Hi

Does anyone know why the dipper arm on the back of 1986 Black Cab 3cx lowers when driving.
I've had the ram reconditioned due to a leak but it did not make any difference.

Thanks

I would think maybe one of the valve block valves is leaking or not closing completely, i had one on a New Holland that used to make the slew creep round you could hear the valve making a slight noise.
