A few days ago I heard a noise in the rear differential. I got a friend to tow me home and when i took the front plate off the rear differential it was like a bomb exploded. Parts just started falling off. Doing research and trying to remove what I could with the tools and time I have, I have come to a stand still because I cannot remove the pinion gear. I don't have $1000 to send to a shop so I am trying to do most of the manual labor myself to help eliminate any shop costs/labor cost. The pinion gear will not come loose. I have used a 2lb sledge hammer and it will not budge. I have the replacement part but this gear shaft will not budge so that I can get it out of there. Any suggestions besides starting a fundraiser to get my 2012 Wrangler on the road again??
