Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a flat surface and the parking brake is engaged.
Disconnect the battery to ensure safety while working on electrical components.

2. Tire Inspection and Balancing

Sub-steps:
- Inspect each tire for uneven wear and proper inflation. Inflate to the manufacturer’s recommended PSI if necessary.
- If uneven wear is found, rotate or replace the tires as needed.
- Use a wheel balancer to check and balance the wheels. Adjust weights as needed to ensure proper balance.

3. Suspension Component Inspection

Sub-steps:
- Visually inspect suspension components (control arms, bushings, struts, shocks) for any signs of wear or damage.
- Replace any worn or damaged components with OEM or high-quality aftermarket parts.
- Consider performing an alignment after replacing any suspension components.

4. Driveshaft and Axle Examination

Sub-steps:
- Inspect the driveshaft for any signs of damage, bending, or imbalance.
- Check the universal joints (U-joints) for play or wear; replace if necessary.
- Examine the axles for any signs of damage or excessive play, replacing them if needed.

5. Mounts Inspection

Sub-steps:
- Visually inspect the engine and transmission mounts for cracks or excessive wear.
- If mounts are found to be damaged, replace them with new mounts.
- Ensure all bolts are torqued to manufacturer specifications upon installation.
