Remove the wheel covers or hubcaps if applicable.
Mount the wheel onto a wheel balancer.
Follow the manufacturer’s instructions to balance the wheel.
Reinstall the wheel onto the vehicle and tighten the lug nuts to the specified torque (typically 90-130 ft-lbs).

4. Suspension Inspection

Lift the vehicle using a hydraulic jack and secure it with jack stands.
Visually inspect suspension components (tie rods, control arms, shocks) for any signs of wear or damage.
Replace any worn components, ensuring all bolts are torqued to manufacturer specifications.
