Solution

1. Preparation

Gather tools and parts required.
Ensure the vehicle is on a flat surface and engage the parking brake.
Use wheel chocks to prevent movement.

2. Remove Wheels

Tools Required: Socket set, jack, jack stands
Sub-steps:
1. Loosen wheel lug nuts slightly while the vehicle is on the ground.
2. Raise the vehicle using a jack and support it with jack stands.
3. Remove the wheels completely for access to the brake components.

3. Inspect and Replace Brake Components

Tools Required: Torque wrench, brake cleaner, C-clamp or brake tool
Sub-steps:
1. Remove the brake caliper by loosening the caliper bolts and sliding it off the rotor.
2. Check brake pads for wear; replace if they are below 3mm thick.
3. Inspect rotors for warping; if warped, replace with new rotors.
  - If rotors are within specifications, consider having them resurfaced.
4. Clean the rotor surface with brake cleaner before reassembly.
5. Reinstall the caliper and torque bolts to manufacturer specifications.

4. Address Suspension Issues

Tools Required: Wrench set, pry bar
Sub-steps:
1. Inspect control arms and bushings for cracks or excessive play.
2. Replace any damaged suspension components as necessary.
3. Recheck wheel alignment; adjust if necessary after any suspension repairs.

5. Reinstall Wheels and Lower Vehicle

Tools Required: Torque wrench
Sub-steps:
1. Reinstall the wheels and hand-tighten lug nuts.
2. Lower the vehicle off the jack stands.
3. Tighten lug nuts to the manufacturer's specified torque.
