Solution

1. Preparation

Gather necessary tools and parts before starting.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the negative battery terminal to ensure safety while working.

2. Tire Inspection and Balancing

Check Tire Pressure: Use a tire pressure gauge to ensure all tires are inflated to the manufacturer's recommended PSI.
Inspect for Damage: Visually inspect all tires for cuts, bulges, or uneven wear patterns.
Balance Tires: If tires are unbalanced, take them to a tire shop for balancing. This may involve removing and re-installing the wheels.

3. Drivetrain Inspection

Visual Inspection of Driveshaft: Inspect the driveshaft for any visible signs of wear, bends, or damage.
Check CV Joints: Look for torn boots or excessive play in the CV joints. Replace any damaged joints.
Secure Mounts: Inspect engine and transmission mounts for cracks or excessive wear. Replace if necessary.

4. Suspension Component Check

Inspect Struts and Shocks: Look for any leaks or signs of wear. Replace worn components as needed.
Check Bushings: Examine all suspension bushings for cracks or degradation. Replace any that are damaged.
