Wheel Studs

Removal

NOTICE: Suspension fasteners are critical parts because they affect performance of vital components and systems and their failure may result in major service expense. New parts must be installed with the same part numbers or equivalent parts, if replacement is necessary. Do not use a replacement part of lesser quality or substitute design. Torque values must be used as specified during reassembly to make sure of correct retention of these parts.

1. Remove the wheel and tire.

2. NOTICE: Do not allow the brake caliper and anchor plate assembly to hang from the brake hose or damage to the hose may result.

Remove the 2 anchor plate bolts and position the brake caliper and anchor plate assembly aside.

- Discard the bolts.

- Support the brake caliper and anchor plate assembly using mechanic's wire.

3. Remove the brake disc.

4. Using the C-Frame and Screw Installer/ Remover, remove the wheel stud.





Installation

1. NOTE: Make sure to use washers that have an ID that is larger than the OD of the wheel stud serrations. Use enough washers (approximately 4) to allow the wheel stud to fully seat against the hub flange.

Position the new wheel stud in the wheel hub, aligning the serrations in the wheel hub flange made by the original wheel stud.

- Place approximately 4 washers over the outside end of the wheel stud and thread a standard wheel nut onto the wheel stud with the flat side against the washers.

- Tighten the wheel nut until the wheel stud head seats against the back side of the wheel hub flange.





2. Remove the wheel nut and washers.

3. Install the brake disc.

4. Position the brake caliper and anchor plate assembly and install the new bolts.
- Tighten the bolts to 250 Nm (184 lb-ft).
