This 2008 Reg Cab. TRX 5.7 Hemi is a piece of crap. Traded my 2006 Ram in on this thing back in July and it sounds if it's going to fall a part going down the dirt road. Almost every thing in the cab rattles. The first week the battery died, it's got the Hemi Shuddering with exhaust sound vibrating in the cab...... The 2006 was a 110% better built truck.

 

sorry to hear your bad luck take it back to the dealer and tell them about it.

 

Been working on the rattling problem myself with the self adhesive installation you get at Lowes, get one rattle stopped another developes, Some of the noise is wires under the hood hitting against the fender/firewall. The servicing dealer is 60 miles away, took it last weekend for the oil change and exhaust vibration noise, they changed the oil, got it on the center console and on the drivers seat, didn't have anyone who could diagnose the exhaust vibration noise last weekend, so another trip is in order for tomorrow to try and diagnose the problem and supposedly a free truck detailing for getting oil on the center console and drivers seat. A dealer 30 miles away is going out of business over the next few days....
