A couple of years back my power steering pump went kaput. Fortunately I was able to locate a replacement for $50. All has been well until a couple of weeks ago. Now my power steering is a bit jerky at idle and when wheels are fully turned. It's tolerable now but I don't expect it to heal itself. My question is --- replace or rebuild? I know nothing about rebuilding these pumps but am pretty good at following instructions. Could it be a simple filter and seal replacement, or should I try to locate another donor pump? Any words of wisdom are appreciated.
