Therefore, I felt uncomfortable trying to use the aftermarket guibo, and opted to replace the entire shaft.

I just felt using the aftermarket guibo may have been unsafe, and led to greater issues.
Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

The rubber "Guibo" on my cardan shaft is cracked. It's recommended to replace. However, you can't just replace that one part. It requires a whole new shaft. Does anyone know if the "Guibo" off of a Cayenne will work. It seems Porsche sells that part separately for the Cayanne, but not the Carrera. Below is a link which provides a visual of the rubber "Guibo". They look identical. But the measurements may be different. I've tried calling a few dealerships and they haven't been able to confirm weather it will work or not. Any advice is appreciated. Thanks.

Dan, you're my hero.
I just ordered one from the website provided by MPD425, above. I actually ordered a new cardan shaft earlier today before reading your post. If the guibo you recommended works, I'll be returning the new cardan shaft.
I'll keep you guys posted and let you know how it works. Hopefully this is teh answer for all of us C4S owners. Thanks again for your help.
MPD425, thanks a lot for the link. I ordered one of their site.
I attempted to install the aftermarket guibo on my cardan shaft, instead of having to replace the whole shaft. Unfortunately, the guibo wasn't compatible (at least to my liking). See pics below. Basically the aftermarket guibo I ordered looked identical to the OEM guibo....same shape, circumference, holes lined up, etc. However, upon closer examination, the aftermarket guibo was a bit thicker. More importantly, the metal locator sleeves inside the guibo were flush with the guibo itself. On the OEM guibo, the metal sleeves stick out farther than the guibo itself. They act as locators when fitting to the cardan shaft, as well as holding it in place. The cardan shaft actually has 3 counter sunk holes for these locators. Therefore, I felt uncomfortable trying to use the aftermarket guibo, and opted to replace the entire shaft. See pics below. They are pretty much self explanatory. I do appreciate all of the help and advice from fellow members. I just felt using the aftermarket guibo may have been unsafe, and led to greater issues.
In the pics, the OEM guibo is on the right. The aftermarket guibo is on the left.
Yes, the aftermarket part was BMW. It's possible another BMW guibo may work. But I already had the new cardan shaft on hand and needed to get my car back on the road.
I didn't see a part # on the Porsche part.
Sorry, nothing positive to report, according to my mechanic it doesn't fit, the holes are off spec. He did recommend me a 2WD conversion instead of buying a new shaft ;-).
I wish there were an index of all guibos so that we could find one that fits...I d'ont fancy spending 600$ on a new shaft when I just need a flex disc
Sorry to hear that. Yes, an index of guibos would be nice. I think I paid $490 for my cardan shaft through Sunset Porsche [phone removed]. Good luck with the 2WD conversion. I've heard several people doing that.
Resurrecting this thread....
I am replacing mine in the next day or so. 2003 C4S with 85k miles. I've got a increasing driveline vibration that's constant, this flex disk seems to be the culprit.
I'm looking for photos or information from those who have done this. What's involved, location exactly etc etc.
Thanks in advance.
I found these instructions over in Rentech from JEFF IN PA "Not overly complicated; remove the plastic underbody shields, support the transmission and remove the trans mount support bolts. Remove the trans support metal brace. At this point you should be able to see the driveshaft flex disc, remove the bolts in the disc and pull the driveshaft out while putting something under the front diff to catch any oil that may drip."
This is a source reference. Confirm exact model applicability in the original material.
