I have a 2000 4x4 and recently I have noticed a vibration at around 60-70 mph. Got under there and everything looks fine .... it has new lower ball joints and upper control arms. New inner and outer tie rod ends, just re balanced the wheels again and there is no up and down movement of the wheel.... I was thinking cv
joints, but have no clue how to check them.... and would they cause a vibration at high speeds ???
