How do you level the Cab of the truck

I purchased a used 2000 extended cab, and the cab is .75" lower on the passenger side. Is there an adjustment to level the cab on the frame?

 

Check your cab rubber mounts on frame, is it lower compared to the bead?
If not, check rear suspenssion, you could have a broken leaf, probly master leaf and right smack in the middle @centering pin

 

I am going to check to see if either of those options solve the problem.
