You will normally will feel a bit of bumpiness when you turn the unit (Gears). There is a VERY small amount of movement (almost none) when you rock the antenna (minuet bearing play). You should see that the array has sealant on its underside where the antenna meets the gearbox (or it wasn't installed correctly).
