Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and secured with wheel chocks.
Disconnect the battery if electrical components will be serviced.

2. Tire Inspection and Balancing

Tools Required: Tire pressure gauge, jack and jack stands, wheel balancer.
Inflate all tires to the recommended pressure (check owner's manual).
Inspect each tire for damage; replace any damaged tires.
Remove the wheels, and mount them on a wheel balancer to check for imbalance.
Adjust weights as needed to balance the wheels properly.

3. Suspension Inspection

Tools Required: Torque wrench, socket set, pry bar.
Visually inspect the suspension components for any signs of wear or damage.
Check the tightness of all suspension bolts and nuts using a torque wrench, ensuring they meet the manufacturer's specifications.
Replace any worn or damaged components, such as bushings or struts, as necessary.

4. Driveline Inspection

Tools Required: Socket set, torque wrench, pry bar.
Inspect the driveshaft for any signs of damage or excessive play.
Check the universal joints for wear by moving the driveshaft up and down; replace if necessary.
Ensure that the driveshaft is properly aligned and secured.
