So I noticed a rhythmic vibration coming from my front end for the past 2weeks or so. I decided to do some testing on the way home from work tonight. At about 55mph, you can barely hear/feel the vibration. Between 60 - 69mph it gets worse. At just over 70, it's hardly just noticeable. It's there weather or not the engine is under a load, I turned the radio all the way down and had the heat on low just to rule those out. Once I cruised down to 50 - 55mph it disappears again. I've searched on here quite a bit and I've seen people mention that it could be the drive shaft out of balance. I'm 99% sure it's not a low tire or unbalanced wheel. Seeing how the truck is a 2009 with 2600 miles, I'm just not sure what the heck it could be! I'm planning on taking it to the stealership since it's under warranty, but I had to vent and solicit ideas. Any ideas or none at all will be entertained!

Last vibration I had was from one of my balljoints. It wasn't really noticeable until about 50-55. But the faster i went the worse it was. Mines a 2001 though, so I don't think you should have any problems like that with an 09.

 

my 08 had the same issue, it was the driveshaft balance in my case

 

Did you end up getting a new driveshaft?

 

I've got an appointment with the dealership first thing thurs morning. I'll keep you posted on what happens. Hopefully it's covered under warranty and won't cost me a dime!
