Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Disconnect the 12V battery to prevent any electrical issues while working.

2. Inspect and Replace Brake Components

2.1 Check Brake Pads

Remove the wheel using a socket set.
Inspect the brake pads for wear; replace if they are below the minimum thickness (usually below 3mm).
Tools Required: Socket set, brake pad gauge.

2.2 Check Brake Rotors

Use a dial indicator to measure rotor runout; maximum acceptable runout is generally 0.002 inches.
If warping is detected, either resurface the rotors or replace them.
Tools Required: Dial indicator, torque wrench.

3. Suspension and Steering Inspection

Inspect control arms, tie rods, and other suspension components for any signs of wear or damage.
Replace any worn or damaged components with OEM parts.
Tools Required: Socket set, pry bar.

4. Wheel Alignment

After replacing any worn brake or suspension components, perform a four-wheel alignment.
Adjust camber, caster, and toe settings to manufacturer specifications.
Tools Required: Alignment machine.

5. Reassemble and Test

Reinstall the wheel and torque the lug nuts to manufacturer specifications (typically 100-120 ft-lbs).
Reconnect the battery and perform a test drive to ensure the issue is resolved.
Tools Required: Torque wrench.
