Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Ensure the vehicle is cool and disconnect the battery if necessary for safety.

2. Tire Balancing

Tools Required: Wheel balancer, tire iron, jack, jack stands.
Remove the wheel and tire assembly using a tire iron.
Mount the wheel on the wheel balancer and spin it to identify heavy spots.
Add wheel weights as needed to balance the tire.
Reinstall the wheel and torque the lug nuts to the manufacturer’s specifications (usually around 75-85 ft-lbs).

3. Tire Inspection and Replacement

Inspect tires for any signs of damage or excessive wear.
If tires are damaged or worn unevenly, replace them with new tires.
Ensure all tires are inflated to the recommended pressure.

4. Suspension Inspection and Repair

Tools Required: Wrench set, socket set, torque wrench.
Visually inspect all suspension components for signs of wear or damage.
Replace any worn or damaged parts, including shocks, struts, or bushings.
Follow manufacturer specifications for torque settings on all components.

5. Wheel Runout Adjustment

Tools Required: Dial indicator, jack, jack stands.
Remove the wheel from the hub.
Use the dial indicator to measure the runout on the wheel and hub assembly.
If the runout exceeds specifications, assess whether the wheel is bent or if the hub is damaged, and replace as necessary.
