I have some serious driveline vibs on my '97 ZJ... only asking for help because I have no idea what else to look for... heres how it goes.
I am stuck here.. I have no idea what else to look at. With the front driveshaft removed, I still get vibs at high RPMs, or when I reach 80mph.
What else could it possibly be? Tweaked unibody? Tweaked tranny output shaft? I am lost.

- Installed Teraflex S3Z (3.5") suspension, lower adjustable arms front and back, that is when the vibrations started.
- Rebuilt the rear end (for something else), still have vibrations.
- Removed front driveshaft, balanced and installed new-ujoints on the rear driveshaft, still have vibrations.
- Replaced motor mounts, and tranny mount, still have vibrations.
- Install 1.25" coil spacers, still have vibrations.
- Install SYE, CV driveshaft, and upper adjustable arms... vibrations get a little better.
- Replace pinion yoke, vibrations still there.
- Replace CV driveshaft, doesn't help.
- Replace tcase output shaft, vibrations get a little better.
- Measure for runout, looks good.
