Why do my 9" carrier bearings look like this?

Oh, and BTW, this would have called banshees.

it looks like you had too much preload on the carrier bearings, you have to leave a liitle room for the differential lube to do its job. i worked for a jeep dealership for 15 years and i use to see the carriers set to tight from the factory and ruin the carrier bearings, we use to take 3to4 thousands off each side by installing different shims. on a 9 inch ford you just have to set a little less preload with the screw in adjusters.

This is a Tru-Track diff so there are no clutches. Ring and pinion look fine. Pinion bearing feels fine too.

Please disregard the stuff on the bench top. It's not fluid from the diff. Leftovers from other projects....
