Repair procedures, guidelines for the 2004 Dodge Ram (3rd generation). In development from 1996 (styling by Cliff Wilkins finalized in 1998), the third-generation Ram was unveiled on February 7, 2001 at the 2001 Chicago Auto Show,[10] and debuted for 2002 model year on 1500 models and 2003 on 2500 and 3500 models. This was a major update including an all new frame, suspension, powertrains, interiors, and sheet metal. The crew cab models for this generation were actually Quad Cab trucks that had conventional-opening rear doors. The four-wheel-drive light trucks (1500 series) lost their live axles in favor of an independent front suspension, but the 2500 and 3500 series retained the live axles for maximum longevity and durability. This body style drew heavily from the previous generation.
