My trusty old B1700 with 1800 hours has been very good to me. It seems that, out of the blue, the steering turns hard left (very easily) and it's very difficult to turn right. I did some troubleshooting. Hydraulic fluid is within range. To eliminate linkage, I disconnected the drag link. Still, pulls hard left. From my research, sounds like it could be the power steering pump? Any thoughts or suggestions for continued TS'ing?
