Solution

1. Preparation

Ensure the vehicle is on a flat surface and securely parked.
Disconnect the battery to prevent electrical shorts.
Gather all necessary tools and parts.

2. Check and Top Off Power Steering Fluid

Locate the power steering fluid reservoir.
Remove the cap and check the fluid level; it should be between the minimum and maximum marks.
If low, add the recommended power steering fluid (consult the owner’s manual for specifications).

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

Locate the power steering pump and disconnect the fluid lines using a line wrench.
Remove the mounting bolts securing the pump to the engine.
Install the new power steering pump in reverse order, ensuring all bolts are torqued to manufacturer specifications.
Reconnect fluid lines and bleed the power steering system by turning the steering wheel from lock to lock with the engine running.

4. Inspect and Replace Steering Rack (if necessary)

Raise the vehicle using a jack and secure it with jack stands.
Disconnect the steering column from the steering rack by removing the universal joint.
Remove the mounting bolts securing the steering rack to the subframe.
Slide the old steering rack out and install the new rack in reverse order, ensuring proper alignment.
Refill the power steering fluid and bleed the system.

5. Reconnect Battery and Test

Reconnect the battery and start the vehicle.
Check for leaks around the power steering pump and steering rack.
Test the steering operation at low speeds to ensure the issue is resolved.
