Solution

1. Preparation

Tools Required: Jack and jack stands, tire iron, torque wrench, socket set, wheel balancer, alignment machine.
Ensure the vehicle is parked on a level surface and the engine is off.
Use the jack to lift the vehicle and secure it with jack stands.

2. Tire Inspection and Balancing

Sub-steps:
1. Remove the wheels using a tire iron.
2. Inspect each tire for uneven wear or bulges; replace if necessary.
3. Balance each wheel using a wheel balancer.
4. Reinstall the wheels, tightening lug nuts to manufacturer specifications using a torque wrench.

3. Driveshaft and CV Joint Inspection

Sub-steps:
1. Inspect the driveshaft for any visible damage or excessive play by shaking it side to side.
2. Check CV joints for torn boots or grease leakage; replace if damaged.
3. If applicable, replace the entire driveshaft assembly if it shows signs of wear or damage.

4. Engine and Transmission Mount Inspection

Sub-steps:
1. Visually inspect the engine and transmission mounts for cracks or separation.
2. Use a pry bar to apply pressure to the mounts and check for excessive movement.
3. Replace any worn or damaged mounts with new parts.

5. Suspension Component Check

Sub-steps:
1. Inspect struts and shocks for leaks or damage.
2. Check bushings for signs of wear or cracking.
3. Replace any worn suspension components as necessary.
