Solution

1. Preparation

Gather tools and parts.
Ensure the vehicle is parked on a flat, level surface and turn off the engine.
Tools Required: Jack, jack stands, tire pressure gauge, alignment machine, socket set.

2. Adjust Tire Pressure

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

3. Wheel Alignment

Lift the vehicle using a jack and support it with jack stands.
Remove any wheel covers if applicable.
Attach the alignment machine to the front wheels and perform the alignment according to the manufacturer’s specifications.
Adjust the camber, caster, and toe settings as necessary.

4. Inspect and Replace Suspension Components

Visually inspect struts, shocks, and bushings for signs of leakage or wear.
If any components are damaged, replace them with OEM parts.
Tools Required: Socket set, torque wrench, pry bar.

5. Tire Rotation

Rotate the tires according to the manufacturer's recommended pattern to promote even wear.
If any tires are excessively worn beyond safe limits, replace them with new tires.
