I've actually never had one come back with a leak. If replacing the sector seal, always check the bushing as well. I always make sure all shaft seal surfaces are polished and everything is properly adjusted and as I said, I've never failed to stop a leak in a box.I have never had any luck resealing saginaw boxes,so I just got a reman from NAPA.$275 CND + $200 core charge,so I got it back in a hurry!The only issue so far was the return line,it was rusted and twisted off.The only sources around here were Mopar at $42 one day away or Canadian Tire at $27 a couple of days away,I'll post the part # and manufacturer when I get it,it seems that most parts chains can't source the o-ring type tube that this pump takes.So if you are going to go this route,make sure you have the hoses or be prepared to have the truck sit for a couple of days.
Try some Lucas Power Steering Stop Leak first. Evacuate the reservoir with a turkey baster. You can probably pull about 4 ounces of PS fluid out. Replace what you removed with the Lucas PSSL, then replenish as the level drops with more Lucas. If the leak is bad it may take two bottles to fix it.my steering box is leaking at a pretty good rate, and i was wondering if anyone found a good replacement for a resonable price?
