Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a flat surface and securely lifted if needed.
Disconnect the battery to avoid any electrical issues during repair.

2. Check Power Steering Fluid

Locate the power steering fluid reservoir.
Remove the cap and inspect fluid levels; top up with the manufacturer-recommended fluid if low.
If the fluid is dark or contaminated, proceed to flush the system.

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

Remove any components obstructing access to the power steering pump (e.g., belts).
Disconnect the power steering lines from the pump using a wrench.
Remove mounting bolts securing the pump and take it out.
Install the new pump by reversing the removal process, ensuring all connections are secure.
Refill the power steering fluid reservoir to the appropriate level.

4. Inspect Steering Rack

If stiffness persists, inspect the steering rack for damage.
Remove the steering rack from the vehicle by disconnecting it from the steering column and suspension components.
Replace the steering rack if any binding or damage is found.

5. Reconnect Battery and Test

Reconnect the battery and ensure all connections are secure.
Start the vehicle and cycle the steering wheel to check for smooth operation.
Test drive the vehicle to confirm that the steering feels normal.
