Special Tool(s)





Removal and Installation
1. Remove the wheel cap.

2. CAUTION: Do not use heat to loosen a seized wheel nut or damage to the wheel and wheel bearing can occur.

With the weight of the vehicle on the wheels, loosen the wheel nuts.
3. With the vehicle in NEUTRAL, position it on a hoist.
4. Remove the wheel and tire assembly.
5. Remove the brake caliper anchor plate bolts.
- To install, tighten to 210 Nm (155 ft. lbs.).

6. CAUTION: Do not allow the brake caliper to hang from the hose or damage to the hose may result.

Position the caliper, pads and anchor plate aside.
7. Remove the brake disc.





8. Using the special tool, remove the wheel stud.
9. To install, reverse the removal procedure.





10. CAUTION: Do not use power tools to install the wheel stud. The serrations on the stud can be stripped.

NOTE: Do not use the wheel nut that came with the vehicle.

Install washers and a new wheel nut on the wheel stud and tighten the nut until the stud seats against the flange.
- Discard the wheel nut and washers.

11. WARNING: When installing a wheel and tire, make sure to remove any corrosion, dirt or foreign material present on the mounting surfaces of the wheel and brake disc. Installing a wheel without correct metal-to-metal contact at the mounting surfaces can cause the wheel nuts to loosen and the wheel to come off while the vehicle is in motion, causing loss of control.

Clean the wheel mounting surfaces.





12. WARNING: Retighten at 800 km (500 miles) after any wheel change or any time the wheel nuts are loosened. Failure to retighten the wheel nuts at the mileage specified could allow the wheels to come off while the vehicle is in motion, possibly causing loss of control.

CAUTION: Failure to tighten the wheel nuts in a star pattern can result in high brake disc runout, which will speed up the development of brake roughness, shudder and vibration.

Tighten the wheel nuts to 135 Nm (100 ft. lbs.) in the sequence shown.
