Contenu
A Ford truck that has a long wheelbase comes with a pair of driveshafts that connect the transmission or transfer case to the rear axle. To support those two driveshafts, a carrier bearing is mounted between the two driveshafts, taking some of the strain off of the system. Should the carrier bearing fail, then you will need to replace it or else the driveshafts will cause excessive vibration in the vehicle and could fail entirely.
Step 1
Put the wheel chocks around the front wheels. Lift the rear of the Ford using the jack and put jack stands under the axle.
Step 2
Unbolt the rear driveshaft from the axle with the 3/8-inch ratchet and socket and an open-end wrench. Pull the driveshaft out of the axle. Unbolt the carrier bearing from the frame of the Ford with the 3/8-inch ratchet and socket. Pull the driveshafts and carrier bearing out of the transmission, then take it out from the bottom of the Ford.
Step 3
Take off the cushion, bracket and rubber isolator off of the driveshaft using your hands. Press off the bearing and dust bearing off of the driveshaft using the large press. Spray the replacement carrier bearing with the lithium grease and then press it onto the driveshaft with the press.
Reinstall the rubber insulator, cushion and bracket with your hands. Reinstall the driveshaft and carrier bearing in the drivetrain with the 3/8-inch ratchet and socket and an open-end wrench. Lower the Ford off the jack stands with the jack.
