Some of my problems were a clunk in the front end and no matter how many times I take it to the dealer they for some reason can't produce the same noise, could not have gone that far as they did not even put 1km on my truck. But the biggest reason is I have had a shake from day one and the dealer said they will not look at it because I do not have the factory tires. They are saying it is the tire and the tire guy is llike no way. Plus my inputseal is leaking like crazy I would emagine that is because something isn't balanced, just my guess. I think the biggest reason they will not fix my problem is becasue I didn't buy the truck from them, but what are you to do when you move to a new area. As far as the difference goes I will hopefully be able to tell you over the weekend as i am hopeing to pick it up friday night.
