Solution

1. Preparation

Gather necessary tools and ensure the vehicle is on a level surface.
Secure the vehicle with jack stands and remove the front wheels if needed.
Tools Required: Jack, jack stands, socket set, torque wrench.

2. Inspect and Replace CV Joints

Sub-steps:
1. Visually inspect the CV joints for cracks or tears in the rubber boot.
2. If damage is found, remove the axle nut using a socket and breaker bar.
3. Detach the CV axle from the hub assembly and remove it from the transmission.
4. Install the new CV joint/axle by reversing the removal process.
5. Torque the axle nut to the manufacturer’s specifications (typically around 150 ft-lbs).

3. Check and Replace Suspension Components

Sub-steps:
1. Inspect control arm bushings and ball joints for wear.
2. If damaged, remove the control arm by unbolting it from the frame and the wheel hub.
3. Replace with new bushings/ball joints and reassemble.
4. Torque all fasteners to the manufacturer’s specifications.
5. Reinstall the wheel and lower the vehicle.

4. Wheel Bearing Inspection

Sub-steps:
1. Spin the wheel to check for roughness or grinding noises.
2. If faulty, remove the wheel and brake assembly.
3. Use a bearing puller to remove the old wheel bearing.
4. Install the new bearing and reassemble the brake and wheel assembly.
5. Torque the wheel lug nuts to the specified value (typically 80-100 ft-lbs).
