Solution

1. Tire Pressure Adjustment

Use a digital tire pressure gauge to measure tire pressure.
Inflate or deflate each tire to the recommended pressure found in the owner’s manual or door jamb.

2. Wheel Alignment

Tools Required: Alignment machine, jack, jack stands, wheel chocks.
Lift the vehicle using a jack and secure it on jack stands.
Place wheel chocks behind the rear wheels for safety.
Follow the alignment machine's instructions to adjust the camber, caster, and toe settings to manufacturer specifications.

3. Suspension Inspection and Repair

Tools Required: Socket set, torque wrench, pry bar, multimeter (for electronic components).
Visually inspect shocks, struts, and bushings for any signs of wear or leaks.
Replace any damaged suspension components:
- Remove the wheel to access the suspension.
- Use a socket set to detach any affected components.
- Install new parts and torque to manufacturer specifications.

4. Steering Component Check

Inspect tie rods and steering rack for any play.
Replace any worn or damaged steering components as necessary.

5. Tire Replacement (if necessary)

If tread wear is severe, consider replacing tires.
Tools Required: Tire iron, jack, jack stands, tire machine (if changing tires).
Remove old tires and replace with new ones, ensuring proper inflation and alignment.
