Solution

1. Preparation

Gather tools including a jack, jack stands, tire pressure gauge, and alignment tools.
Ensure the vehicle is parked on a level surface and the engine is off.

2. Tire Pressure Check

Use a tire pressure gauge to measure the pressure in each tire.
Inflate or deflate tires as necessary to match the recommended pressure listed on the vehicle’s door jamb sticker.

3. Inspect and Replace Tires (if necessary)

Check for any signs of uneven wear; if the tread is significantly worn on one side, consider rotating or replacing the tires.
If replacement is needed, choose tires that match the specifications for the vehicle.

4. Wheel Alignment

Using an alignment machine, adjust the toe, camber, and caster angles to manufacturer specifications.
Torque the adjustment bolts to the specified values (typically around 50-70 ft-lbs depending on the component).

5. Suspension Inspection and Repair

If damaged suspension components are found during the visual inspection, replace them as necessary.
Common components include control arms, strut assemblies, and bushings.
Ensure all nuts and bolts are torqued to the manufacturer's specifications.
