Need Real Help 2012 Panamera Turbo S
I hope someone can help me before I go broke or retire the car for life...
2012 Panamera Turbo S.
Car have not been abused in any way Serviced properly always.. Issue is as follows. Car starts Vibrating and it vibrates hard at certain speeds. So I had the entire cars checked and found out Transmission Mounts are Shredded. Changed them. Still shaking. Air Suspensions gave up at same time so Changed both Air Suspensions. Still Shaking. Then found out Drive Shaft had an issue opened up and found out one little bearing was shredded in spots and was about to give up so spent $ 2,400 Changed the whole driveshaft since they don’t sell only bearing. Still Shaking. Three differnt mechanics said control arms and went ahead Changed the lower control arms. Bushings were gone which is common. 3rd time for lower control arms. Then they said wheels are too big and I took the 22 s out and installed a set of Brand New 21s with brand new pirelli p zero Nero gt s . Still Shaking .
What else do I need to do before I sell the car as parts. 75000 miles and all highway miles driving between two cities every other day with cruise. Not racing not abusing etc. ANY IDEAS????

Wow, you exhausted just about everything I could think of. Other than the engine mounts that areolithe suggested, the only things left are the bearings or maybe some pistons slapping.
Are you the original owner?

Clarify terms
Engine mounts would show while stopped, so if the vibration is only when moving, it's not engine mounts. It does sound like a faulty wheel bearing or a bent wheel carrier. One of mine is bent and I can't perfectly align the car. They get bent when someone hits a curb too hard. A competent dealer should be able to figure out which it is, especially if you can nail down the side.

Appreciate the response rbrunelle, but can you clarify what you are calling the "wheel carrier"? It seems from Gaudin Porsche drawings that the term "knuckle" describes the large aluminum part that holds the wheel bearing (I commonly call that the spindle), and they use the term "hub" to describe the part that mounts through the inside diameter of the wheel bearing and that the wheel studs screw into. The axle half shaft passes though the hub. Thank you.
Did you solve the problem?
thanks in advance for answer.
