...

Wow, sorry to hear about all of your troubles. Sounds like a lemon. I think I would feel the same way if I went trough all that.

Funny thing though- I bought a used 4runner about 6 years ago it had some noise in the rear end. The seller told me that the rear 3rd member needed rebuilding. so I brought it to a shop and had them rebuild it. I picked it up and drove it, same noise. I took it to another shop and i was told that the driveshaft was bad. I had them replace that. Long story short...I spent the next few weeks of my free time replacing the transmission myself.

I put about 2,000 miles on the truck before throwing a rod through the block. I sold it for $300 just to get it away from me because I was so sick of it!

I still love Toyotas, I just think the scumbag that sold it to me really beat the crap out of it and knew it was about to go before taking me for all i had at the time. Another life lesson learned the hard way

Does anyone know where/how to probe to pin-point the problem?

What do you mean by "pin-point the problem"?
Diagnose? Symptoms?
If you have a bad one, it's usually really obvious: it clunks and vibrates badly, often at specific speeds. It can sound and feel like the drive shaft is about to come ripping up through the center tunnel.
Why didn't Porsche/VW/AUdi use a stronger carrier bearing? Probably NVH. Look at an F-250 truck and the carrier bearing is solidly mounted. That transmits noise and vibrations through the chassis, but on a (commercial) truck like that they don't care about NVH like on a luxury SUV.
Are these a known problem on the Cayenne/Toureg/Q7? Absolutely. Our local Porsche dealership has little or no inventory on a lot of common repair parts, but they always stock 5 cardan shafts. That pretty much says it all to me.
