Safety Warning: Ensure the vehicle is parked on a level surface and the engine is off before inspecting.

2. Inspect the Power Steering Fluid Reservoir

Locate the power steering fluid reservoir (refer to the owner's manual if needed).
Remove the reservoir cap and wipe the dipstick clean.
Reinsert the dipstick and check the fluid level against the recommended marks.

With the engine running, turn the steering wheel from lock to lock and observe the steering rack.
Look for any fluid seeping from the seals or joints.
If a leak is found, mark the area for repair.

5. Replace Damaged Components

If any hoses or the power steering pump are found to be leaking:
- Hose Replacement:
  - Disconnect the old hose using appropriate wrenches.
  - Install the new hose and tighten securely.
- Pump Replacement:
  - Disconnect the power steering pump from the vehicle.
  - Install the new pump and connect all hoses securely.
Refill the power steering fluid reservoir with the appropriate fluid type.
