I know someone on here will have the answer, because they always do. Here it goes. I have an '03 Rubicon with a 3" Rubicon Express lift, 1" body lift and a cv driveshaft, 5 speed by the way. I've developed a vibration between 25 and 40 mph(2WD) that occurs only when I am accelerating. Push in the clutch and or let off the throttle and it goes away. I'm new to this but it seems to me that it could be an allignment issue maybe due to worn out shocks or ???. I have 33's and do a lot of highway driving up to 80 mph with no real vibration above or below 25-40mph. Any help would be greatly appreciated. Thanks, Zane.
