Vibration nightmare Help!
Ok new here and I need some input,
84 Z28 t5 305ci
at about 75 I hear a rumbling vibration start, it is a constant vibration in the rear that I can feel everywhere especially in the shifter. ThE faster I go the worse it gets,till abou 90 then it stays the same, it doesnt matter if I take it out of gear its constantuntil the vehicle slows below 75.
ive balanced tires, replaced rear drums and replaced front bearings. I lifted in up in the air at my shop and the drive shaft doesnt seem to shake but I dont know. Ifeels like somthing is goi g to blow apart!
Ideas?
