Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Disconnect the negative battery terminal to ensure safety.

2. Inspect and Replace Power Steering Fluid

Locate the power steering fluid reservoir.
Remove the cap and check fluid level; if low, fill with the manufacturer's recommended fluid.
If the fluid is dark or contaminated, drain and replace it using a turkey baster or siphon.

3. Inspect and Replace CV Joints

Raise the front of the vehicle using jack stands.
Remove the front wheels using a socket set.
Inspect the CV boots for tears or leaks. If damaged, replace the CV joint assembly.
- Sub-steps:
  - Remove the axle nut using a socket.
  - Disconnect the lower control arm from the knuckle.
  - Slide the CV axle out of the transmission and replace it with a new one.
  - Reassemble all components in reverse order and torque to specifications (usually around 150 ft-lbs for the axle nut).

4. Check and Replace Wheel Bearings (if necessary)

With the wheel off, grab the wheel at 12 and 6 o'clock positions and check for play.
If play is detected, remove the brake caliper and rotor to access the wheel bearing.
Replace the wheel bearing by pressing it out and installing a new one using a bearing press.

5. Final Assembly

Reinstall the wheels and lower the vehicle.
Reconnect the negative battery terminal.
Torque the wheel lug nuts to the manufacturer's specifications (usually around 76 ft-lbs).
