Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a level surface, and the ignition is off.
Disconnect the negative battery terminal.

2. Check and Refill Power Steering Fluid

Locate the power steering fluid reservoir.
Remove the cap and check fluid level; if low, add the recommended power steering fluid until it reaches the proper level.
If the fluid is dark or contaminated, proceed to replace it.

3. Inspect and Replace Power Steering Pump (if necessary)

Tools Required: Socket set, wrench, fluid catch pan
Use the socket set to remove the bolts securing the power steering pump.
Disconnect the hoses from the pump and let any remaining fluid drain into the catch pan.
Install the new power steering pump by reversing the removal process, ensuring all connections are tight.
Refill the power steering reservoir with fluid.

4. Check Steering Rack and CV Joints

Inspect the steering rack for any visible damage or play.
Check the CV joints for signs of wear, such as torn boots or excessive movement.
If damaged, replace the steering rack or CV joint as necessary.

5. Reassemble and Test

Reassemble any components removed during the inspection.
Reconnect the negative battery terminal.
Start the vehicle and turn the steering wheel from lock to lock to bleed any air from the system.
