It has most likely come loose where it is clamped on the hydra-motor. You'll need to to pull the panel with the gauges up in order to get to the clamp. There is a nut on each side that holds the metal shield on, and then behind those nuts are one more on each side to hold the clamp tight. If things are worn much, you can do like I did, take the column out, grind the slots at the bottom a little wider, and then clamp it back on.
