I have a 2000 ford ranger 4x4 with a 3 inch body lift and 4:11 gear ratio swapped for my big tires… Which are 33x12.50 mud claws. Anyways, at low speeds, it is kind of an annoying vibration around my feet area. When I get over 45mph, it gets scary as hell. The vibration turns to a shaking of the entire truck. Now, it still handles perfect, and I checked the U joints and they were fine. I checked front and rear diff fluid and it was fine. I didn't see any leaks. I checked wheel bearings and they were good. I checked the CV axles for any torn boots or play and they seemed fine. I even jacked it up and spun the tires in drive with it running, and no noise. I am lost… Maybe it's just the tires? They are very aggressive mud treads. Maybe they aren't balanced or I slung the weights off or something. I don't know. The only thing I noticed is a little more play in the rearend than I would like. I can turn the driveline a quarter turn in both directions in nuetral and wheels on the ground. Any ideas, advise, things to check next, or anything would be appreciated. Thanks in advance!
