I just had a Tonneau cover added to my truck....No more bounces on the freeway...works great, thanks for the info....

 

I know this is an old thread but this vibration problem has not gone away. I just bought a used '03 Ram 1500 QC SLT with 30K miles. Recently I have been experiencing the vibration issue when driving between 65-75 mph. The truck did not do this at first and I began to worry that I bought a ruined truck so I decided to do some research and that's how I came to know this forum. I was relieved to see that it wasn't just my truck that was doing this. And after reading the captain's post it all makes sense now.

I bought the truck because I needed it for moving furniture into my new house. This made me remove the tonoeue cover once I was ready to move and after reading the captain's post, I realize that my truck did not vibrate prior to my removing of the cover.

Captain, you are a genius. Thank you for figuring this out. With my luck, I would have gone to a mechanic and forked out some serious cash while they "tried" to figure out what was wrong with my truck. Dodge should find a solution though, because the vibrations can be violent at times and I am surprised to that no one has crashed do to it. As soon as I am done moving, the cover is going back on because I hate bouncing around like a bobble head doll! And I can't drive 55!

I put Monroe Air shocks on, and the diff was amazing from the originals.... plus control is great too.... no probs for me....

 

yea the bouncin happens too i usualy speed up to 80mph and its gone.. and i noticed in my mirror that my bed was like flexing. but in that strech of free way all cars cept small cars like civics and mustangs you can feel the bounce. it was fun when i used to date (for a short while) this chick with big ***** going down that strech of free way.. she always kept saying hey watch the road..
