  • One and done solution to the OEM center support bearing failure issue that plagues 1st gen Cayennes/Touaregs.

  • Installs without having to remove or disassemble the driveshaft


The 1st gen Cayenne/Touareg has a nearly 100% rate of center support bearing failure from the factory. We’ve done extensive research into the root cause of the failures, and found the issue lies in a 5° misalignment between the transfer case and the front half of the driveshaft. In order to align the driveshaft correctly, the center support bearing would have to be up through the ceiling of the center tunnel. Since the attachment of the driveshaft to the transfer case is a rubber guibo, which cannot articulate without imparting forces into the driveshaft, it is unable to deal with this misalignment without causing the driveshaft to vibrate. This vibration quickly wears out the OEM center support rubber.

Our solution is a center support bearing carrier that is strong enough to resist constant driveshaft vibration, yet soft enough to absorb it without transmitting it to the cabin. Finding the balance between performance and vibration absorption is very tricky, but after many iterations of bushing and frame design, we believe we’ve found the best possible solution.

The 2-piece design clamps around the original bearing, so does not require disassembly of the driveshaft or special tools. We offer an optional tunnel brace that makes installation easier. See the install video for details.

One interesting takeaway from our research was these driveshafts spin smoother as their guibos age. While experimenting, we replaced a guibo on an older vehicle. Driving the car up on a lift, it became apparent there was much more driveshaft vibration with the new guibo than the old. As guibos age they become softer, increasing their ability to soak up the angular misalignment without imparting radial forces on the driveshaft. So, if you’re thinking about replacing your guibo “while you’re in there”, don’t. We only recommend replacing them if they’re truly failing. A few small cracks are normal. Keep in mind they’re not solid rubber, so a crack doesn’t mean it’s about to catastrophically fail. They have a wound fibrous core like a tire that holds them together. The rubber is just the glue that holds the fibers in place.
