Spotting center support bearing problems can happen from the moment you put the vehicle in gear to pull it into a bay.
Driveshaft problems can be spotted from the moment you put the vehicle in gear to pull it into a bay. As the power is transmitted from the transmission to the rear axle, the slack from worn or damaged components is taken up, resulting in a sudden crunch or pop.
Once the vehicle is moving, you might hear a whine coming from the center of the vehicle. The noise will change as speed increases and might change as power is applied. If the vehicle is put into neutral, the sound remains the same.
The problem could be the center bearing’s support. These are used if the driveline has a two-piece driveshaft. Engineers split the driveshaft into two sections to change the harmonics. The center bearing is a ball bearing mounted in a rubber cushion that attaches to a frame crossmember.
The cushion allows vertical motion at the driveline and helps isolate the vehicle from vibration. The bearing in most center supports is sealed for life. Some do have a zerk fitting from the factory, and some replacement units also have a way to lubricate the bearing.
Premature failure of the center bearing could be the result of too much driveshaft angle, the water shield being missing or damaged, road salt and moisture, or damaged rubber casings. Also, high mileage and bearing wear can contribute to premature wear. Other issues might be related to a leaking transmission or transfer case. Some of the additives in transmission fluid can rejuvenate seals in the transmission, but on the rubber of the center support bearing it can cause it to swell and degrade.
