New tires and balance and no vibration in 2wd so I don't think its a wheel/tire issue, and not been driving off road recently. Its really only a four wheel drive at speed issue but it definetely didn't have a vibration before the BJ lift so I'm sort of thinking it's the CV angle and at slower speeds I just can't feel it. <img src="/forums/images/graemlins/confused.gif" alt="" />
