Has any one had any problems with the hub assemblys on the 06 gti? I have had to replace both front hubs and a rear hub. I have after market rims on my car so its not like I can do the whole warranty deal cause of course the dealership will do anything to get out of replacing something and so this has gotten expensive since the car is so new and there are no aftermarket ones that I know of......why cant vws have studs like most other cars......
