Hello dodge lovers, I am looking for anyone who can tell me what could be making a pulsing growl sound under my 2006 charger above 40mph.It subsides under 40mph. I just purchased it from a used car dealer and I do have a 60 day warranty with it. The car is an SXT w/V6 HO w/67k miles. It runs fine, shifts fine. The dealer already installed one front wheel bearing Assy before I took delivery. I'm not so sure its the other wheel bearing because to my knowledge (correct me if I'm wrong) a bad wheel bearing usually makes a consistent whine sound that increases and decreases with speed. There is no shimmy,vibrations or tracking issues. Possible tranny or rear end issue??? I would like to provide the dealer with some info from you guys. The dealer knows about the sound. Any information you can provide will be greatly appreciated. Thanks chargemeup 72

 

For your info, it was the left front wheel bearing assy. Replaced it, noise gone.
