9. If the measurement exceeds 0.4 mm (0.016 in), replace the front wheel bearings. Refer to Front Wheel Bearing and Hub Replacement in Front Suspension.

Important: If the vehicle has ABS, complete this procedure in order to measure the looseness of the rear wheel bearings. If the vehicle does NOT have ABS, refer to Tire and Wheel Vibration in Vibration Diagnosis and Correction. In order to measure the runout of the rear wheel bearings, refer to Tire and Wheel Vibration in Vibration Diagnosis and Correction.

Tools Required
