Default Jeep TJ np231 output shaft

I have some vibrations and I want to put in another tailshaft to see if that will fix my problem. Anybody got one?

is the jeep lifted or stock? Do you already have a slip yoke elimator or transfer case drop installed?

Its only lifted about an inch. No SYE and no t-case drop. I used to have 4" lift and 33" mudders and it drove perfectly. I have been chasing the vibes for over a year!! I even put the t-case drop back on and it still had the problem. SUCKS

Or if anybody knows of a good place that may be able to diagnose my problem please let me know. Today I checked the rear wheel hubs and pulled a rear shaft (D44) and all seemed well. I have tried 2 different drive shafts and sets of U-joints. The only thing left I can think of is the tailshaft. Also I tightened the pinion nut down as tight as my impact would go today. It had been replaced a while ago because of an offroad incident where I broke the yoke. That incident may be related to my vibes. Thats when I started getting them I think.
