    So we have this older unimount and it is locking up on full left turn. We can angle part of the way left and it will run back straight and angle right full but wont angle full left without locking up.
    When it does lock up we can remove the hose and coupler on the right side ram and get a small spurt fluid, and the plow will angle back until we angle full left again.

    we checked the s2, s3, s4 valves and they all work with a solonoid bench test. (thanks for the search function)...

    We replaced the popit check valves and no change.

    Hate to keep throwing money at it. Any ideas? sure would appreciate it. thanks

    Or better yet ditch the couplers altogether. A Uni shouldn't have them anyway, why add components you don't need that will fail eventually?
