Hey everyone, recently posted about a noise I started acquiring in the rear of my TJ. I think I’ve figured out the issue. See photos below, how hard of a fix is this, can I do this in my driveway? I’m pretty good mechanical wise, but is this past the scope of a Driveway DIYer? Any suggestions? All the gears in the differential are chewed to shit. Or do I bring it to a tranny/differential shop to fix? Luckily I have one down the street, literally down the street about 400 feet away. Any idea how much this might cost?
