Almost since day one I have had a Drive line vibration issue. last year the drive shaft along with the ring and pinion were replaced. The vibration came up thru the center tunnel and vibrated the whole center console.

The vibration came back 6 months later so after having my car in the shop for three weeks, they replaced the entire rear differential, case and all to include the pinion flange, Road Force balanced all tires.

My car is now the smoothest it has ever been.

Finally!
