Power steering leak

[A8ked]

Following JFP's advice is your best bet.
I had a mystery power steering leak/failure that turned out to be the high pressure line that had chaffed thru. The rubber grommet at one of the support brackets had popped out of the bracket and the line had been rubbing against the metal bracket instead of being supported by it. I spent an hour trying to find the leak as it was not readily visible even though the general area where the leak was located was obvious.
Snaking the original line out and getting the replacement back in took a couple more hours.
