I have a 2004 Nissan Titan 4x4 XE. It has a 2008 rear end from a pro 4x with the E locker. When i lock in the 4wd it seems to be dragging the rear tires, almost like the gear ratios are different Has anyone had this problem or know if the gear ratios are different in the 2004 xe models and the 2008 pro 4x? I did not do the rear end swap so thats why i am confused on the issue. Any input would be much appreciated. Thank you.
