    Hey guys,

    lately my 8.6 proplus has been intermintenly turning left when i push the joystick right or left. pretty sure its a sticky valve just not sure which valve controls that direction... When it does do it i have to turn the blade with the truck to get it to function again.

    S1=lower
    S2=right angle
    S3=right and left angle

    nice! thanks twinman, does this sound like a pretty common failure for the ultramount pumps? ive also notice that it will drop reallllly slow when its acting up.

    Alright guys, I wrote it on a rush, been in bed for two days, sick. And forgot about the raise. Then to top it off, I took a ride last night, going down the road, couldn't understand why my plow light were shooting down a little low..Get it back home, check the mount, and what do I see.. Who ever had the truck before me never bolt on the formed support to the sides of the rail. Never bolt on the thrust arm to the cross over. Here comes the big one, rip it out the nut bar out of the frame rail.. So today my task is to fix it so I can finish out the season. So here shoot me :gunsfiring:

    S1=lower
    S2=right
    S3=RAISE/left
