JD 710D backhoe

The rear digging bucket will move automatically to the left or right when not operating (I would say random lol). Like if it loses all pressure and moves automatically, very slowly. Otherwise, when operating, everything is normal but if I shutdown the backhoe, it will go left or right... Would it be more the control valve or a cylinder seal/gasket or something else? thank you in advance

Check on how the hoses are connected.

When we shutdown the backhoe, after a while, if the lock pin is not installed it will move left or right (random). The hoses seems not to be the issue, any other guess? Cylinder leak? Control valve leak?
