Anybody know what size the lug nuts are for a GM 1/2 ton 4wd pickup,, I have to find out everything I have is to big or to small ,,,,,,and that lug wrench supplyed with the truck SUCKS
They should be either 3/4", 13/16" or maybe 7/8" if it's got the heavy duty axles. 3/4" crosses to 19mm if you're using metric sockets. Those were the most common truck lugs I saw at the shop.
Guess I forgot but I just checked and 22mm crosses to 7/8ths. You oughta be able to eyeball it with a tape measure now that you've got a range of choices.
