2
Check brake pads for wear and proper installation.
3
Examine suspension components for wear, including control arms, bushings, and tie rods.
4
Test wheel bearings for play or roughness.

Solution

1. Preparation

Gather tools and parts.
Ensure the vehicle is parked on a flat surface and secure it with wheel chocks.
Disconnect the battery to ensure safety while working with brake components.

2. Raise the Vehicle

Use a jack to lift the front or rear of the vehicle as needed.
Secure the vehicle with jack stands for safety.

3. Remove Wheel Assembly

Using a lug wrench, remove the wheel by loosening the lug nuts.
Set the wheel aside in a safe location.

4. Inspect and Replace Brake Components

Brake Rotor Inspection:
- Use a dial indicator to measure rotor runout.
- If warped, replace the rotor. Torque the new rotor to manufacturer's specifications (typically 80-100 ft-lbs).
Brake Pad Inspection:
- Remove caliper by unscrewing the caliper bolts (usually 12mm or 14mm).
- Check pads for thickness; replace if less than 3mm.
- Ensure pads are correctly installed and free of debris.

5. Inspect Suspension Components

Check control arms, bushings, and tie rods for any signs of wear or damage.
Replace any worn components as necessary.
Torque all suspension bolts to manufacturer's specifications.

6. Reassemble

Reinstall the brake caliper and torque bolts to specifications.
Reattach the wheel and torque lug nuts in a crisscross pattern to ensure even tightening.
Lower the vehicle back to the ground.
