Some one was in the axle before fluid looked clean and the spindles came off with no problem. Took the spider gears out and had to take the ring gear off to get the cross shaft off. installed the locker put the ring gear on torqued to 70 ft/lbs no issues. Went to install the carrier back in the housing. Put the bearing cups on the bearings put it in the housing and what you usually do is hit the carrier/ring gear with a rubber mallet, dead blow hammer or a piece of 2x4 with a 3lb hammer. I thought I would do it a little different by placing my hand in between the ring gear and the dead blow hammer with a full swing behind it.
