Seal and Bearing Replacement

Removal

1. Raise vehicle and install safety stands. Remove rear wheel and tire. Refer to Section 04-04. Remove rear brake drum (1126). Refer to Section 06-02.

2. Remove rear axle housing cover (4033) and rear axle shafts (4234).

3. NOTE: If inner wheel bearing oil seal (1177) is leaking, check the rear axle housing vent (4022). If the rear axle housing vent is plugged with dirt or debris, it will cause pressure buildup in the rear axle housing (4010) which can lead to seal leaks.

   Using Impact Slide Hammer T50T-100-A and Axle Wheel Bearing Puller T83T-1225-A, insert into the bore as shown and position behind the rear wheel bearing (1225) so the tangs on the tool engage the bearing outer race. Remove the rear wheel bearing and inner wheel bearing oil seal as a unit, using the slide hammer tool. Inspect rear wheel bearing for wear. Replace as necessary.

   

Installation

If inner wheel bearing oil seal becomes cocked in the bore during installation, remove inner wheel bearing oil seal and install a new inner wheel bearing oil seal.

   Lubricate the new rear wheel bearing with rear axle lubricant and install the rear wheel bearing into the housing bore using Axle Wheel Bearing Replacer T83T-1225-B.

   

2. Coat the lips of the inner wheel bearing oil seal with Premium Long-Life Grease XG-1-C or -K or equivalent meeting Ford specification ESA-M1C75-B and install the inner wheel bearing oil seal using Hub Seal Replacer T83T-1175-B.
