Did a little maintenance on the truck last night. Flushed the hydroboost/power steering. Oh my, if you guys haven’t done it, you need to. I had a mush brake pedal before but it’s rock hard now. The pump operation is slightly quieter, and steering feels about the same.
One thing I noticed when removing the return line off the hydroboost is the fitting was loose, and ever so slightly weeping fluid. I have to assume it was sucking air too, so got that fixed.
I’m guessing it was probably never flushed, because what came out was really nasty. Used a gallon of Napa fluid, and it’s still coming out a little dirty. I’ll flush again in a few hundred miles.
Same goes for brakes, trans, t case, diffs, and coolant. Most people never properly purge these fluids. PS is the only one I haven't done on my dually.
