RacingDiffs rear differential repair kit for Porsche Porsche Cayenne 958

Many Porsche Cayenne owners reported 'Crunch' sounds and vibration from the rear axle, with no solution from the local dealers who claimed all these sounds are 'normal'. However, such noise is certainly not normal.

RacingDiffs engineers studied this problem well and concluded it comes from worn Limited Slip Differential (LSD) clutch plates. As they are not available as a spare part, RacingDiffs produced their own rear LSD clutch replacement pack.

RacingDiffs production technology is well-tested and approved by California Motorsports, a company specialized in rebuilding Porsche transmissions.
Instead of purchasing an expensive new rear differential for your Cayenne which will eventually break down with the same issue as well, you can instead repair your differential and permanently solve this problem.
