  Q: How to Service and Repair a Wheel Bearing on Toyota MR2 Spyder?

  A:

  You can start servicing wheel bearings after removing the rear wheel then torque to 103 Nm (1,050 kgf-cm, 76 ft. lbs.). Inspect the bearing backlash and measure axle hub deviation by supporting the Brake Caliper during this process until you reach the dial indicator's maximum allowable limit of 0.05 mm (0.0020 inch) near the center point of the axle hub. Excessive values require new bearing replacement. The surface of the axle hub needs to be checked outside the hub bolt for deviation that should not exceed 0.07 mm (0.0028 inch). If the measurement is beyond the limit, replace the axle hub. Install the disc and brake caliper through the fixing of their two bolts until they reach a torque of 59 Nm (602 kgf-cm, 44 ft. lbs.). Feed the drive shaft lock nut through Special Service Tool: 09930-00010 and hit it with a hammer to unstake the nut before removing it under braking conditions and torquing it to 216 Nm (2,200 kgf-cm, 159 ft. lbs.). Replacement of the lock nut is required for installation. First detach the brake caliper while removing its 2 bolts and securing it before removing the ABS speed sensor with bolt and sensor by using 8.0 Nm (82 kgf-cm, 71 inch lbs.) torque for the bolt and then 5.0 Nm (51 kgf-cm, 44 inch lbs.) torque for the wire harness clamp bolt on the axle carrier. The Shock Absorber's lower side nuts should be slightly loosened to 173 Nm (1,765 kgf-cm, 128 ft. lbs.) without removing either of the nuts or bolts. Disconnect the strut rod through removal of the bolt and nut from the rear axle carrier that requires 78 Nm (796 kgf-cm, 58 ft. lbs.) torque. Avoid turning the nut during removal and restore suspension stability before installing the bolt. Depart the No. 1 lower suspension arm into service by taking off the bolt and nut from the rear axle carrier where torques reach 103 Nm (1,051 kgf-cm, 76 ft. lbs.). Maintain safe suspension positioning when torquing both bolt and nut. Disconnection of the No. 2 lower suspension arm requires a removal of its torqued nut at 49 Nm (500 kgf-cm, 36 ft. lbs.) followed by using new nut installation and achieving torques post-suspension stabilization through the tool 09610-20012. The drive shaft must be disconnected at the axle hub while using a plastic hammer to protect both the boot and ABS speed sensor rotor. The procedure to remove the axle carrier with axle hub includes 2 bolts and 2 nuts and 4 washers located at the shock absorber's lower side followed by applying engine oil to the nut threads prior to installation before performing the carrier hub removal in a cautious manner to protect the boot and ABS speed sensor rotor. The procedure of installation reverses the removal sequence and a post-installation check should verify that the ABS speed sensor signals function properly while inspecting rear wheel alignment.
