What case is the center section, 742, 489? 489 would have a piece in there, open or sure grip, but a 742 has the button as mention that will come out.
A clutch type center would fit in many different carrier housings. I have had a early clutch type in a 489 case, so that is not a guide. The OP needs to look or have sometime "in the know" look and figure out if there is something missing. We are assuming there is an adjuster on one axle. We are assuming there are still tapered bearings on the axles. We are assuming the installed axle is seated. Too many variables right now.
