    The 06 started leaking yesterday. Can't tell what it is besides its an oily substance. Area around and under the power steering pump looks dry, nothing is on the skid plate so its coming from an area before the plate or after the plate. Brake fluid?

    Have you checked the transmission lines? Both of my vehicles are leaking at the lines.

    I'll check the lines then. There is a 10% chance I'll end up with a 3/4 ton. I miss my 8' plow and higher towing capacity. This thing bogs down towing the L3400

    Have determined it is a power steering leak. If its not, I have no clue what it is. About an inch of the shaft going into the box is wet and the box itself is wet, so it must be one of the lines going into the pump directly above it.

    Tranny lines look OK, but the Power Steering lines look a little like that.
