bad vibration After installing my 9 inch. umi torque arm setup, and panhard bar. I'm now getting a bad vibration at 60+mph. I think it could be my pinion angle, but it doesn't appear to be off that bad. 
You need to make sure all the angles are correct. Make sure the rear is completely centered, pinion angle is adjusted properly and if you have adjustable LCAs make sure the rear isn't crooked because of those.
After installing my 9" I had horrible vibrations, I mean to the point I didn't even want to drive my car. After correctly adjusting the pinion angle a large part of it went away. In the end it took a new driveshaft to cure it.
