Thanks Barnbird for all the great advice! I had no idea about the axle bearings not being lubed by the gear oil. Glad you said that.

So I need a sealed bearing then I assume?

Does the axle four bolt flange have seals as well?

If I find the bearing race was spun as you mentioned then is the axle toast? ( I always get the worst cases and uncommon situations)
Or is there a repair type bearing?

I was really glad to see I have my first bolt in axles. I have actually had my c clip axle come out when driving (not fun)

Since one axle bearing is toast I assume I should just do both with their seals?

Also do the carrier bearings get sloppy? If I have fluid when I remove the cover and no obvious damage is it safe to assume all is well in there?
