Is there a video you’d recommend that demonstrates that “noise” that would mean to put some FM to the rear diff?Opened it up and cleaned everything out really well. The fluid was jet black but no major metal chunks or anything. Just some bits that looked like they were from the threads of the plugs or the diff cover bolts that fell out when I disassembled everything. Looking very closely at a paper towel with the fluid on it, it looks like a glitter bomb went off, but I think it's just clutch material. The gears all look in good shape and nothing seems to have any play.
The M220 rear takes about 1.5 qt of oil, and the Mopar additive says to use 2-5%, so I did 2.4 oz which is 5% of the 48 oz capacity. Runs fine, no noises while doing figure 8s.
