Bleeding Power Assist Steering

Hi all!

I'm going to be replacing the power assist ram (bendix) on my 77 f250 as it is leaking. I don't imagine this will be too difficult, but I'm unsure as to the proper way to bleed the system.

I've searched the forums and I now know way more than I did about the system overall, but no idea how to properly bleed it.

I think the previous owner had not used the right fluid. I'd love to bleed in all new fluid if possible. Type F atf according tho this thread:

Is it just a matter of replacing the ram, then jacking up the front end and cycling left/right a few times? Any help from your experience is very much appreciated!

Thanks!

That's pretty much it, though it will probably be more like 60-80 times, there's a lot of hose/line to bleed all the air from, remember to use type F

<Montana is not wrong, but 100 times is a little excessive. Those arriated bubbles can be a bitch.

Just drive it or let it sit overnight after cycling it a few times will work.
