Lost my rear wheel drive
I was backing up my 1982 CJ-5, 2 nights ago and heard a bang. I thought it was from my T-Case (Dana 300) If I don’t have my hubs locked up I’m not going any where. I’ve tried & tried no rear drive in forward or back, 2WD, 4WD, Hi or low. How bad is this??

Well I pull the T-case out Cracked it open and there it was the set screw on the fork was less than finger tight. Thus the fork would not engage the rear gear. How simple. Now to find out why my T-176 whines I 1st, 2nd, 3rd It must be a bearing?
