well I made an appointment to drop off my truck tomorrow. I asked about the vin range and they told me they would have to inspect the truck. only problem is that i need something to tow a trailer, so I called my sales guy that sold me the truck and he saved me a loaner truck to drive while mine is in there. What a nice guy huh. little does he know that I will be putting at least 200 miles a day on it and driving off road cause thats where im working. well enough about that. I was wondering, I dont have a thud when I stop or take off. the thud that I get is after I take off and after I cover about 150 feet. there is a thud coming from the front and not only can i hear it I also feel it. do yall think this part of the same problem we talking about here?
