99, 4.0, 5 speed, Just Installed a OME 2.5 hybrid kit, new control arms upper and lower and I have vibrations. It feels like I am driving over rumble strips when I accelerate quickly- also sounds like I have a new set of mudders on it. I notice a little noise/ vibration but not alot from 0-40. but the harder I get on it, it happens. I have been told a Slip yolk and a CV driveshaft would fix it but since it's a small lift would a transfer case drop work instead? Tires are 235/75/ r-15. They have been aligned and rotated. and the tread is at half. Opinions? Thanks-
