I recently added a 3.5" teraflex lift and 37s to my sport s. I know I need to upgrade my axles. I have the rear LSD which I've gathered is basically a D44. Does that mean I'm ok just upgrading the front axle and then regearing and putting a locker in the rear? Or is there any benefit to upgrading the rear to an actual D44? I'm looking at getting a UD44 for the front.
