Solution

1. Preparation

Ensure the vehicle is parked on a level surface and the engine is off.
Gather necessary tools and safety equipment.
Tools Required: Jack and jack stands, socket set, torque wrench, flashlight.

2. Inspect and Replace Suspension Components

Inspect Control Arms and Bushings:
- Use the flashlight to check for cracks or tears in the bushings.
- If damaged, proceed to remove and replace control arms.
Remove Control Arm:
- Loosen the bolts using the socket set.
- Remove the control arm from the vehicle.
Install New Control Arm:
- Position the new control arm and hand-tighten bolts.
- Torque the bolts to the manufacturer’s specifications (typically around 50-60 Nm, but refer to the service manual for exact values).

3. Check and Repair Steering Linkage

Inspect Steering Components:
- Look for wear in tie rod ends and the steering rack.
Replace Damaged Parts:
- If any parts are found to be worn, use the socket set to remove them and install new components.

4. Examine and Replace CV Joints

Inspect CV Joints:
- Check for tears in the CV boots or any grease leakage.
Replace CV Joint if Necessary:
- Remove the wheel and brake components to access the CV joint.
- Use the socket set to detach it from the axle.
- Install the new CV joint, ensuring it’s properly seated and secured.

5. Test Wheel Bearings

Check for Play:
- Spin the wheel by hand; listen for noise.
- If play is detected, remove the wheel bearing.
Replace Wheel Bearing:
- Use the appropriate puller tool to remove and replace the bearing, ensuring it is pressed in correctly.
