Just had a wierd experience on the way home from work. When i let of the accelerator i got some serious shaking through the wheel and when i accelerated again it calmed right down. But returned worse once i backed off again. Did this for about 500 yards or so, then stopped.. I understand i might have a bush that is worn on the front as i have the occasional click. Do you think this could be it? It felt more like the wheel was going to fall off. CV joint maybe?
