Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a level surface and the engine is turned off.
Safety: Engage the parking brake and use wheel chocks.

2. Inspect and Replace CV Joints (if necessary)

Remove the wheel:
- Use a lug wrench to loosen the lug nuts.
- Lift the vehicle using a jack and secure it with jack stands.
- Remove the lug nuts and wheel.
Inspect the CV joint:
- Check for torn boots or leaking grease.
- If damaged, proceed to replace the CV joint.
Replace the CV joint:
- Remove the axle nut using a socket wrench.
- Disconnect any retaining clips and gently pull the CV joint from the transmission.
- Install the new CV joint by reversing the removal steps.
- Torque the axle nut to the manufacturer's specifications (typically 150-200 ft-lbs).

3. Inspect and Replace Suspension Components (if necessary)

Identify worn suspension parts:
- Look for cracks or excessive play in control arms, ball joints, and tie rods.
Remove and replace the damaged parts:
- For control arms:
  - Remove bolts securing the control arm to the chassis and the steering knuckle.
  - Install the new control arm and torque the bolts to the manufacturer's specifications (usually around 80 ft-lbs).
- For ball joints:
  - Remove the knuckle and unbolt the ball joint.
  - Install the new ball joint and secure it, ensuring proper torque settings.
Reassemble and recheck alignment:
- After replacing any parts, reattach the wheel and lower the vehicle.
- It's advised to get a wheel alignment after suspension work.
