One problem related to multiple axle suspension has been reported for the 2004 Dodge Ram 1500. The most recently reported issues are listed below.
On the highway my truck bounces so bad I have to pull out of the fast lane. While in a turn at highway speeds (65 mph) if I hit a bump my truck jumps approx. Two feet left or right. Sometimes if I hit a bump going straight on the highway it will do the same thing. Sometimes the bouncing is so bad my vision becomes blurred. I had my truck checked by Dodge two times and they say my truck is "ok" and its just "California roads". I drove my neighbors truck which is the same year 4x4 quad cab and it bounced approx. 1/4 of what mine bounces. When my kids are in the back in their car seats they bounce up and down approx. Two to three inches up and down as I drive down the highway. The area I drive in is i80 between fairfield and truckee, CA. My main concern is when my truck hits a bump and jumps out of control at 65 mph or highway speeds. I'm a san francisco police officer and I know this truck has a problem which needs to be fixed before some gets killed.
