Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a flat surface and secured with wheel chocks.
Disconnect the battery to avoid potential electrical issues.

2. Inspect and Replace Brake Components

Brake Pads and Rotors:
1. Remove the front wheels using a socket set.
2. Remove the caliper bolts with a socket wrench and carefully lift the caliper away from the rotor.
3. Inspect the brake pads for wear; if less than 3mm, replace them.
4. Check the rotors for grooves or warping.
5. If warped, replace the rotors; ensure they are properly torqued to the manufacturer’s specifications.
6. Reinstall the brake caliper and wheels.

3. Suspension Inspection and Repair

Suspension Components:
1. Visually inspect tie rods, control arms, and bushings for damage or excessive wear.
2. If any components are damaged, replace them as necessary.
3. Ensure all bolts are torqued to the specified values.

4. Tire Balance and Alignment

Tires:
1. Remove the tires and check for uneven wear patterns.
2. If necessary, balance the tires using a tire balancer.
3. Check alignment using an alignment machine; adjust as needed.
