Just messing around tonight and stuck the axels in the housing with the posi between them to see how much play I had. There is just a little over an inch between the axels when they are all the way in the housing.
In the video you can see a little wobble in the posi when I spin it. Its really not that accurate because it is just kind of hanging there. I need to look up and see how much clearance should be between the 2 axels, I am not sure what it is suppose to be from the factory.
