I have a 1990 XJ with 8 inches of lift, i have installed a slip yoke eliminator. I have it on Mickey Thompson Baja Claws. When i drive down the road it's so noisey that I can't hardly stand it. I also have some vibration, that is bugging the crap out of me. I am new to the world of lifts, I would like to beable to drive down the road in with out having to wear ear plugs.

Could some one give me some ideas on what it could be, should I lower the transfer case 1 inch, could it the the tires? Or wheel berings in the front end. I need help!
