Question 1

How to Replace the Rear Wheel Hub and Bearing Assembly on Toyota Sienna?

Accepted Answer

Replacement of the Rear Wheel Hub & Bearing ASSY LH (FF) requires disconnecting the rear wheel as the first step. Relieve strain on the caliper by first hanging it with string while you separate the rear disc brake caliper assy LH by unfastening its 2 bolts. fold the rear disc and the rear brake drum sub-assy and disconnect the skid control sensor wire after taking out its connector. Begin the process of hub & bearing assy LH rear wheel hub removal by unfastening its four bolts. Secure the new hub & bearing assy LH to its position with the 4 bolts while tightening them to 56 Nm (571 kgf-cm, 41 ft. lbs.). Check the bearing backlash and wheel hub deviation before reconnecting the skid control sensor wire and ensure not to twist the sensor wire during the connection procedure. After mounting the rear disc and the rear brake drum sub-assy the technician should install the rear disc brake caliper assy LH while using 2 bolts at 88 Nm (900 kgf-cm, 65 ft. lbs.) torque. The installation of the rear wheel demands a torque of 103 Nm (1,050 kgf-cm, 76 ft. lbs.) while checking the ABS speed sensor signal output for both ABS with EBD system and ABS with EBD & BA & TRAC & VSC system.

Question 2

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

Accepted Answer

Start hub front wheel hub bearing service by conducting on-car testing through dial gauge measurements at the right angles to the measurement surface which must not exceed 0.05mm (0.0020 inch) or require a bearing replacement. Check the front wheel hub bearing deviation on the surface located outside the hub bolt. The inspection process requires a dial gauge that matches the specified maximum limit. To access the front wheel hub LH you must start by disassembling the wheel followed by untightening the nut on the hub before splitting the sensor unit and finally loosening the disc brake caliper assembly bolts while providing support to the caliper system. After disassembling the components in this order Installment should be conducted using a plastic hammer to deal with the front drive shaft assembly LH separation from the front wheel hub sub-assembly LH while protecting the boot and ABS speed sensor rotor. Disassemble the system by using Special Service Tool: 09628-62011(s) to remove the lower ball joint assembly front LH and use a screwdriver to remove front wheel bearing dust deflector No.1 LH and snap ring pliers for front wheel hub LH hole snap ring. The front wheel assembly LH requires Special Service Tool: 09520-00031(s) to remove it from the vehicle along with Special Service Tool: 09950-00020, 09950-60010 (09951-00430), 09950-70010 (09951-07100)(s) and a press for separating the bearing inner race (outside). Use a torx wrench (T30) to remove the disc brake dust cover front LH followed by removing the front wheel hub LH bearing with the help of a press and Special Service Tool(s) when the steering knuckle is maintained in a horizontal orientation. Install the new front wheel hub LH bearing using Special Service Tool: 09950-60020 (09951-00810), 09950-70010 (09951-07100)(s) and a press while following the installation of the disc brake dust cover front LH to be secured with 8.3 Nm (85 kgf-cm, 74 inch lbs.) torque. All installation should happen with the front wheel hub sub-assembly LH using Special Service Tool: 09608-32010, 09950-60020 (09951-00810), 09950-70010 (09951-07100)(s) and a press while following the sequence beginning with front wheel hub LH hole snap ring installation then using snap ring pliers. Next, install the front wheel bearing dust deflector No.1 LH using Special Service Tool: 09316-60011 (09316-00011, 09316-00031), 09608-32010(s) and a hammer to Connect the front LH lower ball joint assembly by torquing the nut to 123 Nm (1,250 kgf-cm, 91 ft. lbs.) before using a new cotter pin for fastening. The front wheel assembly LH attachment requires two bolts and nuts mounting to the shock absorber assembly front LH before torquing to a standard tension of 230 Nm (2,350 kgf-cm, 170 ft. lbs.). Nuts should receive a small engine oil application on their screw sections when used again and users should minimize outboard joint boot and speed sensor rotor collisions during installation. Fasten the lower front suspension arm sub-assembly No.1 LH together with the tie rod end sub-assembly LH and front disc and front disc brake caliper assembly LH before torquing the caliper bolts to 104 Nm (1,060 kgf-cm, 77 ft. lbs.). Use a socket wrench (30mm) to install the front wheel hub LH nut and stake it with a chisel and hammer afterward while maintaining a torque of 294 Nm (3,000 kgf-cm, 217 ft. lbs.). Install the front wheel with proper torque of 103 Nm (1,050 kgf-cm, 76 ft. lbs.), then verify the front wheel alignment and test the ABS speed sensor signal.
