Solution

1. Preparation

Tools Required: Socket set, wrench set, power steering fluid, rags, leak detection dye (optional).
Safety Warnings: Disconnect the battery before starting work. Allow the engine to cool before inspecting the power steering system.

2. Check and Refill Power Steering Fluid

Locate the power steering fluid reservoir.
Remove the cap and check the fluid level. If low, add the appropriate type of power steering fluid as specified in the owner’s manual.
Inspect the fluid for contamination; if dirty, proceed to fluid replacement.

Place a drain pan under the power steering fluid reservoir.
Disconnect the return hose from the power steering pump.
Allow old fluid to drain into the pan.
Reconnect the hose and fill the reservoir with new power steering fluid.
Start the engine and turn the steering wheel from lock to lock to purge air from the system.

4. Inspect Power Steering Pump

Locate the power steering pump and inspect for any visible leaks.
Check the belt connected to the pump for wear or looseness. Replace if necessary.
If the pump is noisy or damaged, remove the pump by:
- Disconnecting the hoses and electrical connectors.
- Unbolting the pump from its mounting.
- Installing the new pump in reverse order.

5. Inspect Steering Rack

Check the steering rack for any signs of fluid leaks.
If a leak is found, replace the steering rack assembly by:
- Removing the steering column connection.
- Disconnecting the tie rods.
- Unbolting and removing the rack.
- Installing the new rack and reassembling all components.
