Accually its a Yukon, but anyway... I've got a '95 Yukon GT 4x4 w/ a blown 10B rear (shocking, I know). I found a set of 2500 8 lug axles. Problem #1 is I need to buy the set. Problem #2 is the Yukon has 3.73s and the 2500 has 4.10s. I hunted on here and at ORC for info on this swap and the short answer is you can't swap the 8 lug fronts onto the 6 lug trucks. What I can't find is why. Is it just a matter of brackets or is it a deal w/ different frames? I am not driving the Yuk right now anyway so down time is not an issue. So has anyone on here tried it? How about some key words to search for either here or on another site? I don't need the strength, I just think it would be cool. This thing will be a DD grocery wagon or maybe pull a trailer, but no wheeling. Just so you know my only experience w/ these trucks so far has been ripping the IFS off to put a solid in its place.
