Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a flat surface and turn off the ignition.
Wear safety gloves and goggles.

2. Tire Pressure Adjustment

Use a tire pressure gauge to check each tire.
Inflate tires to the recommended pressure found in the owner’s manual or on the driver’s side door jamb.
Replace valve caps after adjustments.

3. Wheel Alignment

Lift the vehicle using a floor jack and secure it on jack stands.
Remove the front and rear wheels.
Attach the alignment machine sensors to the vehicle.
Adjust the toe, camber, and caster according to manufacturer specifications.
Reinstall the wheels and lower the vehicle.

4. Suspension Inspection

Visually inspect all suspension components for signs of wear or damage.
Replace any worn parts such as struts, shocks, or bushings.
Tighten all suspension bolts to the manufacturer’s torque specifications.

5. Tire Rotation

Remove the tires from the vehicle.
Rotate tires according to the recommended pattern (e.g., front to back, cross-pattern).
Reinstall tires and ensure lug nuts are torqued to the specified value.

6. Brake Inspection

Check brake calipers for sticking or signs of wear.
Replace calipers if necessary and ensure they are properly aligned.
Inspect brake pads for uneven wear and replace if needed.
