Solution

1. Preparation

Gather tools including a jack, jack stands, lug wrench, torque wrench, and a runout gauge.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.

2. Wheel Removal

Loosen the lug nuts on the affected wheel while the vehicle is still on the ground.
Use the jack to lift the vehicle and secure it with jack stands.
Completely remove the lug nuts and take off the wheel.

3. Brake Rotor Inspection

Use the runout gauge to measure the rotor’s runout.
- If the runout exceeds manufacturer specifications, replace the rotor.
Check for signs of scoring or uneven wear on the rotor surface.

4. Brake Pad Inspection

Examine brake pads for thickness; replace if they are worn below manufacturer specifications.
Ensure the brake pads are properly seated in the caliper.

5. Reassembly

If rotors and pads are in good condition, re-install the wheel.
Hand-tighten the lug nuts before lowering the vehicle.
Lower the vehicle and use a torque wrench to tighten lug nuts to manufacturer specifications.

6. Wheel Alignment and Balance (if necessary)

If the problem persists, take the vehicle to a professional for a wheel alignment and balance.
Ensure all tires are rotated as per manufacturer recommendations for even wear.
