    I just got my unimount plow setup on my truck. When the plow is lifted, you can take the blade and it will move side to side a little. You can see each of the side adjustment cylinders oving in and out a couple inches. If you jerk the wheel whole driving, it will move a little side to side. Is ot supose to do this or do I have a problem? I just changed the fluid today, and im not sure, but I dobt remember it oving side to side as uch before. Could I maybe have air in the lines?

    Will this effect anything when i plowing? We ight get soe snow here this week and I want to be totally ready for it, so any help is appreciated,

    If you grab the plow and pull back on it will it move all the way from left to right?
    - Check the crossover o rings and the all check valve o-rings

    Or are you talking about if you push down on the top, the plow wobbles up and down?
    -That just happens with unimounts, the center front bushing gets worn and ovals out. I wouldn't worry to much till it gets really bad. Mine has held on this long and it is bad.

    Hope that helps

    If you grab it and pul back it moves let to right just a few inches. The cylinders move in and out.

    Since you changes the fluid, did you purge the air out like Western says to do? If not you may want to try that first.

    Yes, I did purge it a couple times. I used dextron 3 tranny fluid, could that have anything to do with it?

    No ATF fluid is fine.

    Sounds like the crossover relief valve. This valve has two o-rings on it. Pull the valve and check to see if either one is damaged.

    Here is where you find it.

    If it will hold the set angle with a snow load against it even though you can move it slightly by hand, then it still has a little air in it. Not a big deal though..should work it out on it's own.

    If it won't hold the angle, then go after the cross over valves.

    Ok, BigT, B&B is back.... listen to him, he knows his way around this stuff.


    Where have you been? I been trying to fend off all these questions on my own.

    It's like a full time job! -Good to see you back on!

    No ATF is not fine. Slower operation more wear and tear on everything, higher amp draw.

    Not related to the other problems, just FYI.
