Solution

1. Preparation

Gather tools and parts: wheel chocks, jack, jack stands, torque wrench, tire pressure gauge, balancing weights, alignment equipment.
Ensure vehicle is parked on a flat surface and turn off the ignition.

2. Tire Pressure Adjustment

Using a tire pressure gauge, check the pressure of all four tires.
Inflate or deflate tires to match the recommended pressure found in the driver’s door jamb.

3. Tire Inspection and Replacement

Inspect each tire for visible damage or bulges.
If tires are worn unevenly, replace them with new tires of the same specifications.
Ensure that the new tires are mounted correctly, following the vehicle's rotation pattern.

4. Wheel Balancing

Remove the wheels using a socket set and place them on a balancing machine.
Add or adjust balancing weights as needed to achieve proper balance.
Reinstall the wheels and torque to manufacturer specifications (typically around 80-100 ft-lbs).

5. Wheel Alignment

If misalignment is detected during inspection, proceed to adjust the alignment.
Adjust the camber, caster, and toe angles to meet manufacturer specifications using alignment equipment.
Test drive the vehicle to ensure proper alignment has been achieved.
