Solution

1. Preparation

• Gather tools: jack, jack stands, socket set, torque wrench, pry bar, and safety glasses.
• Ensure the vehicle is on a flat surface and engage the parking brake.

2. Inspect and Replace CV Joints

• Inspect CV Boots:
  • Remove the wheel to access the CV joints.
  • Check for any tears or leaks in the CV boots.
• Replace CV Joint:
  • If the CV joint is damaged, remove the axle nut using the socket set.
  • Disconnect the lower control arm and sway bar link if necessary.
  • Slide the CV axle out of the transmission or differential.
  • Install the new CV joint by reversing the removal steps.
  • Torque the axle nut to the manufacturer's specifications (typically around 30-50 ft-lbs).

3. Suspension Component Repair

• Check and Replace Worn Components:
  • Inspect the tie rods, ball joints, and control arms for wear.
  • Replace any worn components by removing bolts and using a pry bar if necessary.
  • Ensure all new parts are torqued to specifications.

4. Wheel Bearing Inspection

• Check Wheel Bearings:
  • Spin the wheel while it is off the ground to listen for noise.
  • If noise is present, remove the wheel bearing assembly.
  • Replace with a new bearing if necessary, ensuring proper alignment during installation.
