I need to replace the CV Axles on my 4wd 04 silverado1500. I've seen 2 different sizes for the axle nut online, 35mm and 36mm. Before I buy the socket I need, I would like to verify. I guess I could just buy both and return the one I don't use but that's a pain in the ass I don't really need. Any help will be greatly appreciated and possible entry into my Christmas card list might just happen.
