Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface, engage the parking brake, and disconnect the battery if working on electrical components.

2. Inspect and Replace Brake Pads

Sub-steps:
1. Remove the wheel using a socket set.
2. Remove the brake caliper by unbolting it and lifting it off.
3. Inspect the brake pads for wear; replace if they are below 3mm thickness.
4. Install new brake pads, ensuring they are properly aligned and secure the caliper back in place.

3. Check and Resurface/Replace Rotors

Sub-steps:
1. Remove the brake rotor by unbolting it from the hub.
2. Use a run-out gauge to measure rotor warpage; if warped beyond specifications, resurface or replace the rotor.
3. Clean the rotor surface with brake cleaner before reinstalling.
4. Torque the rotor bolts to manufacturer specifications (typically around 70-90 ft-lbs).

4. Inspect and Replace Suspension Components

Sub-steps:
1. Lift the vehicle securely using jack stands.
2. Visually inspect control arms, tie rods, and other suspension components for wear.
3. Replace any damaged components using appropriate tools and torque specifications.

5. Tire Inspection and Balancing

Sub-steps:
1. Check tire pressure and condition; replace tires with uneven wear.
2. Balance tires using a tire balancing machine, if necessary.
3. Reinstall tires and torque lug nuts to specifications (typically 75-85 ft-lbs).
