it's proven that the crush sleeve moves on high torque applications, once it moves your bearing preload changes as well as your pinion depth which effects your ring backlash.
ask your gear manufacturer of choice for a solid pinion spacer or a crush sleeve eliminator for your diff. they are common items.
