I let it rest at this post, vc says shocks don't have nothing to do with keeping the rubber to the ground and I'm a joke, next his posting when the shock goes bad your wheels have less contact to the road, I think he needs to lay off the bong. Make up your mind.
Shocks do not lift your car the springs resettle, no more dribble about rebound and bounce we all know if the shock is rooted its not rebounding or absorbing the impact but still bounces up and down due to the spring but at a much faster rate.
The spring takes all the weight and energy and the strut and shock job is to absorb and damping that energy and to minimize the spring travel so your not bouncing down the road, and to give you a smooth ride on the road and help with cornering while keeping you in contact to the road surface, it also stops dipping the front end when braking and stops your tail end from dropping on take-off.
As to the wheel alignment if you haven't had it done while you had bad struts then replacing them will put it back to the correct position as before they went bad, totally up to the op if to do it or not, depends how old the tyres are.
sorry for sounding like a crack record..
