I have the carrier out on the bench ring gear off and am trying to drive out the lock pin from the spider shaft. It won't budge. I am inserting the punch from the bolt side of the ring gear flange like the manual shows. It's been ten years since I did this operation last but it wasn't that difficult. Is there anything I'm missing??? Any tricks??? This is on a different jeep than before. It looks like May have never been apart before. Did they somehow stake the pin at factory or something. I'm afraid to go any harder. A 3lb sledge and pin punch should have done it right??? Should I try heat or something?
