Solution

1. Tire Inspection

Tools Required: Tire pressure gauge, jack, lug wrench
Sub-steps:
1. Use a tire pressure gauge to check the air pressure in all tires and inflate as necessary.
2. Visually inspect each tire for bulges, cuts, or objects lodged in the tread.
3. Rotate the tires if uneven wear is present and replace any damaged tires.

2. Suspension Component Replacement

Tools Required: Socket set, torque wrench, jack stands
Sub-steps:
1. Lift the vehicle using a jack and secure it with jack stands.
2. Remove the wheel to access the suspension components.
3. Inspect the struts and shocks for leakage or damage. If damaged, remove the old strut/shock.
4. Install the new strut/shock, torque the mounting bolts to the manufacturer’s specifications (typically around 40-50 ft-lbs).
5. Reinstall the wheel and lower the vehicle.

3. Drivetrain Inspection

Tools Required: Socket set, pry bar, flashlight
Sub-steps:
1. Inspect the CV joints for any torn boots or play in the joints.
2. If the CV joint is damaged, remove the axle and replace it with a new one.
3. Check the axle shaft for any signs of wear or damage, replacing as necessary.
