Solution

1. Preparation

Gather tools and parts needed for repairs.
Tools Required: Tire pressure gauge, alignment machine, jack and jack stands, torque wrench, suspension inspection tools.
Ensure the vehicle is parked on a level surface and the ignition is off.

2. Tire Pressure Adjustment

Use a tire pressure gauge to check the pressure of all tires.
Inflate or deflate tires as necessary to match the recommended pressure specified on the driver’s door jamb sticker.

3. Wheel Alignment

Position the vehicle on an alignment machine.
Adjust the alignment settings to the manufacturer’s specifications.
Tighten all adjustment bolts to the specified torque values.

4. Suspension Inspection

Lift the vehicle and securely support it with jack stands.
Visually inspect all suspension components for signs of wear or damage.
Replace any worn or damaged parts before reassembling.

5. Tire Rotation

If tire wear is uneven but not severe, consider rotating the tires to promote even wear.
Move the rear tires to the front and the front tires to the rear, crossing them if they're directional.
