Already took it in and they replaced a bunch of components (bushings, bolts, isolators). I drove a rental Dodge Caravan for the week they had it. They know it isn't fixed, said they had to order more parts and do some research into star cases for an answer. They're supposed to call me when the parts come in.
The popping is really loud, I can feel it, and I get the impression that it has to be damaging something as it continues to get worse.
For the few weeks I didn't have this problem, I fell in love with this truck. Now I'm increasingly becoming unhappy with this relationship.
