Solution

1. Preparation

Gather tools and parts: OBD-II scanner, socket set, jack and jack stands, torque wrench, new CV joint or wheel bearing (if applicable), and power steering fluid.
Ensure the vehicle is parked on a level surface, and engage the parking brake.
Disconnect the battery if necessary for safety.

2. Inspect and Replace CV Joints

Inspect CV Joints:
- Remove the wheel to access the CV joint.
- Check for torn boots or grease leakage.
Replace CV Joint (if damaged):
- Remove the axle nut using the socket set.
- Detach the axle from the hub assembly.
- Remove the CV joint from the axle shaft.
- Install the new CV joint and reassemble in reverse order.
- Torque the axle nut to manufacturer specifications (typically around 200 Nm).

3. Inspect and Replace Wheel Bearings

Remove Wheel:
- Using a jack, lift the vehicle and secure it with jack stands.
- Remove the wheel to access the bearings.
Check Bearing Condition:
- Spin the hub and listen for grinding sounds, or feel for roughness.
Replace Wheel Bearing (if necessary):
- Remove the brake caliper and rotor.
- Use a bearing puller to extract the old bearing from the hub assembly.
- Install the new bearing and reassemble in reverse order.
- Torque the caliper and rotor bolts to manufacturer specifications.

4. Inspect Suspension Components

Visual Inspection:
- Look for damaged bushings, struts, or control arms.
- Shake the components to check for play or movement.
Replace Damaged Components (if necessary):
- Remove the affected component following manufacturer service procedures.
- Install the new part and torque all bolts to specifications.
