Solution

1. Preparation

Gather tools: jack, jack stands, tire iron, OBD-II scanner, torque wrench, and a wheel balancer (if available).
Park the vehicle on a flat surface and engage the parking brake.

2. Tire Inspection and Balancing

Inspect Tires:
- Check each tire for uneven wear, bulges, or foreign objects.
- Measure tire pressure and inflate to the manufacturer's specifications if needed.
Balance Tires:
- Remove the wheel and tire assembly using the tire iron.
- Use a wheel balancer to correct any imbalances.
- Reinstall the wheel and torque the lug nuts to the manufacturer’s specifications.

3. Suspension Component Inspection

Visual Inspection:
- Raise the vehicle using a jack and secure it with jack stands.
- Inspect control arms, bushings, and struts for any signs of wear or damage.
Replace Components:
- If any parts are found defective, replace them as necessary following the manufacturer’s service manual for torque specifications.

4. Drivetrain and Engine Mounts

Inspect Driveshaft and CV Joints:
- Check for any signs of play or damage at the CV joints.
- If damaged, replace the CV joint or driveshaft as required.
Check Engine Mounts:
- Inspect mounts for cracks or excessive wear.
- Replace any worn or damaged engine mounts to reduce vibrations.
