Solution

1. Preparation

Gather tools and parts needed.
Ensure the vehicle is safely parked on a level surface with the parking brake engaged.
Wear safety glasses and gloves.

2. Tire Inspection and Adjustment

Tools Required: Tire pressure gauge, jack, jack stands, lug wrench
Check tire pressure and inflate to recommended levels.
Inspect tires for any bulges, cuts, or uneven wear. Replace if necessary.

3. Wheel Balancing

Tools Required: Wheel balancer
Remove the wheels from the vehicle using the lug wrench.
Place the wheels on a wheel balancing machine to determine imbalance.
Add wheel weights as needed to correct balance and reinstall the wheels.

4. Suspension Inspection

Tools Required: Socket set, torque wrench, pry bar
Lift the vehicle using a jack and secure with jack stands.
Visually inspect shocks and struts for leaks or damage.
Use a pry bar to check for play in bushings and joints. Replace any worn components.

5. Hub Assembly and Bearing Check

Tools Required: Socket set, torque wrench
Remove the wheel hub assembly as needed to access the bearings.
Inspect bearings for smooth operation and check for any noise or play.
Replace bearings if they are worn out.

6. Reassemble and Torque

Reinstall all components, ensuring to torque lug nuts to the manufacturer’s specifications (typically around 80-100 ft-lbs).
Lower the vehicle and perform a final safety check of all components.
