Visual Inspection
A visual inspection of the steering system and the components is the first step when you identify a problem.

Do not check for leaks with your hands. Pin hole (very small) leaks can result in a high velocity oil stream that will be invisible close to the hose. This oil can penetrate the skin and cause personal injury. Use cardboard or paper to locate pin hole leaks. |

- Check all oil lines and connections for damage.
- Check the pump and connections for damage and leaks.
- Follow the pump lines to the tank and valves. Check the lines for damage and leaks.
- Check the oil tank for damage and leaks.
- Check the tank oil level.
- While the engine is running use the oil sampling valve in order to get an oil sample. The steering solenoid and relief valve has an oil sampling valve. Check for air bubbles in the oil sample.

- Remove the filter elements. Check for particles that were removed from the oil by the filter elements. A magnet will separate ferrous particles from nonferrous particles (piston rings, O-rings, or seals).
