Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Wear safety goggles and gloves.

2. Check Tire Pressure

Use a tire pressure gauge to measure the pressure of each tire.
Inflate tires to the recommended pressure found in the owner’s manual or on the driver’s side door jamb.

3. Inspect Tires

Remove wheel covers or hubcaps if installed.
Check each tire for signs of damage: bulges, cracks, or uneven tread wear.
If damaged, replace the affected tire(s).

4. Wheel Balancing

Remove the wheels from the vehicle using a socket set and torque wrench.
Mount the wheels on a wheel balancer to identify heavy spots.
Add balancing weights as needed to each wheel.
Reinstall wheels and torque to the manufacturer’s specifications.

5. Wheel Alignment

Use an alignment machine to check the alignment settings.
Adjust camber, caster, and toe angles as necessary to meet factory specifications.
Perform a test drive to confirm alignment correction.

6. Suspension Inspection

Visually inspect shocks, struts, and bushings for signs of wear or leaking fluid.
Replace any worn or damaged components with OEM or quality aftermarket parts.
