u still running factory front end? if so there is a screen on top of the front pump. i used a cutting tourch to cut a hole in the cover-frame that the front pump bolts to and remove the hex plug (1 1/8 socket i beleive, been a few years since i cleaned mine!! lol) with a screen under it and clean it. it will have metal from the brakes in it. that part of pump does not pull filtered oil from main filter system and it is used for steering and brakes only. . u can see hex plug from drivers side by radiator and fuel tank but u cant get to it and remove it unless u take front pump out or u cut a hole on top of the plate!! there is 2 hex plugs there but only one will have a screen and i beleive if i remember rite it is the more on top?
hope this will helps, it did in my 4010

your supply pump stops turning when you push your clutch in,if your acculumlater is gone maybe your losing to much pressure.

Did you remove your Hitch and SCV's? Did you just cap off the supply line for the Hitch and SCV's?
