2003 Toyota Avalon Wheel Hub Parts Q&A

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

  A: The process for wheel hub maintenance begins with taking off the front wheel while tightening its bolts to 103 Nm (1,050 kgf-cm, 76 ft. lbs.). First measure the bearing backlash and axle hub deviation by detaching the 2 bolts, brake caliper and disc while maintaining a tight grip on the brake caliper. A dial indicator should measure backlash at the center point of the axle hub near the center with an allowable limit of 0.05 mm (0.0020 inch). If the measurement exceeds this threshold, replace the bearing. It is crucial to check the deviation at the axle hub surface beyond the hub bolt using a maximum 0.05 mm (0.0020 inch) limit; if the limit is exceeded the axle hub needs replacement. Securely reattach the disc with brake caliper along with reinstalling two bolts while applying 107 Nm (1,090 kgf-cm, 79 ft. lbs.) torque strength. The drive shaft lock nut needs removal through the steps of first dislodging the cotter pin along with the lock cap followed by brake application to loosen the nut with 294 Nm (3,000 kgf-cm, 217 ft. lbs.) torque. Take out disc and brake caliper a second time followed by securely supporting the brake caliper while removing its 2 bolts. Begin the ABS speed sensor wire disconnection process by unscrewing the bolt with torques set at 8.0 Nm (82 kgf-cm, 71 inch lbs.). Before securing it in place during assembly, apply engine oil to the threads of the nuts at the bottom shock absorber side while using 211 Nm of torque (2,150 kgf-cm, 156 ft. lbs.). Possible through the use of SS Tool 09610-20012 and by removing its nut which requires a 49 Nm torque force (500 kgf-cm, 36 ft. lbs.) while also removing the cotter pin. The lower ball joint requires removal from the lower suspension arm when disconnected following torque procedures at 127 Nm (1,300 kgf-cm, 94 ft. lbs.) for all 2 nuts and the bolt. The process for steering knuckle and axle hub removal involves two nut and bolt fasteners located below the shock absorber that should be unscrewed while safeguarding the boot and ABS speed sensor rotor. Installation proceeds through the reverse sequence of removal before checking both ABS speed sensor signals and measuring front wheel alignment. The installation of VSC requires performing a steering angle sensor zero point calibration procedure following system installation.
