- Raise the vehicle with a jack. Support the frame with chassis stands.
- Remove the brake caliper from the bracket. Secure the caliper with a wire so that it does not interfere with the work process. Refer to FRONT DISC BRAKE CALIPER .
- Remove the disc rotor. Apply penetrating oil to the bearing and disc rotor contact surfaces if the surfaces are stuck together because of rust.
- Inspect the hub unit bearing. Refer to INSPECTION below.
- Use a dial gauge to measure the bearing axial rattle.
Bearing axial rattle: 0.05 mm Max
If abnormal conditions are discovered during inspection, go to Step 6. If there are no abnormal conditions, reassemble the front disc rotor and caliper.
NOTE: Hub, wheel bearing and spindle is integrated to the hub unit bearing so it must not be disassembled. If it has abnormal rattle or noise, replace the hub unit bearing. - Remove the ABS sensor connector.
- Remove the 4 bolts fixing the hub unit bearing to the knuckle. Apply penetrating oil to the bearing and knuckle contact surfaces if the surfaces are stuck together because of rust.
- Temporarily install long bolts to 2 of the fixing bolt holes (the bolts must have the same diameter and thread width).
- Strike the long bolts with a hammer to loosen and remove the hub unit bearing from the knuckle. Take care not to drop the bearing.
- If necessary, replace the wheel pin in the following manner.
- Place hub on a suitable work surface and remove wheel studs, as required, using a hammer.
