Solution

1. Preparation

Tools Required: Jack, jack stands, lug wrench, dial indicator, torque wrench, basic hand tools.
Safety Warnings: Always engage the parking brake and wear safety glasses.

2. Remove Wheels

Loosen lug nuts on the front wheels slightly while the vehicle is on the ground.
Use a jack to lift the vehicle and secure it with jack stands.
Remove the wheels completely.

3. Inspect and Replace Brake Rotors

Inspect: Use a dial indicator to check for rotor runout. A variance of more than 0.002 inches indicates warping.
Replace (if warped):
1. Remove the caliper bolts and slide the caliper off the rotor.
2. Remove the rotor by unscrewing the retaining screws (if equipped).
3. Install new rotors, ensuring they are clean and free of oil.
4. Reinstall the caliper and torque bolts to manufacturer specifications (typically around 25-35 Nm).

4. Inspect and Replace Brake Pads

Inspect the brake pads for thickness and even wear. Replace if worn unevenly or less than 3 mm thick.
Replace:
1. Remove the caliper bracket (if applicable) to access the pads.
2. Remove old pads and install new ones, ensuring proper alignment.
3. Reassemble the caliper, ensuring it moves freely.

5. Inspect Suspension Components

Check control arms, bushings, and tie rods for play or damage.
Replace (if needed):
1. Remove the affected components as per vehicle service manual.
2. Install new parts and torque to specifications.

6. Reassemble and Test

Reinstall the wheels and torque lug nuts to specifications (typically around 100 Nm).
Lower the vehicle and perform a test drive to ensure the vibrations are resolved.
