Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Disconnect the battery if necessary to prevent electrical issues.

2. Inspect and Replace CV Joints

Lift the Vehicle: Use a hydraulic jack to raise the vehicle and secure it with jack stands.
Remove the Wheel: Use a socket set to remove the lug nuts and take off the wheel.
Inspect CV Joint: Check for torn boots and excessive play.
Replace if Damaged:
- Remove the axle nut with a socket.
- Detach the axle from the hub assembly.
- Replace the CV joint or entire axle as necessary.
- Reinstall the axle and torque the axle nut to the manufacturer's specification (typically around 200-250 Nm).

3. Check and Replace Wheel Bearings

Inspect Wheel Bearings: Spin the wheel by hand to listen for grinding noises.
Replace if Noisy:
- Remove the brake caliper and rotor.
- Use a bearing puller to remove the old bearing from the hub.
- Install the new bearing and reassemble components.
- Torque caliper bolts to manufacturer’s specifications (usually 30-40 Nm).

4. Assess Suspension Components

Visual Inspection: Look for signs of wear or damage on struts, shocks, and control arms.
Replace Worn Components:
- Remove the necessary components (e.g., strut assembly) as per repair manual instructions.
- Install new parts ensuring all bolts are torqued to manufacturer specifications.
