• Q: How to replace the Front Wheel Hub Sub-Assembly LH on 2003 Toyota Highlander?

  A: Initiating Front Wheel Hub Sub-Assembly LH replacement requires front wheel removal along with the front wheel hub LH nut after unstaking its lock nut with Special Service Tool: 09930-00010 using a hammer while applying brake pressure to eliminate the lock nut. The speed sensor front LH requires its bolt removal together with wire disconnection from the shock absorber and flexible hose detachment before disconnecting the sensor bolt from the steering knuckle. The front disc brake caliper assembly LH requires its removal through the disconnection of 2 respective bolts. Disconnect the tie rod assembly LH after removing its front disc. Separate this component by taking out both the cotter pin and nut while employing Special Service Tool: 09628-62011 to complete tie rod end detachment from the steering knuckle. Remove the front suspension arm sub-assembly lower No.1 LH by taking out its bolt and two nuts before employing a plastic hammer on the front wheel assembly LH to divide the drive shaft from the wheel hub without damaging the boot and ABS speed sensor rotor and then removing the two bolts, nuts, and steering knuckle with the wheel hub. To disconnect the front LH lower ball joint assembly remove its cotter pin and nut by employing Special Service Tool: 09628-62011. A screwdriver should be used to remove the front wheel bearing dust deflector No.1 LH after which a snap ring plier helps extract the front wheel hub LH hole snap ring. To uninstall the front wheel hub sub-assembly LH use Special Service Tool: 09520-00031 to remove the wheel hub followed by Special Service Tool: 09950-00020, 09950-60010 (09951-00410), 09950-70010 (09951-07100) and a press to discard the inner race (outside). Use a T30 Torx wrench to eliminate the 4 bolts on the front LH disc brake dust cover. After removing these bolts, take out the cover from the system. For the front wheel hub LH bearing, place the inner race (outside) on the bearing and press it until it contacts Special Service Tools: 09527-17011, 09950-60010 (09951-00600) and 09950-70010 (09951-07100) while keeping the steering knuckle horizontally positioned. Use Special Service Tool: 09950-60020 (09951-00680) and 09950-70010 (09951-07100) along with a press to install the new bearing to the steering knuckle before securing the dust cover with torx wrench (T30)-tightened 4 bolts. Use Special Service Tool: 09608-32010, 09950-60020 (09951-00680) combined with 09950-70010 (09951-07100) while using a press to install the front wheel hub sub-assembly LH before installing a new snap ring with a snap ring plier. Position the front wheel bearing dust deflector No.1 LH into the appropriate ABS speed sensor holes by using Special Service Tool: 09316-60011 (09316-00011, 09316-00031) together with Special Service Tool: 09608-32010 and a hammer. Securely install the front LH lower ball joint assembly while adjusting its nut to 123 Nm (1,250 kgf-cm, 90 ft. lbs.) and then establish it with a new cotter pin. Insert and tighten the front wheel assembly LH by securing the 2 bolts and nuts and wheel assembly to the shock absorber with a torque of 210 Nm (2,143 kgf-cm, 155 ft. lbs.). Implement the bolt from the front side of the vehicle while fitting the spline part of the drive shaft assembly to the front wheel assembly. First insert ball joint and lower arm with a bolt and two nuts before tightening them to 127 Nm (1,300 kgf-cm, 94 ft. lbs.). Afterwards install the tie rod assembly LH with new hardware by nuts and cotter pins, torquing to 49 Nm (500 kgf-cm, 36 ft. lbs.). Use 2 bolts to reinstall the front disc coupled with the front disc brake caliper assembly LH before torquing them to 106.9 Nm (1,090 kgf-cm, 79 ft. lbs.). The last step involves installing the speed sensor front LH followed by the front wheel application with a torque of 103 Nm (1,050 kgf-cm, 76 ft. lbs.). Next, check front wheel alignment and monitor the ABS speed sensor signal performance.
