If you have the same suspension I have then that's the problem. The lower control arm frame mounting point is to low. The upper shock mount is to low and the shock is to short. I am not sure how many of them are out there.
This is a picture of mine before the fix.
I should be done fixing mine by the end of the week. I am doing detailed instructions with pictures. Send me an e-mail and I will give you everything.
