My power steering is VERY hard, especially at low speeds and in reverse. Sometimes it acts likes there is no brake assist (seldom, but possibly related). There is a seep (not really a leak) in power steering hose I replaced last year. Seep may be because the hose is pressuring up so strongly. (?) I have replaced a hose a needle valve type thing in the pump and that seemed to help. That fixed the issue but it has returned.
My car has an automatic transmission.
