2001 Toyota Corolla Wheel Bearing Parts Q&A

• Q: How to service and repair the wheel bearing on 2001 Toyota Corolla?

  A: Before initiating maintenance on the wheel bearing start by taking off the front wheel assembly. Inspection of bearing backlash and axle hub deviation starts by first removing the 2 bolts along with brake caliper and disc and afterward placing the brake caliper in a stable holder. The axial distance measurement at the axle center should be checked with a dial indicator. The reading must stay below 0.05 mm (0.0020 inch). If the measurement exceeds this threshold then the bearing needs replacement. Check the axle hub surface deviation located outside the hub bolt position because any measurement greater than 0.07 mm (0.0028 inch) requires a new hub. Insert the disc together with brake caliper and 2 bolts while torquing them to 88 Nm (900 kgf-cm, 65 ft. lbs.). You must first remove the cotter pin together with lock cap from the drive shaft lock nut before you can uninstall this nut while gently braking the system. Disconnect the two bolts along with the brake caliper and disc while maintaining secure support to the brake caliper. The ABS speed sensor needs removal of its bolt to disconnect in vehicles that possess this feature. Tearing down the flexible hose requires you to remove its bolt. The procedure to separate the tie rod end from the steering knuckle includes removing the cotter pin as well as the nut then employing Special Service Tool: 09628-62011. You must disconnect the lower suspension arm from the lower ball joint through dispatching the bolt and removing both nuts. The removal of steering knuckle with axle hub requires removing all 2 bolts and nuts while paying attention to protect both boot and ABS speed sensor rotor. The installation process begins with installing the steering knuckle and axle hub assembly to the shock absorber but take care to avoid damaging the boot and ABS speed sensor rotor before applying engine oil to the 2 nuts threads. You must fasten and torque the 2 shock absorber lower bolts and nuts to reach 2,800 kgf-cm (203 ft. lbs, 274 Nm). Attach the lower suspension arm to its lower ball joint before torquing the joints to 142 Nm (1,450 kgf-cm, 105 ft. lbs.). Affix the tie rod end to the steering knuckle and apply the new cotter pin when installing the nut. The nut requires further tightening by 60 degrees when the holes are misaligned and torque it to 49 Nm (500 kgf-cm, 36 ft. lbs.). Install the flexible hose while applying 29 Nm torque (300 kgf-cm or 22 ft. lbs.) to this connection and connect the ABS speed sensor if needed with 8.0 Nm torque (82 kgf-cm or 71 inch lbs.). The drive shaft lock nut installation process requires users to reinstall the disc, brake caliper, and 2 bolts at 88 Nm (900 kgf-cm, 65 ft-lbs) torque, then they must apply the brakes to torque the nut to 225 Nm (2,300 kgf-cm, 166 ft-lbs), followed by installing the lock cap and new cotter pin with additional nut tightening up to 60 degrees if needed. After checking bearing backlash and axle hub deviation measurement you can mount the front wheel while torquing to 76 ft. lbs. (1,050 kgf-cm, 103 Nm). Check the brake pedal several times and inspect the front wheel alignment before verifying the ABS speed sensor signal.
