Drivetrain Vibrations
I have a 1965 gto with an LS 2 with T-56 6 speed, moser 9" ford rear with 389 gears. I have baer brakes (track style) metco aluminum control arms (upper adjustable). I have a vibration around 65- 70 miles per hr. on up, never goes away. I have adjusted my pinion angle from +3 to -3. (The angles are set now at engine down 3.5 and rear pinion up 3). I keep going through rear axels bearings where the rear end grease penetrates the bearing. To stop the vibrations I have replaced the the axels, tires, rims, bearings, driveshaft, universals, center section, and housing. The t-56 tail shaft bushing is tight and there is no seal leak (8500 miles) No broken motor mounts. The frame of the car is straight (within manufactures specs).
NOW WHAT? I do not know what to do. thanks, steve fenimore
