That's funny stuff, right there!The remedy is to get rid of the torsen diff and upgrade to a tru trak when they make one for the super 8.8 if they haven't already!
The Torsen units actually have pretty tight backlash for the type of differential - being helical gear, without preload springs to mask the differential gearing lash.
When you check lash like shown in the video, you're checking system lash. That is, you're picking up everything that contributes out to the hubs, including all spline joints. On cars with the Torsen, its worth repeating that the 3.73:1 gear ratio multiplies system lash more than lower numeric ratios do, so the same level of lash in the axle components will feel worse. It would measure about 12.5% more than with a 3.31 ratio.
It was pointed out above that the ring and pinion lash is set somewhat high on these from the factory. There are also 4 spline joints on each CV shaft, though I know that the end that goes into the diff tends to be fairly tight. My point is that you should keep in mind that there are lot of factors involved here. With that said, Ford tends to allow a looser set up then, say GM does. Compared to another similar project that I worked on, they (Ford) probably has at least 50% greater lash in the axle as a system...:(
