I have loud noises either coming from the tires or from driveline only 40,000 mi on it anyone else dealt with this? Also need trans fluid recommendations is it the Dex6 or is it Dex HP? The transmission kind has a little shift flair or slide bump shift from 1st to 2nd I hope this truck isn't starting to fall apart. The noise I mentioned is crazy loud even can feel vibrations through the floor when getting up to speed is it these tires or is there some other possible issue? It comes with these off road tires any input on this I would appreciate thank you.
