Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat, stable surface, and engage the parking brake.
Wear safety gloves and goggles.

2. Inspect and Replace Brake Pads

Remove the wheel using a socket set.
Inspect the brake pads for wear; if they are below the manufacturer's minimum thickness, replace them.
Tools Required: Socket set, brake pad spreader.
Safety Warning: Ensure the vehicle is securely lifted before working under it.

3. Check and Resurface or Replace Brake Rotors

Measure rotor thickness and inspect for warping using a micrometer and runout gauge.
If warped, either resurface the rotors or replace them if they are below the minimum thickness.
Tools Required: Micrometer, runout gauge, rotor removal tool.
Safety Warning: Allow brakes to cool before handling rotors.

4. Align and Balance Wheels

Inspect the wheels for damage and check tire pressure.
Use a wheel alignment machine to ensure proper alignment.
Balance the wheels using a wheel balancer to prevent vibrations.
Tools Required: Wheel alignment machine, wheel balancer.

5. Inspect Suspension Components

Check for any loose or damaged components such as control arms, bushings, and tie rods.
Replace any worn or damaged parts as necessary.
Tools Required: Socket set, torque wrench.
Safety Warning: Always ensure the vehicle is on stable ground when inspecting suspension.
