Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Place wheel chocks behind the rear wheels for safety.

2. Inspect and Replace Worn Suspension Components

Remove Wheel:
- Use a jack to lift the vehicle and securely support it with jack stands.
- Remove the lug nuts with a socket set and take off the wheel.
Inspect Suspension Components:
- Check the control arms, bushings, and strut mounts for wear or damage.
- If any components are worn or damaged, proceed to replace them.
Replace Control Arm/Bushings (if necessary):
- Remove the bolts securing the control arm using a torque wrench.
- Replace the control arm or bushings with new parts.
- Torque the bolts to the manufacturer’s specifications.

3. Inspect and Replace CV Joint

Inspect CV Joint:
- Examine the CV joint boots for tears or leaks.
- If the boot is damaged, replace the entire CV axle.
Replace CV Axle (if necessary):
- Remove the axle nut using a socket.
- Disconnect the lower control arm from the knuckle to free the CV axle.
- Install the new CV axle and reassemble components, ensuring proper torque specifications.

4. Check Wheel Bearings

Inspect Wheel Bearings:
- Spin the wheel by hand to listen for grinding or roughness.
- If faulty, remove the hub assembly and replace the wheel bearings.
Reassemble:
- Reattach the hub assembly and torque bolts to specifications.

5. Reinstall Wheel

Place the wheel back on the hub, hand-tighten the lug nuts, and lower the vehicle.
Torque the lug nuts to the manufacturer’s specifications using a torque wrench.
