Solution

1. Preparation

Gather tools and parts required for inspection and repair.
Ensure the vehicle is parked on a flat surface and securely lift the vehicle using a jack and jack stands.
Disconnect the negative battery terminal to prevent electrical issues.

2. Inspect and Balance Tires

Remove the wheel covers if applicable, and loosen the lug nuts on the affected wheels.
Lift the vehicle and remove the wheels.
Inspect tires for bulges, cracks, or uneven wear. Replace if necessary.
Have the tires balanced at a tire shop and ensure they are rotated if uneven wear is noticed.
Reinstall the wheels and torque the lug nuts to the manufacturer’s specifications (typically 100-120 ft-lbs).

3. Check Driveshaft and Mounts

Inspect the driveshaft for any visible damage or excessive play.
Replace the driveshaft if damaged. Use a torque wrench to secure bolts to the specified torque values.
Inspect engine and transmission mounts for cracks or excessive wear. Replace if necessary, ensuring proper alignment during installation.

4. Verify Suspension Components

Check all suspension components, including control arms, bushings, and joints for wear.
Replace any worn components with OEM parts, ensuring proper torque specifications are followed during installation.
Reassemble any disassembled parts and recheck alignment.
