Solution

1. Preparation

Tools Required: Jack, jack stands, socket set, torque wrench, OBD-II scanner
Safety Warnings: Ensure the vehicle is on a flat surface, engage the parking brake, and wear safety glasses.

2. Inspect and Replace Brake Components

Sub-steps:
1. Jack up the front of the vehicle and secure it with jack stands.
2. Remove the front wheels using a socket set.
3. Inspect brake pads for thickness (minimum thickness should be 3mm) and check rotors for scoring or warping.
4. If worn, replace brake pads and rotors with OEM parts; clean the caliper and apply brake grease to the pad backing.
5. Reinstall the wheels and torque lug nuts to the manufacturer’s specifications (usually around 80-100 ft-lbs).

3. Replace Wheel Bearings (if needed)

Sub-steps:
1. Remove the hub assembly by taking off the brake caliper and rotor.
2. Disconnect the axle nut and remove the hub to access the wheel bearing.
3. Press out the old bearing and press in a new bearing using a bearing press.
4. Reassemble the hub and brake components, ensuring all fasteners are torqued to specifications.

4. Inspect and Repair Suspension Components

Sub-steps:
1. Inspect control arms, tie rods, and bushings for damage or excessive wear.
2. Replace any worn or damaged parts with OEM components.
3. Ensure all fasteners are torqued to the manufacturer's specifications.
