Question 1

How to service and repair the rear wheel hub on Toyota Avalon?

Accepted Answer

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.

Question 2

How to service and repair the front Wheel Hub on Toyota Avalon?

Accepted Answer

A proper front hub wheel servicing starts by detaching the front wheel before moving on to remove both the front disc brake caliper assembly LH and the front disc. A dial indicator helps evaluate front wheel hub bearing looseness at right angles to measurement surfaces, but the maximum allowable threshold is 0.05 mm (0.0020 in.); if the bearing loses excessive tightness replace it. Check the front wheel hub runout on the surface outside the hub bolt with a maximum specification of 0.05 mm (0.0020 in.) before needing to replace the wheel hub. Reinstall the front disc and front disc brake caliper assembly LH and the front wheel by torquing the wheel to 103 N m (1.050 kgf cm, 76 ft. lbf). The front disc brake caliper assembly LH on the left needs users to maintain the caliper support to prevent damaging the flexible hose during bolt removal. The technician should continue the process by removing the front disc and then separating the tie rod end sub-assembly LH as well as the front suspension arm sub-assembly No.1 LH before proceeding to remove the front wheel assembly LH and subsequently marking the front drive shaft assembly LH alongside the front wheel hub sub-assembly LH for alignment. With a plastic hammer approach the front drive shaft assembly LH from front wheel hub sub-assembly LH while keeping drive shaft boot and speed sensor rotor intact and remove all 2 bolts and nuts and steering knuckle LH and front wheel hub sub-assembly LH together. Starting with preparation for disassembly requires a screwdriver to remove front wheel bearing dust deflector No.1 LH followed by snap ring pliers to remove front wheel hub LH hole snap ring and closure of the front wheel hub sub-assembly LH with Special Service Tool: 09520-00031. A combination of Special Service Tools: 09950-00020, 09950-60010 (09951-00430), 09950-70010 (09951-07100) with a press allows removal of the bearing inner race from the front wheel hub sub-assembly LH. Later steps should utilize a torx wrench (T30) to remove the disc brake dust cover front LH and lower ball joint assembly front LH. The front wheel hub LH bearing removal process requires placing the bearing inner race onto the bearing and pressing until it contacts Special Service Tool: 09527-17011, 09950-60010 (09951-00600), 09950-70010 (09951-07100) when the steering knuckle LH is positioned horizontally. To properly assemble the parts for installation use Special Service Tool: 09950-60020 (09951-00810), 09950-70010 (09951-07100) with a press to install a new front wheel hub LH bearing after which the lower ball joint assembly front LH and the disc brake dust cover front LH should be installed and torque 4 bolts to 8.3 N m (85 kgf cm, 73 in. lbf). Use Special Service Tools: 09608-32010 and 09950-60020 (09951-00810) along with 09950-70010 (09951-07100) and a press to install the front hub sub-assembly LH followed by snapping the new front hub hole ring with snap ring pliers, completing the procedure with a front wheel bearing dust deflector No.1 LH using Special Service Tools: 09316-60011 (09316-00011, 09316-00031), 09608-32010 and a hammer to ensure the speed sensor hole matches the steering knuckle. Installer should align matchmarks while attaching the front drive shaft assembly LH to the front wheel hub sub-assembly LH followed by the steering knuckle LH joining with the front wheel hub sub-assembly LH for installation to the shock absorber assembly front LH using 2 bolts and 2 nuts tightened to 210 N m (2.140 kgf cm, 155 ft. lbf). Drivers must apply engine oil to nut and bolt threads if using the same hardware. The assembly process requires installing the front suspension arm sub-assembly lower No.1 LH alongside the tie rod end sub-assembly LH and front disc followed by the front disc brake caliper assembly LH with calibration torque of 107 N m (1.090 kgf cm, 79 ft. lbf). The installation must be carried out by unbending the brake hose. Follow the procedures for installing a new wheel hub LH nut using a socket wrench (30 mm) to achieve 294 N m (3.000 kgf cm, 217 ft. lbf) torque. Next, staple the nut following runout and looseness inspections then replace the front wheel by torquing to 103 N m (1.050 kgf cm, 76 ft. lbf), draft a new front wheel alignment design followed by checking the ABS speed sensor signal.
