The rear wheel bearings are not adjustable.
Wheel bearings that need replacing may be indicated by a noise that occurs only during turning. Diagnose the wheel bearings as follows:
Road test the vehicle on a smooth road. Make sharp turns to the right and left.
- If the vehicle makes noises on right turns, the left wheel bearing may need to be replaced.
- If the vehicle makes noises on left turns, the right wheel bearing may need to be replaced.
- Raise and safely support the vehicle.
- Using one hand on top of the tire and one hand on the bottom, rock the wheel assembly to check for wheel bearing looseness.
- Spin the tire quickly by hand and be sure that the tire rotates smoothly and without noise from the wheel bearings.
- Remove the wheel and disc brake caliper.
- Position a dial indicator, such as Ford Position Dial Indicator with Bracketry TOOL-4201-C, against the wheel bearing hub. Push and pull on the hub and read the hub movement range on the dial indicator. The maximum allowable hub play is 0.002 in. (0.05mm). If end-play exceeds the specified value, replace the wheel hubs.
