Alright, you've been building, wheeling, buying for, and modifying your truck long enough to have learned a few things that are factual about the world of truck ownership and the off-road lifestyle. Well, factual at least in your world. You might know, despite what everyone else claims will be a direct swap, that that junkyard GM axle isn't going to bolt right in without a lot of welding, cutting, and pleading. You just know this for sure. It might be that every time you go wheeling, you have to pack every bit of extraction gear you own because you'll get stuck. Happens every time. You just know this for sure.
We'd like to know what you know for sure. Tell us, and we'll compile the best of 'em in a story you'll find only here at fourwheeler.com.
