| Pulsing/Beating vibration over 70mph....cant figure it out?? | I have this vibration that pulses about1-2 times a second going over 70mph. It shakes the whole car and seems to be comming from the rear. I had the wheels and tires balanced as well as the driveshaft balance checked with no change. I then had a new drive shaft made and they reused the old yoke had new u-joints installed and the whole thing was balanced....the vibration is still there. Any help??? | | |
