My sister-n-law has a '99 Mustang/3.8L/auto. She's been having some noise coming from the rearend as of late. I drove it myself, and it's a constant, almost "grinding" noise. The fluid level is good in the diff, but I was wondering if any of y'all have any experience with these. Could it be a bearing or something?
 
Open the diff and check the carrier bearings for play. I believe its got the 28-spline 8.8. When I picked my 31-spline 8.8 up from an 01 Mountaineer, it needed new carrier bearings and only had around 40K miles on it. Must be a common problem with these axles.
