• Q: How to Service and Repair a Wheel Bearing on 2001 Toyota Prius?

  A: Service and repair of the wheel bearing starts with removing the front wheel after tightening it to 103 Nm torque (1,050 kgf-cm, 76 ft. lbs.). Start by removing the 2 bolts, brake caliper, and disc and support the brake caliper securely yet safely. Then check both bearing backlash and axle hub deviation. Check the bearing backlash at the axle hub center using a dial indicator and accept a maximum of 0.05 mm (0.0020 inch) backlash; a new bearing is required if the measurement exceeds this range. External to the hub bolt, the axle hub should measure 0.07 mm (0.0028 inch) or less at its surface or the replacement of the hub becomes necessary. The reinstall process requires utilization of 107 Nm (1,090 kgf-cm, 79 ft. lbs.) torque for the disc together with the 2 bolts and brake caliper. Apply Special Service Tool: 09930-00010 and strike the unscrew lock nut with a hammer to obtain unstaking. During wheel brake application, remove the lock nut with a torque setting of 216 Nm (2,200 kgf-cm, 159 ft. lbs.). Before operating begin by taking out the brake caliper and disc and use proper methods to support the brake caliper. Separate the ABS speed sensor by applying 8.0 Nm (82 kgf-cm, 71 inch lbs.) torque while keeping the 2 shock absorber bottom nuts with 153 Nm (1,560 kgf-cm, 113 ft. lbs.) torque but ensuring they remain in place. Disconnect the tie rod end from the steering knuckle by removing the cotter pin and nut with a torque of 49 Nm (500 kgf-cm, 36 ft. lbs.). However, if holes for a new cotter pin need realignment during replacement, increase the nut torque up to 60 degrees. The tie rod end disconnect requires Special Service Tool: 09628-62011 for completion. The two bolts and nuts which hold the lower suspension arm to the lower ball joint can be removed with a torque size of 142 Nm (1,450 kgf-cm, 105 ft. lbs.). A forensic apparatus should be used to extract the steering knuckle with its attached axle hub while maintaining the boot and ABS speed sensor rotor from damage. The procedure requires removing the 2 bolts and lower side shock absorber nuts until completion. Perform installation procedures in the opposite order of removal steps and conduct a signal test of the ABS speed sensor while verifying front wheel alignment.
