Hannibal the Ram does not and never has had a vibration caused by the frame. It did have a vibration on some trucks 2003-2005 (mostly 4WD SWB) with the rear axle needing to be shimmed to increase the pinon angle. If your dealer told you this was normal then you had a POS dealer. There was a TSB issued for this wwwaaaayyyyyyy back in 2004/2005? that the dealer WOULD have been aware of along with the drive line shop. Looks like you should find some competent auto mechanics.
Andy was just asking a question. There are six body mounts on a Club/crew cab right? One set at the radiator support area, one set at the front of the cab and one set at the rear of the cab, right. Then you have the four box mounts also correct?
There is a lot more to lifting the cab then just losing a few bolts. The carpet front and rear will need to be removed to gain access to the body bolts. Note:the mid cab bolts might be accessible from out side the cab but the rear bolts are inside. I bet GM would NOT recommend doing one side as this could bend the bolts and bolt holes on the other side. The rubber mounts fit into a pocket and you need about one and half inches of clearance to get them out and back in. This is why I said $100 would not get the job done. Ford pays their mechanics 8 hours to R&R a cab but I'm sure they have short cuts.
