Just noted this last night. At low speeds, like 0-15 MPH, I am getting a squeak from under the truck. Too fast to be a brake dragging or something around the wheels. I lubed up the rear DS (had done this recently, maybe a year ago, less than 3k miles.) The front Drive shaft, I got to the rear U joint before running out of grease at 10pm last night. Seems almost more like rubber squeaking. I did drive it through a DEEP puddle a few weeks ago (about 2 inches of water coming in the doors), but I didn't notice it until last night. Was driving 85 for about 5 minutes last night. Where should I look and how to I ID the part in question? I tried rocking it back and forth in park, and I couldn't replicate the sound from under the truck.
