    Not sure if chattering is the right word. I run 2008 8'6" xblade straight blade on f350. Plow runs great overall. Angling left or right no issue. When lifting or going up it chatters at like the last 4 or 5" of lift. No huge noise but you feel some cavitation. Checked fluid, checked and cleaned cartridges, cleaned connection plugs added new dialectic, lift chain all in good shape. Any thoughts??I'm not mechanically inclined enough to pull the pump apart but if that is the issue I would take it to a pro. Suggestions appreciated boys!!!!!

    if the lift cylinder compresses as it should then yea good chance its the pump it should be at minimum 1750 psi IF u have a gauge u can un screw the lift cylinder hose where it goes into the cylinder and put the gauge on there OR take it to the fisher dealer and they can do it for u in 10-15 minutes
