Hello, my question is about the gears I want to put in my truck. I have a 2000 Ford expedition with about 25,000 miles on the motor and a 3" lift, 4.6L V8, 4X4, with 36X12.50X16.5 underneath her. The original gears are 3.55 and I think I need to go to a 4.56 to get the truck running closer to its original potential. I'm not sure what to buy or anything. I am going to muscle through the work anyways. I just wanted to know what all should I get. They sell just a ring and pinon, but do I need that or do I need a full kit, and do I have to do both the front and rear. I'm going crazy please help me out. Thanks
Unless someone else jumps in to answer I think you need to find a 4x4 forum where you could talk with other people who may have upgraded their Expeditions or Ford trucks. This forum is more for fixing vehicles, not upgrading 4x4's. Try Pirate4x4. Com. Or google 4x4 forums.
