Hey all, I have an m4700 that has a leak from the collar (I believe) of the power steering hydraulic line. See attached pics. My problem is this line disappears behind my dash. I have removed a lot of the dash/shroud and I’m not anywhere close to the other end of the line. I can reach in there and feel where it seats with my hand but no where close to getting to it. No idea what it would take to even find the other end?m. Any input on removal/where to start?

No removal. Disconnect at each end and renew orings. WSM is your friend.

Hey Dan, perhaps I wasn’t clear in the first post. There aren’t any oring issues. This is a metal line with a pinhole rust leak around the collar.
Also the disconnect at each end part is what I’m asking about. I’d like to take the line out but cannot get to the other end of the line routed up behind the dash

The line is connected to the inlet port on the steering controller. Take stuff off until you can access it. The WSM should have pictures and a more specific list of the "stuff" . The line is roughly 12" long but its probably more than a little work.

Thank you Dan! I just googled and realized WSM meant workshop repair manual so I’m going to purchase an E copy and start digging to see if it has any input. The part where it connects to the steering controller is the issue for sure. Almost looks like the gas tank will have to come out. There’s just zero room back there. Thank you for your help.

JFYI the tube is cinnected with a compression nut and sleeve.
