Ok, so we have a noise seemingly coming the transmission/T-case area at hwy speed that only happens under power. Correct? Now, What does it sound like? (Like bad U-joints is not decriptive enough for me!)What type of noise is it? What about frequency? Remember the driveshaft is turning at engine RPM any U joint noise or vibration will be at a high freq. 2000 rpm is 33 1/3 turns per second. More clues please! <img src="/forums/images/graemlins/confused.gif" alt="" />
