The longer wheelbase models of the 1989 Chevrolet S-10 use a two-piece driveshaft to turn the rear wheels. These two pieces of the driveshaft are connected with a center bearing known as the carrier bearing. If this starts to squeak or break down, eventually it can fail and cause problems with the driveshaft as a whole. To fix the problem, the driveshaft has to be removed from the vehicle and the carrier bearing taken off. This process should take about an hour to do.
Tools Used: Jack, Jack stands, Drain pan, Open-end wrench set, 24-inch pry bar, 3/8-inch ratchet and socket set
Remove Drive Shaft Bearing
Lift up the truck using the jack and put it on four jack stands so you have enough room to work underneath the vehicle. Place a drain pan underneath the connection between the driveshaft and the transmission.
Unbolt the straps securing the driveshaft to the axle using an open-end wrench. Use the 24-inch pry bar to pop the u-joint on the driveshaft out of the axle and then slide the rear driveshaft out of the carrier bearing and away from the vehicle.
Unbolt the strap on the center carrier bearing using the 3/8-inch ratchet and socket. Pull out the support bracket and driveshaft assembly from the rear of the transmission by hand and bring the assembly to the press. Press the carrier bearing off of the carrier bearing using the press.
