I decided to change the oil this afternoon and while geting down underneath I noticed what appeared to be grease coming out of the side of the diff.I then decided to pull the plug on the diff and there was a mound of thick oil on the end of the threads.I rubbed it between my fingers and it felt gritty.I them put a magnet in it and out came some metal shavings,not a whole lot.The oil also seemed dark grayish.I am going to try to post a picture below.Any thoughts?
Thanks,
