    I bought a 2003 4x4 4cyl 2.7L with 110k miles on it back in March 2009. In the recent months, I have noticed a low rumble that cycles in a steady cadence which is very noticable at around 30mph. Clutch in or out, neutral or in gear its still there. I think it may have something to do with the front tranny because the noise disappears once I have it in 4WD.

    Any thoughts?

    Some of the ideas that I have heard is that it is not an isolated incident. When the truck is in 2 wheel drive, the front tranny has gears that turn with while the wheels turn. This gear movement slightly rubs the fronts shaft(which is disengaged during 2 wheel drive) and turns it ever so slightly causing the low rumble. The reason why it disappears in 4 wheel is because its engaged and turning all the time. Thus no rumble.

    If you go to the mechanic inform him about this possibility and see what he says. I'd be interested in what his opinion is as well.

    First, it's a diff (short for differential), not a front tranny. Second, it may be the diff bearing as it seems to be a known issue that matches your trucks symptoms.

    Mine does it too.. it's an AUTO V6 4x4. I can feel the vibration thru the floor board and the steering wheel. Almost feels like tire is rubbing however, I'm going straight at the time. Happens during both acceleration and deceleration and even with the transmission in Neutral.

    Found this thread in the 2nd Gen forum. Looks like those guys are also having this issue with their newer trucks..
