Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a flat surface and safely lift using a jack and jack stands if needed.

2. Tire Pressure Adjustment

Use a tire pressure gauge to check all tires.
Inflate or deflate tires to the manufacturer-recommended pressure found in the owner’s manual or on the driver’s door jamb sticker.

3. Tire Rotation/Replacement

If tires show uneven wear, rotate them to ensure even distribution or replace if necessary.
Remove each wheel using a socket set.
Inspect tread depth and sidewalls; replace tires that are worn beyond safety standards.

4. Suspension Inspection and Repair

Remove the wheel to access suspension components.
Inspect struts and shocks for leaks; replace if damaged.
Check all bushings for wear and replace any that are cracked or deteriorated.
Ensure all bolts are tightened to manufacturer specifications (refer to repair manual for torque values).

5. Wheel Alignment

After addressing any tire or suspension issues, perform a four-wheel alignment.
Use an alignment machine to adjust toe, camber, and caster angles to manufacturer settings.
