Well I have the same situation but mine is a little more than half an inch in the rear due to a bad set of leafs that i got new just over a year ago. now i have to get a new set of springs i have about 4.5 inches of lift with 31s and when i have a a total of 4 people in the jeep the tire is just below the back passenger fender and the other one has a good 4 inches of play between the tire and fender. so i have a feeling that you might need new springs also.

 

Yep like I said earlier, mine is from the passenger main factory leaf being bad. I built my own springs using s10 springs and saw how bad that passenger side was and am kicking my self now for not taking care of it when I had it all torn down. Oh well, more play time with new air tools
