Question 1

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

Accepted Answer

The initial step for front wheel hub servicing and repair requires front wheel removal together with front disc brake caliper and front disc collection keeping detailed marks for disc-hub alignment. A dial indicator should be used to check wheel hub center looseness which must not exceed 0.05 mm (0.0020 inch). Replace the wheel hub if this limit is surpassed. The testing procedure using the dial indicator should be conducted once more to evaluate wheel hub runout before reinstalling the front components while applying torques of 109 Nm (1,114 kgf-cm, 81 ft. lbs.) on the caliper and 103 Nm (1,050 kgf-cm, 76 ft. lbs.) on the wheel. You must remove the wheel together with front wheel hub nut LH before disconnecting the front speed sensor LH and front disc brake caliper assembly LH by unfastening its two bolts as you support the caliper. First disconnect the front disc and tie rod end sub-assembly LH as well as the lower front suspension arm sub-assembly LH to remove the front wheel assembly LH using a plastic-faced hammer on the front drive shaft. Pay attention to avoid damaging either the drive shaft outboard joint boot or speed sensor rotor during the process. To proceed with front wheel replacement you should use a screwdriver to remove the front No. 1 wheel bearing dust deflector LH before using Special Service Tool: 09611-36020 to detach the lower ball joint assembly while maintaining the steering knuckle safe from damage. The front wheel hub sub-assembly LH needs to be removed by first unsticking the four bolts and removing the dust cover. The first step during installation requires securing the front wheel hub sub-assembly LH at 56 Nm (571 kgf-cm, 41 ft. lbs.) through four bolts followed by installing the lower ball joint assembly at 71 Nm (724 kgf-cm, 52 ft. lbs.). Proper grease application and clip alignment checks must be performed. Mount the new dust deflector by using Special Service Tools: 09950-70010 (09951-07150), 09608-32010, 09950-60020 (09951-00720) and a press to correctly align the holes. Two bolts along with nuts will securely attach the front wheel to the shock absorber at 153 Nm (1,560 kgf-cm, 113 ft. lbs.) while ensuring a proper drive shaft spline position. Following restoration of the front No. 1 suspension arm sub-assembly lower LH and tie rod end sub-assembly LH, the technician should install the front disc and front disc brake caliper assembly LH and torque the caliper to 81 ft. lbs. (109 Nm, 1,114 kgf-cm). A mechanic should use a 30 mm socket wrench to tighten the new hub nut to 216 Nm (2,200 kgf-cm, 159 ft. lbs.). Afterward, they should stake the hub nut with a chisel and hammer before setting the front wheel at 103 Nm (1,050 kgf-cm, 76 ft. lbs.). To complete the service replace existing parts by performing an inspection and adjustment of the front wheel alignment in addition to testing the ABS speed sensor signal.

Question 2

How to service and repair the rear Wheel hub and Wheel Bearing on Toyota Prius?

Accepted Answer

A rear wheel hub and bearing repair or servicing process begins by performing on-car checks on the hub and bearing. This procedure includes rear wheel removal and rear brake drum inspection followed by matchmarking the drum and hub bolt positions. A dial indicator should measure hub center looseness to ensure it remains below 0.05 mm (0.0020 inch); if the measurement exceeds this limit then replace the hub. A maximum wheel hub runout of 0.07 mm (0.0028 inch) requires replacement of the hub. Reposition the rear brake drum while aligning the matchmarks and place the rear wheel before torquing it to 103 Nm (1,050 kgf-cm, 76 ft. lbs.). Following the same procedural steps remove both RH and LH sides by beginning with rear wheel removal and subsequent disconnection of skid control sensor connector while avoiding any contamination of the connector. The procedure to remove the LH rear wheel hub and bearing assembly requires disassembly of 4 bolts. The axle beam receives the installed wheel hub and bearing LH component while torquing the 4 bolts to 61 Nm (622 kgf-cm 45 ft. lbs.). The next step involves reattaching the skid control sensor connector with a repeat of the looseness and runout inspections. The installation must include the rear brake drum sub-assembly and rear wheel after torquing the wheel to 103 Nm (1,050 kgf-cm, 76 ft. lbs.) and verifying the rear wheel alignment and ABS speed sensor signal.
