Ok so recently my front end started vibrating and then a squeal developed. It vibrates in 2 or 4 hi at any speed over 20mph. I removed the front drive shaft and the noise and vibration went away. I inspected the D/S and found the front u joint was going bad. Replaced both u joints and made sure to mark everything prior to disassembly and match up marking on assembly to prevent the D/S from being out of balance. The vibration is not as severe but still have the whine. Put it in 4hi and noise gets quieter under a load but comes back when I lift off the gas. As of right now I have the front drive shaft off. If I put if in 4hi there is no noise but obviously the same load is not on the front output shaft. What could it be. Bad driveshaft or transfer case. Need to figure it out fast going out of town Thursday and I'm driving my Jeep.
