Power steering leak, help!
So, last spring I had a failure from rusted power steering lines. I replaced every line because they were all starting to look questionable. All good until the other day. My daughter had borrowed my truck, called to say all the PS fluid had leaked out and wouldn’t steer. After towing it home, I had a look see under there. Fluid everywhere, no way to see where it may have come from. I poured in 1/2 quart, and it just poured out, but I couldn't see from where it was coming because of blocked view. After using a fiberoptic scope, I managed to see the general area. It seemed to be coming from the high pressure line off of the pump. I can’t picture the Teflon seal just blowing out like that, so I’m thinking possibly the pump seals have failed. Clearly something has blown out. Which seal is more likely, do pumps fail like this? I’ll probably have to get back out there and add fluid again and pay close attention to the source now that I know the general area, but just asking at this point. Pumps are quite pricey, but the pump needs to come off to even to replace the high pressure seal.

I did figure out what happened, but don’t really know why it happened. The hose connector blew apart at the pump for some reason. I have no idea if this is common, it actually seems like a poor design to me. Thinking it may have not been properly seated, I inspected it and pushed it back on (has an internal snap ring). It seemed secure, so I replaced the rubber o-ring behind it as well as the Teflon seal and put it back together. It blew apart again half way through the burping process. I had the wheels off the ground, so there was no drag on the system. I know I can buy new connectors, but I’m afraid that the line may be compromised from coming off twice. I have ordered a replacement line under warranty from Rock-auto. I’m hoping the line replacement goes well, I can’t remember how accessible the connection is on the PS rack.
