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 for safety.

2. Inspect and Replace Power Steering Fluid

Locate the power steering reservoir.
If the fluid is low or dirty, drain the existing fluid using a turkey baster.
Refill with manufacturer-recommended power steering fluid until it reaches the correct level.
Reconnect the battery terminal.

3. Replace Worn CV Joints (if necessary)

Lift the front of the vehicle using a jack and secure it with jack stands.
Remove the wheel to access the CV joint.
Disconnect the CV joint from the axle by removing the retaining bolts using a socket set.
Replace with a new CV joint, ensuring to properly secure it with bolts to the manufacturer’s torque specifications.

4. Check Wheel Bearings

With the wheel removed, grasp the tire at the 12 and 6 o'clock positions and shake to check for play.
If play is detected, remove the wheel bearings and replace them with new ones.
Properly torque the hub nut to the specified value for the model.

5. Inspect Steering Rack and Pinion

Check for any visible damage or excessive wear on the steering rack.
If damage is found, replace the steering rack with a new unit.
Ensure all connections are tight and secure.
