My 07 Ram vibrates at around 55mph and up. It's really annoying and I'm not sure what is causing it. The vibration is felt in the seat and not the steering wheel. I've had the tires balanced even though the steering ejeel doesn't shake. It's pretty much stock except the leveling kit that's been on for about 2 years now. If anyone can help that would be awesome. I've taken it to a few shops and they can't find anything wrong with it...

 

Did you also have the tires rotated? If not, that's next. Also check u-joins in the rear driveshaft.

 

Yes rotated the tires and replaced the u joints in the driveshaft and had the drift shaft balanced and still vibration

 

Does it matter if you are on the gas or not?

 

No, just does it about 55mph and above.

 

If you push the button for tow/haul, does the vibration change?

 

Yup I read about that and tried that didn't work and neither did loading the bed with weight.

 

Gotta be something in the driveline then. Bad tire, bent driveshaft/axle, failing bearing......

Crawl under it, and check everything for any obvious signs of damage. Probably won't be that easy, but, it's worth a look.

 

I'll look again. When I looked a few weeks ago looked pretty normal and clean. Thinking maybe the front cv axle but just a guess.

 

I would think you would feel that more thru the steering......
