Thunk
Perhaps my first Cayenne issue... 04 S 57K miles w/Air Suspension
I did some searching but asking anyways...
When I decelerate from speed to a slow stop or come to a full stop sometimes I hear and feel a thunk!
Carden shaft?
Otherwise, no issues or vibrations..
Thanks!

a few thoughts
Try dropping it into neutral just before coming to a full stop.
That should isolate the driveline from the suspension and brake calipers.
If the clunk goes away and all is smooth you can concentrate on the tranny and driveline.
If the clunk persists look to the brakes or control arm bushings perhaps.
Have someone who trusts you stand next to the spot you are coming to a stop at and watch for any unusual wheel movement or hop, that may help you narrow it down.
When my "shaft" started acting up I had an intermittent squeal that sounded like a fan motor in need of oil.
Good luck, keep us posted

I get that occasionally too, but it sounds like it is in the driveline. It's not a regular occurance, just occasional.
