Vehicle is mighty squeaky and has alot of bounce ,smooth bounce, but bounce..sho

Hi loosingitLynda, Yes, both can be from shocks. The shocks control bounce, and, depending how they fail, they could squeek every time you hit a bump. Even a little bump. There are numerous other items in the suspension that can squeek. The most common are sway bar links, ball joints, or control arm bushings (very common). Lastly, the chassis may need to be lubed at your next oil change. Suspension problems can be very dangerous for you and your passengers.
