The first step for repairing or servicing the wheel bearing involves removing its individual components. Place the axle hub into a soft jaw vise which should grip the hub bolts without excessive force. The grease cap removal requires a screwdriver for 2WD while 4WD requires using a screwdriver to remove the oil seal from the inside. Starting with the axle hub removal from the steering knuckle requires the removal of its 4 bolts followed by moving the brake dust cover towards the hub. The removal of the axle hub requires Special Service Tools 09710-30021 (09710-03051) and 09950-40011 (09951-04020, 09952-04010, 09953-04020, 09954-04010, 09955-04031, 09957-04010, 09958-04011). First remove the bearing spacer along with the ABS speed sensor rotor/spacer and then peel out the outside oil seal through the use of a screwdriver. The bearing extraction from the steering knuckle requires snap ring pliers followed by Special Service Tool: 09950-60020 (09951-00810), 09950-70010 (09951-07150) along with a press. The assembly process requires insertion of a new bearing into the steering knuckle through Special Service Tool: 09527-17011, 09950-60020 (09951-00910) and a press followed by snap ring installation with snap ring pliers. Use the tools Special Service Tool: 09223-15030 and 09527-17011 with a plastic hammer to install a new oil seal onto the outside while applying MP grease to the lip of the oil seal. Replace the brake dust cover to the steering knuckle through mounting 4 bolts while torquing at 18 Nm (185 kgf.cm, 13 ft. lbs.). Then install the axle hub with Special Service Tool: 09649-17010 using a press. The installation of an ABS speed sensor rotor/spacer must be done carefully to avoid damaging the serration with Special Service Tool: 09950-60010 (09951-00650), 09950-70010 (09951-07150) and a press. Place the grease cap on 2WD vehicles while installing a new oil seal inside 4WD vehicles through the use of Special Service Tool: 09527-17011 along with a plastic hammer while applying MP grease to the oil seal lip.

The first step in repairing or servicing a wheel bearing starts with demounting the front wheel while tightening it to 110 Nm (1,150 kgf-cm, 83 ft. lbs.). A screwdriver needs to be used to take out both the shock absorber and the grease cap. 4WD models require users to disconnect the drive shaft through removal of the cotter pin alongside the lock cap before using brake force to remove the lock nut which should be torqued to 235 Nm (2,400 kgf-cm, 174 ft. lbs.). The ABS speed sensor with wire harness clamp should be removed from the steering knuckle applying 8.0 Nm (82 kgf-cm, 71 inch lbs) torque before removing the brake line bracket from the steering knuckle with 28 Nm (285 kgf-cm, 21 ft. lbs). You need to remove the front brake caliper and disc while disconnecting the lower ball joint through a process that starts with unbolting its 4 pieces followed by torque adjustment at 80 Nm (820 kgf-cm, 59 ft. lbs.). The next step requires removal of steering knuckle with axle hub after loosening the upper ball joint nut to 105 Nm (1,100 kgf-cm, 80 ft. lbs.) torque and performing steering knuckle disconnect using Special Service Tools mentioned above. Disassemble the steering knuckle by removing its nut while paying attention to the oil seal and drive shaft boot avoidance. When the drive shaft of 4WD models cannot be disconnected easily, use a plastic hammer for assistance. The installation process reverses the order of removal while ABS speed sensor signal and front wheel alignment checks should be performed.

The front wheel hub repair sequence begins with a vehicle check that requires front wheel removal followed by removing the front disc brake cylinder and front disc. After this check the wheel hub backlash with a dial indicator while verifying 0.05 mm (0.0020 inch) is not exceeded or the bearing must be replaced. Use the same tool to check the wheel hub deviation according to its specified requirements. To begin detachment start with removing the front wheel along with the grease cap through screwdriver and hammer use followed by removing the front drive shaft assembly using a cotter pin and lock cap removal process under braking conditions until the lock nut is free and then get rid of the front speed sensor by removing two bolts and finish with removing the wire harness clamp. Detach the front disc brake caliper assembly through a process of removing the bolt and brake line clamp followed by two bolts while supporting the brake caliper securely to prevent damaging the brake tube. First remove the front shock absorber assembly before disconnecting the front lower ball joint assembly through four bolts and using Special Service Tool: 09950-40011 (09951-04010, 09952-04010, 09953-04020, 09954-04010, 09955-04031, 09958-04011) to detach the steering knuckle by loosening its nut. Tapping the drive shaft lightly with a plastic hammer will make it easier to disconnect if necessary. Avoid damaging the oil seal or drive shaft boot while performing this process. Mount the wheel hub in a soft jaw vise before removing the grease cap and oil seal (used for 4WD) followed by using Special Service Tool: 09318-12010 to loosen and remove the lock nut along with the speed sensor rotor while taking caution not to damage its serration part. Unscrew four bolts and displace the dust cover to separate the wheel hub before extracting it with Special Service Tools: 09710-30021 (09710-03051), 09950-40011 (09951-04020, 09952-04010, 09953-04020, 09954-04010, 09955-04031, 09957-04010, 09958-04011). Finally discard the dust cover and bearing spacer (4WD only). Use a screwdriver to remove the outer oil seal while snap ring pliers and Special Service Tools: 09950-60020 (09951-00810), 09950-70010 (09951-07150) along with a press will take out the bearing. In reassembly the process includes using Special Service Tool: 09527-17011 and 09950-60020 (09951-00910) and a press to install a new bearing that must be followed by installing a new snap ring. Install the front wheel hub oil seal by using Special Service Tool: 09223-15030, 09527-17011 together with a plastic hammer after applying MP grease to the lip of the oil seal. You must utilize Special Service Tool: 09649-17010 with a press to install the wheel hub onto the steering knuckle which requires the dust cover to be secured by four bolts tightened to 18 Nm (185 kgf-cm, 13 ft. lbs.). The 2WD method requires the front wheel lock nut installation using Special Service Tool: 09318-12010 followed by torque application to 274 Nm (2,800 kgf-cm, 203 ft. lbs.) then staking with a chisel and hammer. The repair process for 4WD includes installing the front wheel hub grease cap along with the inner bearing spacer through the use of Special Service Tool: 09950-60010 (09951-00650), 09950-70010 (09951-07150) and a press and then fitting the oil seal (inside) with Special Service Tool: 09527-17011 and a plastic hammer while coating the lip with MP grease. Tighten the steering knuckle to upper suspension arm by nut while inserting a new cotter pin before installing the lower ball joint to the steering knuckle by using four bolts with 65 Nm (663 kgf, 48 lbft) torque. Add the front shock absorber followed by the front disc brake caliper assembly and finish by tightening the disc and brake caliper components with two bolts to 123 Nm (1,250 kgf-cm, 90 ft. lbs.) while reinforcing the brake line clamp at 28 Nm (285 kgf-cm, 21 ft. lbs.). Secure the front speed sensor along with wire harness clamp using two bolts which require torque at 8.0 Nm (82 kgf-cm, 71 ft. lbs.) followed by another clamp installation. The front wheel lock nut tightening process must be performed under brake application pressure at 235 Nm (2,400 kgf-cm, 173 ft. lbs.), followed by the installation of the lock cap and new cotter pin then the installation of the front wheel hub grease cap and front wheel using 110 Nm (1,150 kgf-cm, 83 ft. lbs.). Users must press the brake pedal several times before assessing the wheel alignment and speed sensor signals and performing sensor calibration of yaw rate and steering angle and master cylinder pressure and deceleration.

The first step of wheel bearing service and repair requires removing all components. You should remove the grease cap by placing the axle hub in a soft jaw vise and using a screwdriver on 2WD models. The procedure for 4WD demands the inward oil seal to be removed through the similar process. Special Service Tools 09710-30021 (09710-03051) and 09950-40011 (09951-04020, 09952-04010, 09953-04020, 09954-04010, 09955-04031, 09957-04010, 09958-04011) will be required for this step. The axle hub must first have its dust cover directed toward the hub side as the four bolts securing it are removed. Separate the dust cover and bearing spacer from the ABS speed sensor rotor (w/ABS) or spacer (w/o ABS). Maintain the serrations of the speed sensor rotor without scratching them. After removing the outside oil seal with a screwdriver you can extract the bearing from the steering knuckle through snap ring pliers and Special Service Tool: 09950-60020 (09951-00810), 09950-70010 (09951-07150) operated with a press.
