Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Safety warning: Ensure the vehicle is turned off and the keys are removed from the ignition.

2. Tire Pressure Adjustment

Use a tire pressure gauge to check each tire's pressure.
Inflate or deflate tires as needed to reach the recommended pressure found in the owner's manual.

3. Tire Inspection and Rotation

Inspect each tire for visible damage or uneven wear.
If damage is found, replace the affected tire.
Rotate tires if uneven wear is observed, following a front-to-back or crisscross pattern.

4. Wheel Balancing

Remove the wheels from the vehicle using a socket set.
Take the wheels to a professional tire shop for balancing.
Reinstall the balanced wheels, ensuring lug nuts are torqued to the manufacturer’s specifications (typically 80-100 ft-lbs for passenger vehicles).

5. Suspension Inspection and Repair

Inspect suspension components, looking for signs of wear or damage.
Replace any worn components such as bushings, shocks, or struts.
Reassemble and ensure all bolts are tightened to manufacturer specifications.

6. Wheel Alignment

Use an alignment tool to check the wheel alignment.
Adjust as necessary to bring the wheels into specification.
