Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Wear safety glasses and gloves for protection.

2. Tire Pressure Adjustment

Use a tire pressure gauge to measure the pressure of each tire.
Inflate or deflate tires as necessary to reach the recommended pressure (found in the owner’s manual or door jamb).

3. Alignment Adjustment

Lift the vehicle using a hydraulic jack and secure it with jack stands.
Remove the front wheels to access the alignment adjustment points.
Adjust the camber, toe, and caster settings according to the manufacturer’s specifications using an alignment tool.
Reinstall the wheels and lower the vehicle.

4. Suspension Inspection and Repair

Inspect all suspension components for wear or damage.
Replace any worn components (shocks, struts, or control arms).
Tighten bolts to manufacturer torque specifications using a torque wrench.

5. Tire Replacement (if necessary)

If tire wear is excessive, replace the affected tires.
Ensure new tires are balanced properly before installation.
