when you push down on wing it should bounce once only and return to its settling point,if you are saying the strut is too solid to bounce then you may have a problen there,it may come down to removing the strut and spring to check them by hand,there should be a strong resistance when you try and push/pull the strut,while they are off it would be a good idea to check your top strut bearings,springs,a/roll bar links(these are bad for wearing on these)track rod ends,wear in the rack,good luck
