Solution

1. Preparation

Gather all necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.

2. Tire Inspection

Remove the wheel covers or hubcaps if applicable.
Inspect each tire for visible damage or irregular wear patterns.
Use a tread depth gauge to ensure adequate tread depth. Replace any tires that are worn beyond specifications.

3. Wheel Bearing Check

Lift the vehicle using a jack and secure it with jack stands.
Grasp the wheel at the 12 o'clock and 6 o'clock positions and push/pull to check for play. If there is excessive movement, the wheel bearing needs replacement.
If roughness is felt during spinning, replace the wheel bearing.

4. Suspension Component Inspection

Visually inspect struts and shocks for leaks or physical damage.
Check all bushings for signs of wear or degradation.
If any components are damaged, replace them with OEM or high-quality aftermarket parts.

5. Exhaust System Check

Inspect the exhaust system for loose hangers, cracks, or rust.
Tighten or replace any loose components as needed.

6. Reassembly and Wheel Installation

If any wheel bearings or suspension components were replaced, reassemble everything carefully.
Torque lug nuts to the manufacturer’s specifications (usually around 80-100 ft-lbs).
Reinstall wheel covers or hubcaps if removed.
