Crazy vibration at hwy speed
Hey, did a search but haven't found the exact symptoms I have. Starting at 60mph I get a crazy vibration that feels like horribly unbalanced tires, then fades away around 75mph. Took front driveshaft off and it feels a little worse, rear u-joints don't seem to have any slop/play. I know my rear pinion bearing needs to be done but it couldn't cause vibration that bad could it?
It's not nearly as bad as death wobble but it's bad enough that I have to stay under 60. Rotated tires and it didn't changed anything either. Also, it's a bit worse under acceleration but only at those speeds.
Thx for any input!
