Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Disconnect the battery if electrical components will be serviced.

2. Tire Pressure Adjustment

Use a tire pressure gauge to check the pressure in each tire.
Inflate or deflate the tires to meet manufacturer specifications (found on the driver’s side door jamb).

3. Inspect and Replace Tires

Remove the tires using a lug wrench.
Inspect each tire for uneven wear; replace any tires that are worn beyond acceptable limits.
Install new tires if necessary, ensuring they are balanced correctly.

4. Suspension Inspection and Repair

Inspect suspension components for wear or damage, focusing on control arms, bushings, and struts.
Replace any damaged or worn components using appropriate replacement parts.
Reassemble suspension components and ensure they are tightened to manufacturer specifications.

5. Wheel Alignment

Set up the vehicle on a wheel alignment machine.
Adjust alignment settings to manufacturer specifications for toe, camber, and caster.
Perform a test drive to confirm that the vehicle tracks straight.
