Many Porsche Cayenne owners reported 'Crunch' sounds and vibrations from the rear axle, without any solution from the local dealers. They claimed all those sounds coming from the rear differential 'normal'. But such noise is certainly not normal.
We studied this problem well and concluded it comes from a worn Limited slip differential (LSD) clutch plates. As they aren't available as a spare part, we produced our own Rear LSD clutch replacement pack.
Our production technology is well-tested and approved by California Motorsports, a company specialized in rebuilding Porsche transmissions.
Instead of purchasing a super-expensive new rear differential for your Cayenne, which will eventually break down as well, you can repair yours and not just that. With this LSD repair set, you will solve this problem for good.
