Hi,
I was getting a knocking sound on full right lock, then while the dealer was recently doing a 40K service I was advised they had found the offside front hub had broken internally. I had actually forgotten to mention it to them when booking the service so was pleasantly surprised that they found the problem without being asked. I was advised not to drive in 4WD until they could get the parts in to fix it. This has now been done under warranty and no more knocking.
