I am in the process of replacing the power steering hose (leaking from the top near the crimps), but the new hose flare nut won't tighten all the way down. I get almost all the way there, and then it stops and I can't tighten it anymore. There's about 2 threads left on it, but it won't budge. I made sure I didn't cross thread it, so I can't see why it won't go in all the way. Anyone have suggestions or anything? I'm getting really frustrated, which is making it harder for me to work. Plus it's about 30 degrees so that doesn't help. Thanks guys!
