Solution

1. Preparation

Gather the necessary tools and parts.
Park the vehicle on a flat, stable surface and engage the parking brake.
Disconnect the battery to ensure safety while working on the vehicle.

2. Inspect and Replace Tires (if necessary)

Sub-steps:
1. Remove each wheel by loosening the lug nuts with a socket wrench.
2. Inspect the tires for any damage or excessive wear; replace if necessary.
  - Tools Required: Jack, jack stands, socket set, tire pressure gauge.
3. Install new tires if needed, ensuring they are mounted correctly.

3. Wheel Balancing

Sub-steps:
1. Remove the wheel and take it to a tire shop for balancing.
2. Ensure they use a dynamic balancer to accurately measure the wheel's weight distribution.
3. Reinstall the balanced wheel back onto the vehicle.
  - Tools Required: Torque wrench (for proper lug nut torque).

4. Suspension Inspection and Repair

Sub-steps:
1. Visually inspect the suspension components for any signs of wear, including bushings and joints.
2. If any components are worn, replace them with OEM or quality aftermarket parts.
  - Tools Required: Wrenches, socket set, possibly a ball joint puller.
3. Reassemble the suspension components and ensure all bolts are torqued to specifications.

5. Wheel Alignment

Sub-steps:
1. Take the vehicle to a professional alignment shop.
