the bearings are freed up and thay are on the outside of the dif case... thay spin by finger when i screw the case closed yea... ok the two things that come out of the center diff that the drive shafts go into is what is what i am talking about something is binding up the gears inside the diff.... not the diff itself on the brackets on the car... from what i can tell nothing looks damaged or broken i looked over ever tooth on every gear inside the damn thing....
