I have been getting vibration issues above 60mph right under me seats and it shakes the who car.
After checking everything, wheels and all, the drive shaft is the last thing I can think of.

Took the drive shaft off today to get it check for balance, before I go I took a video of me playing with the joint.
It seems like in the center of the joint it stops then goes like almost has like a dead spot, not sure if that's normal?

U joint is bad in the bottom driveshaft.....if it is giving a knocking sound when driving....

There are tiny pins in each end of U joint and when it dries out the grease inside they start to fail...

Not sure if that is a repairable....some are not replacable....

I would find a driveshaft shop that does repairs...and see what they say....

Many years ago on a GM car, I thought the U joints were non service items. Then a fried showed me that you heat the suckers and knock them out .. (epoxy like material holds the u joint by bonding inside a groove). The replacement had a expanding snap ring. This is almost about 30 yrs ago, and I do not remember details.
