  3. Reconnect the return line and fill with fresh power steering fluid.

3. Inspect and Replace CV Joints

Raise the vehicle using a jack and secure it with jack stands.
Remove the wheel to access the CV joint and axle.
Inspect the CV boot for tears or leaks; replace if damaged:
- Tools Required: Socket set, pry bar, CV joint puller.
- Sub-steps:
  1. Remove the axle nut and detach the CV joint from the hub.
  2. Replace the CV joint if worn; install new grease and boot.
  3. Reinstall the axle and torque the nut to the manufacturer's specification.

4. Inspect and Replace Wheel Bearings

Remove the wheel and brake components to access the hub.
Check for play in the wheel bearing by shaking the wheel.
If the bearing is worn, replace it:
- Tools Required: Bearing puller, socket set.
- Sub-steps:
  1. Remove the hub assembly from the steering knuckle.
  2. Use the bearing puller to extract the old bearing.
  3. Install the new bearing and reassemble components.
