Dodge Ram Drivetrain Noise?

i own a repair shop,,and i have seen the same problem before,,i got a neighbor that has one of those,,and he has a bad wheel bearing on his that was causing it to do this,,it sort of did like yours is doing,,his went out once it was in 4 wheel drive,,but came back in 2 wheel drive,,and when you,d turn it,,it sound like it was growling at you,,i pulled a bearing out,,and it was bad,,we put both of them in,,i figured the other side would go also,,but id say that may be some of your trouble with it..once you check it,,be sure and check the joints real good,,they wont act up,,unless there in a bind,,good luck i hope this help,s.

I have a 1998 Dodge Ram 1500 that is making a grinding noise (and I can feel it throughout the whole truck. I have replaced the wheel bearings, u-joints, ball joints, and the front brakes. It sounds like it is coming from the front passenger side.

A possibility is the hub bearings. Drive in slow circles to the right and if the noise goes away its possible the right side. Circles the the left could posibly the left side. You could also jack up the truck as far out on the axle ( close to the wheel and tire ) and shake it up and down and feel for movement, you might also feel it binding when you spin the tire.
