Driveline vibration!!! I need help!

850moparkid:
cant switch front to back small wheel bolt pattern on front but the wheels are new when i put the new wheels on the vibration was still there
oldmanmopar: when i initially inspected the rear end (b4 i noticed the vibration) the pinion was leaking...replaced pinion seal and 1axle seal differential was inspected(visually) and nothing seemed out of the ordinary ...when i lengthned the drive shaft the driveshaft company replaced u jounts and asked me to make sure the u joint snapped into place with no "gaps" around u joint and yoke mating surfaces
rob robinson87: these tires have been to 2 different places to be balanced....when i bought them and again when i bought the new wheels...but i will take it to a place where they can check the tires/wheels dynamically for an imbalance condition
