ADJUSTMENT & PACKING
See Figures 1, 2 and 3
The rear wheel bearings are not adjustable and are lubricated by the rear axle oil. The front wheel bearings are replaced and adjusted as explained below. Note that you will need either Volvo special tools or their equivalent to perform the service.
- Remove the hub cap, and loosen the lug nuts a few turns.
- Firmly apply the parking brake and block the rear wheels. Jack up the front of the car and place jackstands beneath the jacking points. Remove the front wheels.
- Remove the front caliper as outlined in Brakes .
- Pry off the grease cap from the hub. Remove the cotter pin and castle nut. Use a hub puller to pull off the hub. On the 760 GLE remove the brake disc. If the inner bearing remains lodged on the stub axle, remove it with a puller.
- Using a drift, remove the inner and outer bearing rings.
- Thoroughly clean the hub, brake disc, and grease cap.
- Press in the new inner and outer bearing rings with a drift or bearing installation tool.
- Press grease onto both bearings with a bearing packer. If one is not available, pack the bearings with as much wheel bearing grease as possible by hand. Also coat the outside of the bearings and the outer rings pressed into the hub. Fill the recess in the hub with grease up to the smallest diameter on the outer ring for the outer bearing. Place the inner bearing in position in the hub and press its seal in with a drift. The felt ring should be thoroughly coated with light engine oil.
- Place the hub onto the stub axle. Install the outer bearing, washer, and castle nut.
- Adjust the front wheel bearings by tightening the castle nut to 45 ft. lbs. (61 Nm) to seat the bearings. Then, back off the nut 1 / 3 of a turn counterclockwise. Tighten the nut to 12 inch lbs. (1.35 Nm). If the nut slot does not align with the hole in the stub axle, tighten the nut until the cotter pin may be installed. Make sure that the wheel spins freely without any side play.
- Fill the grease cap halfway with wheel bearing grease, and install it on the hub.
- Install the front caliper.
- Install the wheels. Remove the jackstand and lower the car. Tighten the lug nuts to 60-70 ft. lbs. (81-95 Nm) and install the hub cap.
