Solution

1. Preparation

Gather all necessary tools and parts. Ensure the vehicle is parked on a level surface.
Tools Required: Jack and jack stands, lug wrench, dial indicator, torque wrench, brake cleaner, and appropriate socket set.

2. Lift the Vehicle

Use the lug wrench to loosen the lug nuts on the front wheels, but do not remove them yet.
Raise the front of the vehicle using a jack and secure it with jack stands.
Remove the lug nuts and take off the front wheels.

3. Inspect Brake Components

Brake Rotors:
- Use a dial indicator to measure rotor runout. If warping exceeds 0.002 inches, resurface or replace the rotors.
Brake Pads:
- Remove caliper bolts using the appropriate socket. Lift the caliper off the rotor and inspect the pads for uneven wear. Replace if necessary.

4. Check Wheel Bearings and Suspension

With the wheel off, grasp the hub and check for play in the wheel bearings. If movement is detected, replace the bearings.
Inspect the suspension components for any visible signs of wear or damage. Replace any worn bushings or control arms.

5. Reassemble and Lower the Vehicle

Reinstall the brake caliper and tighten the caliper bolts to the manufacturer’s torque specification.
Reattach the wheel and hand-tighten the lug nuts.
Lower the vehicle back to the ground and torque the lug nuts to the specified value.
