Solution

1. Preparation

Tools Required: Jack, jack stands, lug wrench, dial indicator, torque wrench, brake cleaner, and safety glasses.
Ensure the vehicle is parked on a flat surface and the parking brake is engaged.

2. Raise Vehicle

Loosen the lug nuts slightly while the vehicle is still on the ground.
Use a jack to raise the vehicle and secure it with jack stands.
Remove the lug nuts and take off the wheels.

3. Inspect Brake Rotors

Sub-steps:
- Use a dial indicator to measure rotor runout; a runout over 0.002 inches indicates warping.
- If warped, replace the rotors. If they're in good condition, clean them with brake cleaner.

4. Check Brake Pads

Inspect the brake pads for uneven wear. Replace if the friction material is unevenly worn or below the manufacturer's minimum thickness.
Ensure the brake pad backing is not damaged or corroded.

5. Examine Suspension Components

Check control arms, bushings, and struts for signs of wear or damage.
Replace any worn components as necessary.

6. Inspect Wheel Bearings

Check for play in the wheel bearings by hand. If there’s any movement, replace the wheel bearings.

7. Check Tire Balance and Alignment

Inspect tires for uneven wear and balance.
Take the vehicle to a tire shop for balancing and alignment if necessary.
