Tools Required: Tire pressure gauge, lug wrench, tire balancer (if available).
Check tire pressure and inflate to manufacturer specifications.
Inspect tires for uneven wear; replace if necessary.
If balancing is needed, remove the wheels and take them to a tire shop for balancing.

3. Suspension Component Inspection

Tools Required: Socket set, torque wrench.
Visually inspect all suspension components for signs of wear or damage.
Tighten any loose bolts or nuts to the manufacturer's torque specifications.
Replace any worn or damaged bushings or control arms as needed.

4. Driveshaft and Axle Check

Tools Required: Jack, jack stands, socket set.
Lift the vehicle using a jack and secure it with jack stands.
