So im on my way too work this morning and all of a sudden a SERVICE STABILITRAC flashes on the DIC. So i take it in to the dealer for them to look at it. At the same time i told them about a vibration i was feeling. The first time i brought the truck in three weeks ago, three of the wheels weren't balanced at all. So, i got a call from the later in the day that they do feel a small vibration but according to the service writer "it's within spec". Can that be or could this be a problem? should i keep pursing this ?
