Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and engage the parking brake.
Disconnect the battery if working on the electrical system.

2. Tire Inspection and Balancing

Tools Required: Tire pressure gauge, tire balancing machine
- Check tire pressure and inflate to manufacturer specifications.
- Inspect tires for uneven wear or damage; replace if necessary.
- If tires are unbalanced, mount them on a tire balancing machine and adjust weights as needed.

3. Suspension Component Inspection

Tools Required: Jack and jack stands, socket set
- Raise the vehicle using a jack and secure it with jack stands.
- Inspect shock absorbers and struts for leaks or damage; replace if faulty.
- Check bushings for wear; replace if cracked or deteriorated.

4. Wheel Alignment Check

Tools Required: Alignment equipment
- Perform a wheel alignment using alignment equipment to ensure all wheels are aligned to specifications.

5. Driveshaft and CV Joint Inspection

Tools Required: Socket set, pry bar
- Inspect the driveshaft for any signs of wear or damage.
- Check the CV joints for torn boots or play; replace if damaged.

6. Wheel Bearing Inspection

Tools Required: Socket set, torque wrench
- Lift the vehicle and check for play in the wheel bearings by rocking the wheel.
- If play is detected, remove the wheel and hub assembly, and replace the wheel bearings as necessary, torquing to manufacturer specifications.
