If you move the arm there is almost 2" of vertical free play (no resistance felt - move it easily with little finger) then past the 2" it feels like it should (hard to move) but if you stop moving it then there is still 2" of free play but it's moved up! So, basically if you are driving along and the suspension travel is 2" or less then it feel like you have no damper that side, but if the movement is over 2" it starts to damp. Very odd.
Also, there was around 1/2 to 3/4 of an inch front to back movement! which obviously is a sign that the thing is knackered!

No wonder the wheel was vibrating and bouncing over 60 MPH!!!
