Help me diagnose my torsen noise (slop)
I installed a torsen diff a week ago with energy suspension diff mounts, and since then I noticed a single "clinking" noise whenever I am shifting in low gears or engaging/disengaging the clutch around town. I have only been driving it around town trying to diagnose and fix this clinking noise.
My first thought was that some of the diff mount bolts had come loose when I let the car off jack stands and needed to be re-torqued. I checked all of the mounting bolts, axle bolts, and ppf bolts and they are all torqued to spec.
Then I noticed that the torsen had quite a bit of rotational slop in it when I had the parking brake on, and I compared it to the open diff I just took out. Turns out that the torsen has about 5/16" rotational slop at the input shaft, and the open diff i took out has about 1/8" rotational slop. I took videos of both to show how significant the difference is.

Have you guys ever seen this much slop in your diff? Does it make sense that this is causing the clinking noise when its letting off and picking off this much slack in the driveline? Is this something that I can fix if I take apart the diff?
Or should I try to get my money back from the person who I bought the diff from.
