I have always just crawled under the car and pulled the old one out manualy reinstalled the new one by lifting it up and sliding it in on my back. The new one I am installing has traction loc and is heavier than the open rear end. Plus I am 72 now and have a hernia that I am getting repaired in a month or so. Any suggestions for a jack or lift or maybe an accessory for my floor jack to remove and install these without damaging my body. Harbor Freight has a small transmission jack for around $100 that looks like it might work. This won't be my last gear change so I don't mind spending a few bucks to make this easier and safer.
