Connecting the two sections of the driveshaft is a center support bearing, which is a "U" shaped metal bracket with a solid-rubber machined bearing on the inside. The bearing is designed to keep both parts of the driveshaft solid in order to reduce harmonic vibration as the vehicle accelerates.
Center support bearings are used when the driveshaft is split into two sections. It serves as a junction on the drive shaft between the transmission and the differential allowing the driveshaft to flex, relieving stress on other drive line components.
When you need to replace a drive shaft center support bearing, U-joint, or driveshaft U-bolts, O'Reilly Auto Parts carries a selection of replacement driveshaft and drivetrain parts for a complete repair.

Importance of a functioning center support bearing in a vehicle, signs of failure, and choosing quality replacement for optimal performance.
This best-in-class center bearing addresses noise, vibration and harshness (NVH) levels to deliver a smoother, quieter operation for downspeed drivetrains. A user-friendly installation further reduces the possibility of future alignment-based issues.
A center support bearing is used to provide support for the shaft, reduce strain on drivetrain components, and allow the shaft to turn freely. It is a universal joint that allows free motion even if the shaft isn’t fully straight.
