JXB B5 Driveshaft Center Support Carrier Bearing Upgrade
Audi B5 A4/S4/RS4 - Manual + Auto Transmission - B5001A0
Holds the driveshaft where it should be. Isolation dampers minimize vibrations.
The stock center support bearing carrier holds the driveshaft in place with rubber so thin about 20 lbs of force moves it from center to the end of its travel. While that’s great for making sure no NVH makes it to the cabin, the stock bushing is extremely prone to failure, especially in harsher climates and on higher-powered cars. When the bushing lets go, it leads to excessive vibrations and clunking which can damage the transmission and rear diff. To make matters worse, the stock carrier is molded onto the non-serviceable center support bearing, leading to costly driveshaft replacement.
