Hi guys, I'm new to this forum and I was going to see if anyone could tell me how to check and see what gears I have in my rear end. I bought a used 2011 5.0. I'm really starting to get into adding after market parts but the guys I bought the car from added quite a few before me. One being 4.10 gears but he wasn't exactly 100% honest about everything is there any easy way to tell if I have 4.10 gears or not?
