- Remove the driveshafts.
- On a two-piece driveshaft, a center support bearing is used to hold the center of the shaft where the two shafts attach to each other. It bolts to the frame, cross member or underside of the vehicle. The sealed bearing is supported in a rubber mount that dampens noise and vibration.
A center bearing assembly.
- The bearing is pressed off and a new one is pressed on.
- If the two pieces of the driveshaft are separated, be sure that they are reassembled in phase. Assembling the front and rear halves out of phase can cause extreme vibration. When the shafts are not marked before disassembly, use a tape measure or a steel rod to check the alignment of the halves.
