I have a Touereg and will soon be towing my Cup Car with it. I've heard they have the same problem. I see Vertex has a replacement bearing support advertised to install in just 30 minutes... not sure its worth the high price since from what I understand its the rubber support that fails due to the center bearing binding and overheating. Does this sound correct?
Seems the new support may be of little use without a reliable rubber bush and bearing...
