01 PT cruiser, no power steering at idle. Works when you are going down the road and have at least 2000 rpms, yet it still whines. I replaced the pump with a used pump from a wrecking yard, I don't know if its a good pump because the system doesn't work. I also cleaned the mesh filter in the reservoir. At idle, the power steering works if you turn the wheel very slowly(it also whines loudly), as if the system has trouble building pressure? I guess at this point, its a bad pump or a bad rack, or both. I'm poor will the replacement seal kits fix the rack and or pump?
