Solution

1. Preparation

Gather tools and parts.
Ensure the vehicle is parked on a flat surface and the parking brake is engaged.
Use wheel chocks for added safety.

2. Remove Wheels

Sub-steps:
- Loosen lug nuts slightly while the vehicle is on the ground.
- Raise the vehicle using a jack and secure it with jack stands.
- Remove the lug nuts completely and take off the wheels.

3. Inspect and Replace Brake Components

Inspect Rotors:
- Check for warping using a dial indicator.
- If warped beyond specifications (usually more than 0.002 inches), replace rotors.
Inspect Brake Pads:
- Check for uneven wear; replace if worn down to the indicator.
- Ensure pads are seated properly in the caliper.

4. Check Suspension and Wheel Bearings

Suspension Inspection:
- Inspect control arms, ball joints, and tie rods for any play.
- Replace any worn or damaged components.
Wheel Bearings:
- Check for play by grasping the wheel at 12 and 6 o’clock and rocking it.
- Replace bearings if there is excessive movement.

5. Reassemble

Reinstall Wheels:
- Place the wheels back on and hand-tighten lug nuts.
- Lower the vehicle and torque lug nuts to the manufacturer’s specifications (usually around 80-100 ft-lbs).

6. Test Drive

Conduct a test drive at various speeds to confirm the issue is resolved.

Tools Required:

Jack and jack stands
Lug wrench
Torque wrench
