I noticed when I did my last oil change on my rear axle there where junks of metal on the magnetic plug, I pull the cover. Looks like the spider gear has a few teeth damaged. Doesn't look like there is any other damage to any other gears. I've never done this before, wondering if I should give this a go? Any good threads/video's out there on a 2011 jeep jk, Dana 44 limited slip
