Just wondering how much I should be able to rotate the driveshaft on my truck when it is parked in my driveway. I have a 2012 f350, tuned and deleted, with the readylift stage 3 leveling kit which raises the rear one inch. The yoke coming out of the t-case has come out about 2 inches. I am able to rotate my driveshaft a bit and it has some up and down play coming out of the t-case. I beleive this could be the reason I am getting a pretty good lag at takeoff. Sorry for the long post, just looking for some insight.
