Hey I have a rearend out of my truck with a set of 4.88’s with only 150 miles on them same with the posi carrier. The gears made noise when I let off the gas and couldn’t get anyone to re set-up the gears so I swapped a used 4.10 take out differential in. I have the brakes, brake lines, axles etc to make it complete, those parts have around 30k miles. Details in my craigslist ad, I’m located in Massachusetts. https://southcoast.craigslist.org/pts/d/berkley-dodge-ram-srt-10-differential/6929581524.html
