The Problem: 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, it doesn’t keep the bearing centered well under load, allows the bearing to sag over time and ruin the driveshaft alignment, and creates slop in the driveline during shifts and throttle application. Over time the OEM bushing sags and becomes brittle, eventually dry rotting and cracking. Even on the best-kept cars, the stock bushing can start to from cracks in as little as 5-10 years. When the bushing lets go, it can lead to excessive vibration and clunking, and put more stress on the bearing. To make matters worse, the stock carrier is molded onto the center support bearing, so it’s not easy to replace without special tools.
