We'll all hafta agree to disagree on the whole CV issue. There doesn't seem to be any rhyme or reason to it: lift/no lift, Dorman, MechaTech, diff drop/or not.

Trial & error seem to be the only solution till you get to works for you. Unfortunate for me the trial consisted of 4 sets of boots, 2 sets of half shafts & a diff drop before I finally settled on something that lasts.
