Solution

1. Preparation

Gather all necessary tools and parts.
Disconnect the battery to ensure safety while working on electrical components.

2. Check and Refill 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 markings.
If low, use the manufacturer-recommended power steering fluid to refill.
Replace the cap securely.

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

Remove the serpentine belt using a belt tensioner tool.
Disconnect the power steering lines from the pump using a suitable wrench.
Unbolt the power steering pump from its mount (use a socket set) and remove it.
Install the new power steering pump by reversing the removal steps. Ensure all bolts are torqued to the manufacturer's specification (refer to service manual for torque values).
Reattach the power steering lines and serpentine belt.

4. Inspect Steering Column and Linkage

If stiffness persists, inspect the steering column for binding or obstruction.
Ensure all joints in the steering linkage are lubricated and free from corrosion.
Replace any worn or damaged components.

5. Reconnect Battery and Test

Reconnect the battery terminals.
Start the vehicle and turn the steering wheel from lock to lock to bleed any air from the system.
