Stomach ulcers are sores that form in the lining of your stomach due to erosion of the protective mucus layer.

There is a pump which supplies pressure, a steering gear which is powered by the pressure and hoses that connect it all. There is also power steering fluid which is the life-blood of the system.

Power steering fluid cools, cleans, lubricates, conditions seals and transmits the hydraulic force used to assist steering.
