Recently i replaced the rear struts. The new struts are heavy duty to support my 22 inch runs. They lack the plug outlet to which were on the top of the original struts. My first time riding on the they sat high and very stiff. Once I turned the car off the car sat low and since riding it again they have not lifted back up. The compressor stays on for a lengthy amount of time once the car us off. Is it possible I have a major leak in the hose from the compressor leading to the struts? How do I fix this problem?
