If I push down on my bullbar hard then release my car will rebound for about three or four bounces before it settles again and when I'm driving along and hit a bump I feel like it is still bouncing about twenty metres up the road. Is this a good indicator that it's time for some new suspension? The rear is the same, it is an '07 ST with 60k on the clock. It feels like it has come on all of a sudden but maybe I just haven't noticed the gradual decline.
