rock krawler 3.5 lift and 2 door rubi driveline vibes....
Just installed my 3.5 inch x factor lift on my 6 soles 2 door rubicon along with the dreaded double cardian shafts. I have adjusted pinion angles and pulled the front shaft. I am getting slight vibes and harmonics at 55 and 70 mph. I am also still running my stock rubi tires and Rims until my new Rims come in and I can mount my 35s.
My rear pinion angle is a degree or so lower than the driveshaft angle to account for torque while in the gas. Could my vibes just be my tires. They have 10k on them but have only been rotated and balanced once. It vibes while in the gas but nothing when you throw it in neutral! I'm a little lost here. Any help would be great.

sounds to me like you've got rear driveline vibrations. forget trying to compensate for torque, just try setting your pinion so that it's more in line with your drive shaft.
