Solution

1. Preparation

Gather tools and parts.
Ensure the vehicle is parked on a flat surface and securely lift it using a jack and jack stands.
Tools Required: Socket set, torque wrench, pry bar, OBD-II scanner (if needed for diagnostics).

2. Inspect and Replace CV Joints

Sub-steps:
1. Remove the wheel to access the CV joint.
2. Inspect the CV joint for damage or torn boot.
3. If damaged, remove the axle nut using a socket and break bar.
4. Disconnect the lower control arm to free the CV joint from the hub.
5. Replace the CV joint with a new one and reassemble by reversing the steps.
Torque Values: Re-torque the axle nut to manufacturer specifications (typically around 30-40 Nm).

3. Replace Worn Suspension Components

Sub-steps:
1. Identify any worn bushings or struts during the visual inspection.
2. Remove the affected suspension component by unbolting it from the chassis and hub.
3. Install the new suspension component and ensure all fasteners are tightened to specification.
Tools Required: Torque wrench, socket set.

4. Inspect and Replace Wheel Bearings

Sub-steps:
1. Remove the wheel and brake components to access the wheel bearing.
2. Check for play in the bearing by rocking the wheel.
3. If necessary, remove the hub assembly to replace the bearing.
4. Press in the new bearing and reassemble all components.
Torque Values: Follow manufacturer specifications for hub assembly bolts.
