My 2004 Titan LE King Cab 4x4 with Off Road Package and Big Tow Package has developed a terrible vibration or wobble in the 40-45 mph range. It started after I hit about 105K miles and seems to be getting worse. I now have 129K miles and I have already tried replacing the U-Joints on the front propeller shaft which had no effect whatsoever.
Has anyone else had this happen to their Titan and is there a known fix. I could try replacing the front differential/carrier but it is a pretty expensive part to buy just to experiment.
Any ideas to resolve this would be appreciated. Shims, driveline balancing??
