Never in my life have I experienced anything as miserable or difficult as trying to remove my power steering return line. I can move it around the nozzle pretty easily but for the life of me, cannot make any progression on moving it down the nipple, despite using WD40, sticking screwdrivers and small tools down the line and then spraying, using a wrench to twist it, etc. There is no way it is coming off. I spent probably $100 buying the tools for a PS flush to do this on my own but I am pretty sure I'm going to need to take it to a mechanic and pay $180 for a flush.
As a last ditch effort, how difficult is it to remove the return line from whatever it connects to at the bottom, so I can just cut it at the top and replace the entire line? Or, will the flush be just as efficient as continually topping it off with new ATF, driving it a bit, and then extracting all the fluid from the reservoir and refilling a few times to cycle all the old fluid out? I have a gallon of ATF so I can fill it up multiple times. Really bummed I couldn't finish this job the correct way.
