Solution

1. Preparation

Tools Required: Tire pressure gauge, alignment machine, jack, jack stands, wheel chocks, and torque wrench.
Ensure the vehicle is on a level surface and engage the parking brake.
Place wheel chocks behind the rear tires for added safety.

2. Adjust Tire Pressure

Use the tire pressure gauge to check the pressure of each tire.
Inflate or deflate tires to match the recommended specifications found on the driver’s side door jamb sticker.

3. Perform Wheel Alignment

Lift the vehicle using a jack and secure it with jack stands.
Remove the front wheels to access the alignment adjustment points.
Use the alignment machine to check the camber, caster, and toe settings.
Adjust the alignment settings to meet manufacturer specifications, typically using the adjustment bolts on control arms and tie rods.
Reinstall the front wheels and torque to specifications (usually around 80-100 ft-lbs).

4. Inspect and Replace Suspension Components (if needed)

Visually check the suspension components for wear or damage.
If any components (such as shocks or struts) are worn, remove the damaged parts using a socket set.
Replace with OEM or high-quality aftermarket parts, ensuring proper installation according to manufacturer specifications.

5. Final Tire Rotation

Rotate tires if uneven wear is evident to promote more even wear in the future.
Reinstall tires on the vehicle, ensuring proper torque specifications are followed.
