• Q: How to service and repair the rear wheel hub on 2003 Toyota Avalon?

  A: The procedure to service and repair the rear wheel hub starts with removing the rear wheel and tightening it to 103 Nm (1,050 kgf-cm, 76 ft. lbs.). Securely support the brake caliper after it has been removed with its disc while applying 47 Nm (475 kgf-cm, 34 ft. lbs.) torque. A dial indicator should measure bearing backlash at the center of the axle hub which must not exceed 0.05 mm (0.0020 inch) or the hub needs replacement. A replacement of the axle hub will be required if the deviation measurement at the axle hub surface surpasses 0.07 mm (0.0028 inch) outside the hub bolt. To remove the ABS speed sensor disconnect it with a 8.0 Nm (82 kgf-cm, 71 inch lbs.) torque bolt. You must remove the rear axle hub through a four bolt procedure with 80 Nm torque (820 kgf-cm, 59 ft. lbs.) while eliminating the O-ring before applying new MP grease to the O-ring during installation. You should tighten nut A to 196 Nm (2,000 kgf-cm, 145 ft. lbs.) if reusing it along with 255 Nm (2,600 kgf-cm, 188 ft. lbs.) for new nut A followed by 181 Nm (1,850 kgf-cm, 134 ft. lbs.) for nut B. When the suspension reaches stability, perform nut torques and apply engine oil to the threads of A nuts if you plan to reuse them. Unfasten the strut rod from the rear axle carrier through bolt and nut removal while keeping the nut stationary, apply 113 Nm (1,150 kgf-cm, 83 ft. lbs.) torque to the bolt. The shock absorber installation process begins by removing nuts and bolts on its lower side followed by disconnection of No. 1 and No. 2 lower suspension arms from the axle carrier through nut and washer and bolt removal. Conclusion of the procedure involves taking out the rear axle carrier. When installing the system start by following all removal steps in the opposite order while performing ABS speed sensor signal and rear wheel alignment checks.
