  Q: How to replace the Front Wheel Hub LH on Toyota Matrix?

  A:

  The Front Wheel Hub LH replacement process begins by using Special Service Tool: 09930-00010 to remove the front wheel and the front wheel hub LH nut. The front wheel hub replacement requires removing the 2 bolts to disconnect the front stabilizer link assembly LH, Speed Sensor front LH (with ABS), and front disc brake caliper assembly LH from the steering knuckle. Start by removing the front disc and then utilize Special Service Tool: 09628-62011 to separate the LH sub-assembly of tie rod end and finally remove the front suspension arm sub-assembly lower No. 1 LH. The front wheel assembly LH can be removed by applying a plastic hammer to split the Drive Shaft from the wheel hub but maintain protection of the boot and speed sensor rotor from damage. Remove the 2 bolts along with 2 nuts which secure the front wheel assembly LH and continue by removing the lower Ball Joint assembly front LH through the process of extracting the cotter pin and nut and applying Special Service Tool: 09628-62011. Start by detaching the front wheel hub LH hole snap ring with snap ring pliers before extracting the front wheel hub sub-assembly LH using Special Service Tool: 09520-00031. Lastly, remove the inner race of the hub LH bearing using Special Service Tools: 09950-40011 with accompanying secondary tools (09951-04020, 09952-04010, 09953-04030, 09954-04010, 09955-04061, 09957-04010, 09958-04011), 09950-60010 and 09951-00370. Use Special Service Tool: 09527-17011, 09950-60010 (09951-00640) and 09950-70010 (09951-07100) with a press to remove the hub LH bearing from the steering knuckle by placing the inner race of hub LH bearing on the outer race. You can install a new hub LH bearing using Special Service Tool: 09950-60020 (09951-00720), 09950-70010 (09951-07100) and a press before reinstalling the dust cover front LH with 3 bolts and torqueing to 8.3 Nm (85 kgf-cm, 73 inch lbs.). Use the combination of Special Service Tools: 09608-32010, 09950-60010 (09951-00600), 09950-70010 (09951-07100) and a press to install the front wheel hub sub-assembly LH before seating the new LH hole snap ring with snap ring pliers. Reinstall the lower ball joint assembly front LH, torque the nut to 103 Nm (1,050 kgf-cm, 76 ft. lbs.), but only after installing a new cotter pin while aligning the holes through additional nut tightening when needed. Secure the 2 bolts and nuts to connect the front wheel assembly LH to the Shock Absorber with torque setting to 220 Nm (2,243 kgf-cm, 162 ft. lbs.). Insert the drive shaft assembly splined section to the front wheel assembly without forcing it through and harming the boot or rotor. The repair process requires the lower No. 1 LH front suspension arm sub-assembly and tie rod end sub-assembly LH along with front stabilizer link assembly LH installation before securing the front disc and front disc brake caliper assembly LH with 2 bolts at 106.8 Nm (1,089 kgf-cm, 79 ft. lbs.). Use the 30 mm socket wrench to install and tighten the front wheel hub LH nut to 216 Nm (2,203 kgf-cm, 159 ft. lbs.). After tightening the nut, position the chisel against the nut then strike it with a hammer. To finish the procedure replace the front wheel then torques it to 103 Nm (1,050 kgf-cm, 76 inch lbs.) before inspecting and adjusting front wheel alignment and verifying the ABS speed sensor's signal function with ABS active.

  Q: How to service and repair the front Wheel Hub on Toyota Matrix?

  A:

  The front wheel hub servicing process starts by uninstalling the front tire followed by caliper assembly separation and front disc removal. The front wheel hub bearing backlash needs dial indicator evaluation to confirm it stays under 0.05 mm (0.0020 in.); if it surpasses this threshold you should replace the bearing. The check of front wheel hub deviation against surface outside the hub bolt through dial indicator testing should lead to front wheel hub sub-assembly replacement when results exceed 0.05 mm (0.0020 in.). The front disc along with front disc brake caliper assembly and front wheel should be installed before wheel torque reaches 103 Nm (1,050 kgf/cm, 76 ft. lbs.). Detach the front wheel along with the front wheel hub LH nut before you can split the front stabilizer link assembly LH and front Speed Sensor LH and front disc brake caliper assembly LH by unfastening the 2 bolts. First remove the front disc then take off the tie rod end sub-assembly LH followed by the lower LH front suspension arm sub-assembly then proceed to separate the front wheel assembly LH using a plastic hammer with caution to avoid injuring the boot or ABS speed sensor rotor. First uninstall Special Service Tool: 09628-62011 from the lower Ball Joint assembly LH followed by using snap ring pliers to remove the LH hole snap ring. The worker should use Special Service Tool: 09520-00031 to remove the front wheel hub sub-assembly LH while using Special Service Tool: 09950-40011 (extension group: 09951-04020, 09952-04010, 09953-04030, 09954-04010, 09955-04061, 09957-04010, 09958-04011) together with Special Service Tool: 09950-60010, 09951-00370 to extract the hub LH bearing's inner race. Remove the front disc brake dust cover LH by removing its 3 bolts before you use Special Service Tools: 09527-17011, 09950-60010 (09951-00640), 09950-70010 (09951-07100) in combination with a press to detach the front wheel hub LH bearing. To install a new hub LH bearing on the Steering Knuckle users should follow the order of first using Special Service Tool: 09950-60020 (09951-00720) and 09950-70010 (09951-07100) and a press then torquing the dust cover bolts to 8.3 Nm (85 kgf/cm, 73 in. lbs). Install the hub sub-assembly LH using Special Service Tool: 09608-32010, 09950-60010 (09951-00600), 09950-70010 (09951-07100) and a press followed by installing a new LH hole snap ring with snap ring pliers. The lower ball joint assembly LH requires a new nut torqued to 103 Nm (1,050 kgf/cm, 76 ft. lbs.) while inserting a new cotter pin which should be aligned with the holes. The assembly of front wheel LH requires two bolts with nuts reaching 220 Nm (2,243 kgf/cm, 162 ft. lbs.) while avoiding Drive Shaft outboard joint boot and ABS speed sensor rotor damage. Proceed with the installation of lower LH front suspension arm sub-assembly, tie rod end sub-assembly LH, front stabilizer link assembly LH, front disc, and front disc brake caliper assembly LH while torquing caliper assembly bolts to 107 Nm (1,089 kgf/cm, 79 ft. lbs.). Place a new hub LH nut on the hub components using a socket wrench (30 mm) then torque it to 216 Nm (2,200 kgf/cm, 159 ft. lbs.). The hub LH nut requires additional staking by striking it with a chisel and hammer before installing the front wheel while torquing it to 103 Nm (1,050 kgf/cm, 76 ft. lbs.). The professional must check front wheel alignment while inspecting the ABS speed sensor signal for the Vehicle Stability Control System and Anti-lock Brake System.
