Driveshaft diagnosis help

[Joyaant911]

So after much time with this dreaded vibration seems like my mechanic is leaning towards the rear driveshaft U joint as I already replaced the flex joint and bearing with no luck.. Does anybody have any experience replacing a rear driveshaft u joint?

Do you qualify for the driveshaft recall? Does that apply to you?

There was a driveshaft recall?? Looking into this now

[mitch808]

Sorry, just looked at your profile, you have a 2007 no? It applied to newer models, 2010 ish.

Does anybody have experience with failing driveshafts?? Does the driveshaft have 2 flex joint bushings? One rear one front? If I accelerate rapidly the entire cabin center console viciously shakes and vibrates like something is broken or loose in the driveshaft. Before I start tearing it down I wanna be ready with all the parts I'll need to rebuild under there

Can you pls kindly keep us posted? after paying the diagnostic fee with my dealership, they said that it is normal play with the yoke @ transfer case and that another X6 did the same too...

I dont have much vibration other than slight at the 60~65mph mark, so not sure how to look at this now.

I talked earlier with the mecanics and they said they removed the drive shaft and looked inside of the transfer case. That female conection( input shaft,yoke) it is damaged. Cobra transmision sells parts for the transfer case but I will replace it with a reman. Does anyone knows if above this u-joint is a drainage tube from ac or windshield? Thx

At any dealer they have reman for about 2200$. Good luck to you too.

Is the part inside the transfer case replaceable I'm seeing the same play in my front shaft I think that's my problem.. Also my flex joint which I just replaced is torn to shreds.
