Thanks for the link. That was some very interesting information. After reading it I think I may just sell my original power steering system and buy a blueprinted manual box and be done with it. I know r-p is better but I drove a 1982 M-B 240-D for about 250,000 miles and it had a recirculating-ball, rear-steer system that I really liked its feel. If I can get anything near that with the stock, blueprinted unit I'll just stay away from ALL those problems!
