Rear differential noise

[Tnt24]

Well, my 2010 6.2L is making a pretty good whining noise coming from the rear differential. At 146,000, I cant complain since the truck hasn't really given me any problems. you guys have any suggestions where I can find all the parts needed to rebuild the rear end.

You can source a rebuild kit directly from ford, or pull it apart and get the numbers off the bearings and source them locally.

If yours sounds like this, it was over $2K to replace every bearing, new carriage, ring and pinion.
All under warranty.
Had to bring back twice to check backlash. And to be honest I still don't like the way it is.

If I had to pay out off pocket knowing what I know now I would look into a whole new rear end or upgrade.
