So I'm taking out the Commando for its first real Cruise, things seem to be running smoothly (other than the fact that when I finally put its new license plate on I noticed that somebody had taken my gas cap shift knobs and all the gas from my tank)so I pull onto the highway. Next thing I know I hear kind of a bang Jeep starts skipping and skidding to a grinding halt I managed to get over into the shoulder. Look behind me expecting to see my entire Drive Line in pieces on the highway because that's what it felt like but no parts to be found everything's under the Jeep where it's supposed to be. So I shift through the gears to see if they're all still there and they are. Pierced to check my transfer case levers and they seem to be in the correct position. So I try and go forward and the Jeep is stuttering and having trouble moving. Tow truck driver shows up trying to tow me and he tries to pull the Jeep and it is just dragging, rear wheels are locked up. So he gets his fancy do hickeys and whatnots and lift the rear wheels and tows me back to the hotel. So I do some old-fashioned Googling and youtubing I open up my rear differential and you know what I found...... nothing. zero oil perhaps an ounce and a half to 2 oz total. So I guess that's more like what I didn't find on the flip side of that what I did find was some little pieces of metal from a broken tooth from The Ring. So I lifted up the rear end and the tires spin freely each in opposite directions so that seemed good. So I figure I need a new ring and pinion @$179 that seems fair no big deal until I looked up what it takes to install one and it seems rather extensive with special gauges measuring backlash and depth of the opinion among other things for these specialty toolsnot to mention I'm a novice @best . The time and space isn't available to me at the moment so I'm curious do any of you know which axles I could pull off of another vehicle in a junkyard that would be a direct bolt-on replacement of course there are no Commandos in the local junkyard. Any help you can give me would be great I really need to get this thing back on the road ASAP because it was supposed to be a working project as my daily driver and weekend fun time wrencher and right now all it's doing is stressing my wife out and earning me the dreaded i told you so scowl from my wife. Anyway switching out the rear end seems faster and cheaper for the tone being.
