They can be stubborn if they've never been pulled before. I put a box end wrench on the ring gear bolts and put a turn on the yolk. The wrench jams against the case and the carrier will drop out. You can also use a prybar in the carrier and fulcrum against the case. Either way, I put a rag on the mating surface so I don't ding it up....Have any of you had a differential spreader and ratchet straps NOT be enough to remove the carriage from a DNA 30?
