Wheel Hub: Testing and Inspection
DESCRIPTIONWheel bearings that need replacing may be indicated by a noise that occurs only when turning.
PROCEDURES
1. 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 the left turns, the right wheel bearing may need to be replaced.
2. Raise the front of the vehicle and check for loose wheel bearings by rocking the tires at top and bottom.
3. Spin the tire quickly by hand and make sure the tire turns smoothly without noise from the wheel bearings.
NOTE: Be careful not to confuse lower ball joint looseness with wheel bearing looseness.
4. Remove the wheel and disc brake caliper.
5. Position Dial Indicator with Bracketry TOOL-4201-C or equivalent against the wheel hub, then push and pull the wheel hub. Measure the end play of the wheel hub and wheel bearing assembly. The maximum allowable end play is 0.05mm (0.002 inch). If the end play exceeds the specified limit, replace the wheel hubs.
