Solution

1. Preparation

Gather tools and parts.
Ensure the vehicle is parked on a level surface and securely supported with jack stands.
Disconnect the battery if any electrical components will be removed.

2. Tire Inspection

Remove the wheel covers or hubcaps if equipped.
Inspect each tire for damage or uneven wear patterns.
Replace any damaged tires with new ones if necessary.

3. Wheel Balancing

Remove the wheels from the vehicle using a socket set.
Mount each wheel on a wheel balancing machine to identify imbalances.
Add wheel weights as needed to achieve proper balance.
Reinstall wheels and torque bolts to manufacturer specifications (usually around 100-120 ft-lbs).

4. Suspension and Alignment Check

Visually inspect all suspension components for wear or damage.
Replace any worn parts (e.g., control arms, bushings) with OEM or quality aftermarket parts.
Perform a four-wheel alignment using an alignment machine to ensure proper settings.

5. Final Assembly

Reinstall any removed components (e.g., wheel covers).
Reconnect the battery.
Ensure all tools are removed from the work area.
