Is it the death wobble (shaking violently when you hit a pothole/bump in the road, almost out of control)? Does it occur when accelerating, braking, coasting, overrun? If you increase the speed does it go away?
replaced the shocks
Replaced worn ball joints
may be worth checking your u-joints, steering stabilizer, it is the shock that runs side to side near the front lower of the engine, if this is bad it will cause some violent shaking
