I just install some 1.5 blocks in the rear of my 04 Titan. Here is my deal. I can not find the problem. The axle is crooked by 3/4 of a inch. I checked ever thing I can think of. Both the pins are lined up. The driver side is farther back then the passenger side. I have 295/70/18 on it and I just fit a finger between the tire and the mud flap on the driver side. Why? Why? Why?
