I have a steering pump that was remanufactured by Lee Manufacturing (not longer in business) in early 2015. I used it for about 2 years (~1,000 miles) with no noise issues. When installing it, I followed the recommended purge procedure and used only transmission Type F fluid. I checked the fluid level often and it was within range.
Last week I took the car for a ride and after making a U-turn the pump started to make the typical "cavitation" noise. Low noise when driving straight, heavier noise when turning. When I parked the car and after turning the engine off, a lot of foamy steering fluid came out of the fill tube. I tried several times, and it would leak every time only after the engine was stopped.
I let it rest for a few days, refilled it, and purged it by turning the steering end-to-end several times. Drove it for a few miles, turned the engine on and off several times. It didn't leak anymore, but still had a faint cavitation noise. Today, I took the car for a drive and the faint cavitation noise was still there. When turning the steering the noise will get higher. Then I turned the steering couple times back-and-forth and the noise got worse. After I turned the engine off I got the leak again through the fill tube. I have the feeling that there is something wrong with the pump. Right now there are no other leaks in the system besides the one out of the fill tube after then engine is turned off. All the hoses are new, the steering box was also remanufactured by Lee and shows no obvious leaks. The only piece left from the old system is the cooler. Any ideas? When the pump was remanufactured they stated that they calibrate the pump for the "heavier valve" of the modified steering box. How is this calibration done? I have a "new" remanufactured pump that I could try, but I am wondering if I really need this calibration.
