I'll try to keep this short. I lost power steering that would intermittently return at higher RPM. First I bought a new PS pump, didn't work. Then I rebuilt steering box, didn't work. Then bought new steering box, still doesn't work. Disconnected steering shaft, spins easy. Jacked up the wheels and disconnected drag link, ab;le to turn by hand with ease (ie no binding anywhere) Only thing I can think of is that I was sold a bad pump. What are your opinions/suggestions? Thanks.
