06 rear axle issue

Not real sure where to post this, but anyone have issues with their stock e-locker rear axles?

Christmas Day, I went to back out of my driveway after just driving the truck the night before and it wouldn’t budge.. (so before when it was cold and wet outside I had the ebrake freeze up on me and once I got the truck wheels to roll it freed up of course) well I assumed same issue, put the truck in 4 wheel backed up and crack, driver side rear wheel locked up, bunch of grinding and popping. Worst sound you never wanted to hear. Needless to say something gear or axle related happened in a bad way. Got the truck turned around in 4wd dragging that wheel then it would free up and drag again. Felt like the whole rear end was coming out. Anyway tearing into it tonight or tomorrow but not sure what to expect.... maybe someone else had same issue or insight on what I may be looking at fixing..

Thanks
