At 40+ mph speeds and drive over a bump in the road the rear feels like jello... on 2009 Hyundai Santa Fe

I have brand new tires and just changed the rear shocks. Mechanic states everything looks OK ... but I when I drive at highway speeds and hit a bump the rear bounces like jello. I hit a series of bumps I have to slow down
