Vibration in Drive train

[coralcoupe1993]

Ok my vert has a vad vibration in the shifter. I thought the rear end was off because the bushings were bad. I put new upper and lower control arms. Vibration is still there. It is bad at high speeds and or rpms. Its not the damper pully. At 80 its real bad, even when I pull it out of gear and shut the motor off. Any more sugestions?

driveshaft? harmonic balancer? flywheel? check the driveshaft bolts, they come loose

if you still get it at high speed, in neutral, with the motor shut off. Means it is either back half of trans or further back. driveshaft, diff, or axles. I would first check driveshaft bolts, and give the front yoke a push up and down to see if there is any play in the output shaft of the trans while your under there. did you have the driveshaft off recently and not reallign the pinion flange to the yoke??

check DS bolts and tires still.

is it only when you let off the gas? because my vert does that at higher speeds when you let off the gas it vibrates like mad but i dont know wat it is

my old 95 did that when the gears werent aligned properly...something about the backlash being off.
