Solution

1. Preparation

Gather tools and parts required for the repair.
Park the vehicle on a flat surface and set the parking brake.
Gather necessary safety gear, including gloves and safety goggles.

2. Tire Balancing

Remove the wheels from the vehicle using a jack and jack stands.
Take the wheels to a tire shop or use a tire balancing machine to check and correct the balance.
Reinstall the wheels and torque the lug nuts to the manufacturer’s specifications (usually around 80-100 ft-lbs).

3. Tire Inspection and Replacement

Inspect each tire for damage and tread depth.
If tires are damaged or excessively worn, replace them with new tires.
Ensure new tires are properly mounted and balanced.

4. Alignment Check

Once the tires are balanced, check the alignment with an alignment tool.
Adjust the alignment settings to meet the manufacturer's specifications (typically, toe, camber, and caster angles).
Perform a test drive to verify the alignment correction.

5. Suspension Inspection and Repair

Visually inspect all suspension components for signs of wear or damage.
Replace any worn or damaged parts, such as ball joints, tie rods, or control arms.
Reassemble any components that were removed for inspection and tighten to specified torque settings.
