Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface with the engine off.
Disconnect the battery to prevent any electrical issues (if applicable).

2. Check Power Steering Fluid

Locate the power steering fluid reservoir and remove the cap.
Inspect the fluid level; if low, top off with the recommended power steering fluid (check owner’s manual for specifications).
If the fluid appears dirty or contaminated, proceed to replace it.

3. Inspect and Replace Power Steering Fluid

Place a drain pan under the power steering pump.
Disconnect the return line from the pump and allow old fluid to drain.
Reconnect the return line and refill the reservoir with new power steering fluid.
Purge air from the system by turning the steering wheel from lock to lock several times.

4. Inspect Components

Visually inspect the power steering pump, hoses, and connections for any signs of wear, cracks, or leaks.
Replace any damaged components as necessary. For the pump, remove it by:
- Disconnecting the power steering lines and electrical connectors.
- Unbolting the pump from its mounting bracket.
- Installing the new pump and reconnecting all lines and connectors.

5. Check Steering Column

If the stiffness persists, remove the steering column cover to inspect for any obstructions.
Ensure the steering column shaft is properly lubricated and free of debris.
If damaged, replace the steering column assembly.
