Driveline vibration, help - Ford Forums

MattP51 · 07-16-2007, 20:04

I have a cyclical vibration somewhere in the driveline at speeds above 85.

This is what I have done to solve:
New axels
rear ujoint straps torqued properly
new pumpkin
new transmission
motor rebuild
car is at proper ride heigth
different driveshaft (although I did not have the new used unit balanced)

I have heard of other classic Mustangs have this same prob but I never heard of anyone solve it.

Please give me some input, thanks.

You have done a bit already. Are you sure its drivetrain or could it be your wheels/tyres.

Can you explain the vibration a little. I'm not sure what more to add as you have replaced a lot of the bits already that are likely causes.
