cause mine got no play when the rear diff is in as well.
Yeah, that with the diff removed.
I did a lot of testing with the drivetrain because I installed Aluminum Driveshafts and ceramic bearings. So I was very carefull about checking for play. I tested the drive train (both diffs, both inputshafts ) and checked for play on each seperatley.
What I found out was that if you are using the delrin outdrives, to make sure you use 1 copper and 1 silver shim. 2 silver shims made my diff not spin as free. The Rear input shaft needs to be as snug as possible, but as smooth as possible. I used the stock 3 shims. Also, make sure the shims are positioned on the side closest to the spur gear, otherwise you get play.
