Hi, I have a 96 cherokee country, about to roll 300,000 miles. No lift kit, all stock. I've been trying to solve my up and down vibration for 2 years now. I've replaced all u joints, wheel bearings, tie rods, stabilizer, and dampener, springs, shocks, brakes, and tires, with alignment. I still get the vibration between 25 & 30, and again between 65 & 70. I don't know what else it could be. Any help is greatly appreciated.

bent rim, driveshaft out of balance, warped rotors, front axle shaft u-joints.......a few things that may cause it you didn't replace or mention checking
