I just purchased a 2004 Ram 2500 Reg Cab Long Bed SLT 4x4 Hemi 35k miles for $13,800 certified. Was this a good deal? It has a weird noise when accelerating that the dealer said was a common problem with the exhaust on this year truck. Is this normal or has anyone heard of it? Also I here a constant clicking every few secs. from the engine? The rear on the drivers side is a little wet on the outside of the pumpkin, dealer says its not diff. fluid but its grease that has seaped out from the factory and that its normal? What kind of gas mileage should I get with this truck? Any other problems should I look for with this truck? Thanks
