    I have a 8ft HD mm2 it is one season old, it is the two plug version I believe it is the fleet flex, the truck also works with my v plows. The plow functions fine up down left right, fluid is full etc. however when I angle the blade to the right (passenger side) and start pushing it is creeping back tward straight. I have angled it back and forth several times to work any air out of it but it is still the same. No leaks everything looks good. It is only when it is Angled right. Angled left is strong. Help please !!!!

    Those are screw type valves right? If I wanted to correct it would I turn it in or out ??? Would it be the one on the right or left ?? Thanks for the help

    Did you replace the correct one? It will be the one next to the pump relief. Possibly the check valve or ram itself. Do you have any leaks at ram or it's hose?

    I meant to post. I ended up running it to the dealer, I think they said it was the check valve and something else was outta wack, there was no charge didn't even realize there was still a warranty on it.
