Solution

1. Tire Inspection and Repair

Check tire pressure: Ensure all tires are inflated to the recommended PSI.
Inspect tread: Look for uneven wear patterns; replace tires if necessary.
Balance tires: Use a wheel balancing machine to ensure proper balance.

2. Wheel Alignment

Perform alignment: Use an alignment machine to adjust the camber, caster, and toe settings to manufacturer specifications.

3. Engine and Transmission Mount Replacement

Remove old mounts:
- Disconnect the battery.
- Raise the vehicle and secure it on jack stands.
- Remove any components obstructing access to mounts.
Install new mounts:
- Position new engine/transmission mounts.
- Torque bolts to manufacturer specifications (typically 40-60 ft-lbs).

4. Driveshaft and Axle Inspection

Inspect driveshaft and axles:
- Check for any visible damage or wear.
- If damaged, replace with OEM parts.

5. Suspension Component Replacement

Check shocks/struts:
- Inspect for leaks or damage.
- Replace if necessary.
- Ensure all bushings are intact and replace worn ones.
