What to know about the Center Support Bearing:
While many of the cars on the road today use a front-wheel drive format, there are plenty of rear-wheel drive vehicles out there. These range from trucks to SUVs to passenger cars, and they all use drive shafts that connect the transmission to the rear differential in order to turn the rear wheels.
However, in very long drive shafts made with two sections, strains are difficult. A center support bearing is used to give support for the shaft, reduce strain on drivetrain parts, and enable the shaft to rotate freely. It is a universal joint that allows free motion even if the shaft isn’t fully straight. If the center support bearing is worn, seized, or damaged, you will hear excessive squeaking noises or experience a “binding” feeling when driving.
Facts to Note:
Changing the center support bearing will necessitate removing at least part of the drive shaft.
Driving with a failed or failing center support bearing can result in serious damage to the transmission, the differential, or the drive shaft.
How to Fix:
The vehicle is raised and supported on jack stands
The transmission drive shaft with the center support bearing is removed from vehicle
The defective center support bearing is removed from the driveshaft
The new center support bearing is installed to the driveshaft and driveshaft is re-installed
The vehicle is removed from jack stands and road tested for proper operation
Your center support bearing should be checked on a frequent basis (during normal maintenance, such as an oil change) for symptoms of wear and tear. It should be changed by one of your expert mechanics immediately if they notice any damage.
Common symptoms indicating you may need to change the Center Support Bearing:
Grinding/squealing noise when the vehicle is moving
A feeling of resistance/lack of performance
Importance of this service:
Because the center support bearing upholds the drive shaft and ensures that it can spin freely, part failure is a serious concern. If the bearing freezes, you can easily damage transmission parts, differential parts, or even the drive shaft itself. We recommend immediate replacement.
