I want to replace the 3.31 rear gears in my vanilla 2017 GT with 3.73s. I have a like-new GT350 rear suspension (with 3.73 gears) that I found on eBay. I have been trying to remove the half-shafts from the GT350 rear so I can remove the center section (differential). According to the service manual, the half-shafts are supposed to pop out with a bit of prying. Mine do not budge with a ton of prying. Any suggestion would be appreciated.
