I heard this pop and then....

ok here are a couple of pics..
one is a pic of the green axle bearings with the ring around the base. The other 2 are of each of the axle shaft splines. Looks like 1 is messed up.
Those rings at the base of the bearings sit flush on the outside out the axle shaft housing. So if I took those rings off, the axle would sit further into the splines in the differential.
