The first step to perform wheel bearing maintenance starts with separating its components. Begin 2WD bearing service by removing the grease cap when you mount the axle hub in a soft jaw vise and use a screwdriver. The 4WD requires removal of its internal oil seal that follows the same procedure. To start the 2WD procedure first apply Special Service Tool: 09318-12010 to remove the lock nut while gently striking the staked portion with a chisel and hammer before carefully extracting the speed sensor rotor without harming its serration pattern. The process to remove the axle hub from the steering knuckle requires removing its 4 bolts and dust cover then employing Special Service Tool: 09710-30021 (09710-03051), 09950-40011 (09951-04020, 09952-04010, 09953-04020, 09954-04010, 09955-04031, 09957-04010, 09958-04011) to detach the hub completely. The first step is to remove both the dust cover and the 4WD-specific bearing spacer together with speed sensor rotor. Take out the oil seal (outside) with a screwdriver before pulling out the bearing from the steering knuckle by using snap ring pliers and Special Service Tool: 09950-60020 (09951-00810), 09950-70010 (09951-07150) with a press. When reinstalling the bearing use Special Service Tool: 09527-17011 and a press followed by installing a new snap ring by using snap ring pliers. The new oil seal (outside) installation procedure requires Special Service Tools: 09223-15030 along with 09527-17011 and a plastic hammer to apply MP grease on the seal's lip. 4 bolts secure the dust cover onto the steering knuckle at 18 Nm torque (185 kgf-cm, 13 ft. lbs.). The installation of the axle hub requires Special Service Tool: 09649-17010 with a press. The procedure for 2WD requires new lock nuts installed with Special Service Tool: 09318-12010 then torqued to 274 Nm (2,800 kgf-cm, 203 ft. lbs.) followed by chiseling and hammering the stake. Before moving to installing the oil seal (inside), experts must use Special Service Tool: 09527-17011 with a plastic hammer and apply MP grease to the seal's lip.

Connect the steering knuckle and install the nut with a new cotter pin, tightening the nut further up to 60° if the cotter pin holes are misaligned, with a torque of 105 Nm.

Install a new bearing using Special Service Tool: 09527-17011, 09950-60020 (09951-00910) and a press.
