LOOSENESS TEST

Except 929

1. Raise the front of the car and safely support it with jackstands.
2. Grasp the wheel at the 1 o'clock and 7 o'clock positions and shake it sideways.

3. Rotate the tire and make sure that it turns smoothly and that the bearings are not noisy.
4. If considerable play or any abnormal noise is noticed, the bearings are either worn or loose.
5. Repeat the procedure for the other front wheel.
6. Lower the vehicle.

929

1. Raise the front of the vehicle and safely support it with jackstands.
2. Grasp the wheel at the 1 o'clock and 7 o'clock positions and shake it sideways.
3. Rotate the tire and make sure that it turns smoothly and that the bearings are not noisy.

4. Remove the front wheel.
5. Remove the caliper assembly with the brake hose attached, and suspend it with wire or twine from the strut assembly. (See Section 9 for caliper removal and installation procedures.)
6. Mount a dial indicator so that the stylus is positioned on the face of the grease cap (1988 929) or on the hub collar (1989 929). Zero the indicator.
7. Grasp the rotor disc by hand and try to move it in the axial direction (in and out). Check the end-play on the dial indicator. The maximum allowable end-play is 0.002 in. (0.05mm). If the end-play exceeds that amount, replace the wheel bearing.
8. Remove the dial indicator.
9. Remove the wire or twine and install the brake caliper assembly. Torque the caliper retaining bolts to 58–86 ft. lbs. (79–116 Nm).
10. Install the wheel and torque the wheel lug nuts to 65–87 ft. lbs. (88–118 Nm).
11. Repeat the procedure for the other front wheel.
12. Lower the vehicle.
