Precision Parts HB88508 Drive Shaft Center Support Bearing

The Precision Parts HB88508 is a drive shaft center support bearing (also called a carrier bearing) designed to stabilize the driveshaft assembly on trucks, vans, and SUVs. By supporting the mid-section of a two-piece driveshaft, this bearing maintains proper driveline alignment, reduces vibration, and helps prevent premature wear of surrounding drivetrain components.
