Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the 12V battery for safety when working on electrical components.

2. Tire Inspection and Rotation

Sub-steps:
- Remove the wheel covers if applicable.
- Inspect all tires for damage, punctures, or bulges.
- Rotate tires if uneven wear is detected, moving front tires to the rear and vice versa.
Tools Required: Jack, jack stands, tire iron, torque wrench.

3. Wheel Balancing

Sub-steps:
- Remove the wheels from the vehicle using a tire iron.
- Mount each wheel on the balancing machine and follow the machine's instructions for balancing.
- Add weights as necessary to achieve balance.
- Reinstall the balanced wheels on the vehicle, ensuring to torque the lug nuts to the manufacturer's specifications (typically 100-120 ft-lbs).
Tools Required: Tire balancing machine, torque wrench.

4. Wheel Alignment

Sub-steps:
- Use an alignment tool to measure the current wheel angles.
- Adjust the toe, camber, and caster as needed to bring them within the manufacturer's specifications.
Tools Required: Wheel alignment machine.

5. Suspension Inspection and Repair

Sub-steps:
- Visually inspect control arms, bushings, and shocks for signs of wear or damage.
- Replace any worn components with OEM parts using appropriate tools.
Tools Required: Socket set, wrenches, possibly a spring compressor.
