Solution

1. Preparation

Gather tools and materials.
Ensure the vehicle is parked on a flat surface and the parking brake is engaged.
Disconnect the battery to prevent any electrical issues.

2. Inspect and Replace Brake Pads

Remove the wheel using a socket set.
Inspect brake pads for thickness; replace if below 3mm.
Use a suitable brake cleaner to clean the caliper and rotor.
Install new brake pads, ensuring they are properly seated.

3. Check and Replace Brake Rotors

Measure rotor thickness with a micrometer; replace if below specifications.
If warping is detected, replace rotors.
Use a torque wrench to install rotors, tightening to manufacturer specifications (usually 80-100 ft-lbs).

4. Inspect and Replace Suspension Components

Use a jack to lift the car and secure it with jack stands.
Check all suspension components for play or damage. Replace any worn components such as bushings, control arms, or tie rods.
Reassemble and ensure all bolts are torqued to specifications.

5. Wheel Alignment and Balancing

Take the vehicle to a professional alignment shop.
Ensure the wheels are balanced properly to eliminate vibrations.
