I have an 86 K5 lifted 8" with 36 Baja Claws. Just bought it a month ago and its been sitting in the driveway. Not really driveable because its leaking oil and Im recovering from medical probs and cant work on it or afford to get it fixed. In the meantime been searching for axles with better gears to swap in, it has 3.08 and is a DOG. Its hard to find axles locally for a good price, I keep searching here but not having luck finding deals I can afford or jumping on them quick enough. Back near my parents in Pittsburgh found an old timer with a 82 3/4 Suburban. He says its a 14sf rear with 4.10 and an Eaton locker, does that sound correct? He swapped in a front end from a 74-75 pick up he said that has "Big Hubs", "really big hubs that stick out and have 2 pieces to them compared to stock hubs"....what the heck does that mean? Is it a good thing or bad thing? The Suburban is Diesel and has 150k miles on it. Selling the entire rust bucket for $800. Would it be worth buying for the axles, and would axles with 150k miles on them still be reliable, no idea how many miles on the front axle since it was swapped in from an older truck. Thanks!
