I do suspect it being the hubs. If I unlock them and put some miles on it, I can count on it happening. Once I lock the hubs and drive the truck, It will not happen. I thought that maybe my hubs are locking partially, while driving, causing this vibration. If I replace the hubs with warns,then it should go away? or is it easier to replace this needle bearing?
