02 4.0 Front Propeller Shaft

[Apexmaster]

hey guys i can feel a vibration coming from under my driver seat, it gets stronger as i accelerate. how Can I identify it is the front propeller shaft. the one going from transmission to transfer case, or could it be front left axle? i peeked under and dont see and obvious bent on it. are there any bushing which go bad?

No answers in 2 days? That's because it isn't easy to find the vibration spot. My left rear CV shaft was so bad that it made the gas pedal vibrate at 45 MPH. I worked my way through the 170,000 mile beast for a week and found the right front wheel bearing was the second worst part under there...but no propeller shafts and no U-joints were bad. Hub bearings go first, then CV shafts.

The prop shaft goes between the transfer case to the front axle, not transfer case and transmission. Just pull it off to rule it out.
