A good friend of mine is trying to figure out exactly who is right and what needs to be done to his truck as he has been told numerous things from different parties and doesn't really want the dealer pulling the cab off unless we can help assure him that it needs to be done as they will not guarantee the job will fix the sound.
'08 6.4, he is going to come and post some of his exact parameters while he was driving and can provide more detailed "driving" experience, if anyone wants to know specifics please post and we will get them posted. If I remember right this was starting uphill with his car trailer in tow.
Any ideas/insight is greatly appreciated PS.org! Many thanks ahead of time!
