I pulled my back plate on transfer on a 93 22re 5 speed truck 4x4.The worm gear had some smushed places which thats why it has chewed two plastic sensor gears.the oil gear behind it had a small place on it and looke liked it rubbed a little in the housing.Bearing has small amount of play.Will the bearing wear cause this?Cant really find anything else thats jumping out...
