I have a 95 jeep lim. grand cherokee and my frount driver side wheel shakes when i hit a bump like its going to fall off. i know my aligment is off would that be whats causing it to shake like that.

 

That could be one cause. You might want to check the lug nuts and make sure they are all tightened to spec. other things to look at;

Balance of tires
Steering stabilizer
Steering linkage bushings
Tie rods

 

check the ball joints also

 

I just came across this exact problem with my 2003 Jeep Grand Cherokee. It has a very small lift on it and larger tires. I took it to a shop in which they eventually replaced both upper control arms, both lower control arms, and a few other things I forget what they called them. None of those "fixes" fixed my Jeep, it still had a violent death wobble hitting random bumps in the road. So after all that I myself replaced the track bar, tie rod, and sway bar link and poof... problem solved! So if you are experiencing the same problems, I would try replacing the track bar, tie rod, and sway bars first. Good luck.
