Re: Power Steering Control Valve
I'm not mechanically inclined, hence hiring a mechanic to do the work. I'll give it a shot, however.
We Initially replaced the power steering piston, the control valve and hoses due to the piston failing and the control valve leaking. The rebuilt piston has held up, but the rebuilt control valve started leaking concurrently with squealing, thumping and bumping when turning the steering wheel. I called the company that provided the rebuilt components (through retail supplier) and described the symptoms, and they concurred that the valve seals had apparently not held up. Ordered another rebuilt control valve and that project is under way at repair shop. I'm just fishing for parts that may be more readily available if this effort also fails.
Hope that helps.
