Solution

1. Preparation

• Gather tools and safety equipment.
• Ensure the vehicle is parked on a level surface and engage the parking brake.
• Use wheel chocks to secure the vehicle.

2. Lift the Vehicle

• Use a floor jack to lift the front of the vehicle.
• Secure it with jack stands for safety.

3. Inspect and Replace CV Joint (if necessary)

• Inspect the CV Joint:
  • Remove the front left wheel using a socket set.
  • Inspect the CV boot for cracks or tears. If damaged, proceed to replace the CV joint.
• Replace the CV Joint:
  • Remove the axle nut using a socket and breaker bar.
  • Disconnect the lower control arm and any components obstructing access to the CV joint.
  • Slide the old CV joint out of the transmission and insert the new CV joint.
  • Reassemble all components and torque bolts to manufacturer specifications.

4. Check and Replace Power Steering Fluid (if necessary)

• Inspect Fluid Level:
  • Check the power steering fluid reservoir; if low, top up with the manufacturer-recommended fluid.
• Replace Fluid:
  • Use a turkey baster to remove old fluid from the reservoir.
  • Fill with new power steering fluid and cycle the steering wheel to eliminate air bubbles.

5. Examine Suspension Components

• Inspect Control Arms and Bushings:
  • Visually inspect control arms for cracks or excessive wear.
  • Replace any worn bushings with new ones.
  • Reassemble and torque bolts as per specifications.
