After installing lift I noticed the jeep is not level across the back. I measured and it is 3/4" lower on the passenger side, is this common? It is a 3.5" AEV lift and I have 2000 miles on it since the install. I double checked everything today and also re-torqued all the bolts. Posted this in a few forums and some say it is because the gas tank is on that side? Any advice would be welcome.
