Hey guys - working on a gen 1 hot rod equipped with new Moser 8.8, w. zero miles. I pulled the axles out to swap some brake components and while looking at things inside the diff I noticed that the spider gears seemed to be really loose on the cross pin. When you rock the pinion back and forth the spider gears wobble quite a bit. I called the Moser tech line and the guy just seemed to want to tell me how to measure the back lash (ring and pinion). He finally said he didn't have a spec for the spider gears and didn't seem to be concerned with it. I did make some rough measurements and came up with about .010 clearance between the id of the gears and the diam of the shaft (cross pin). .010 may not seem like a lot but on a 1 inch diam shaft that seems huge to me.
I don't have that much experience messing around inside rear ends (no pun intended) but was wondering if anybody has ever noticed that before.
