So I took a trip with a friend up to Scottsdale. One way it's about 150 miles from my house. Well, we get up there and we hit a little traffic. Stop and go for about 5 miles and I notice a sound coming from (I think) underneath the drivers floor board. The noise is most noticeable when decelerating from 30 mph or less, coming to a stop. The noise is "in time" with the rotation of the tires. Kind of like a ruh, ruh, ruh, ruh noise, if that makes any sense. The first thing I thought was wheel bearings, so I jacked the front end up and tried to move the wheels from 12-6. Neither wheel moved at all. I get under the truck and notice a little bit of leaking around both CV flanges (where it meets the differential). Also, I did see some oil around the back end of the differential, where it meets the half shaft, but I think that's from changing the oil a few weeks ago. Are the next things to check: u joints and maybe pinion bearing on the diff? I really hope it's not the pinion, but I want it fixed. I may just replace all of the u joints anyway. Any other ideas would be appreciated.
