Vibration

[Neumonic2006]

This is a weird one if I had to guess.

 

After driving a while I get a slow rotating vibration from the front end that you can feel in the steering wheel, you can only feel it between 50 - 65 mph?

 

It doesn't matter if I down shift so I do not think it has anything to do with engine rpm but almost seems like it is coming from the front axle.

 

I called the dealer and they said they have never heard of anyone with the same situation but they are not close at all for me to drop my truck and let them have it for a couple days not to mention it has to be driven at least 15 min usually to get it to start doing it.

Any feedback appreciated

 

Thanks

At that speed a vibration is usually a front wheel out of balance or a bent rim at worse.

It feels like a slow rotational vibration, almost like the front axle is moving real slow at highway speeds and has a bad bearing or something? I guess I could check the balance but the truck drives smooth on pretty much all paved surfaces so I don't know where to start.

See if it goes away when you hit the auto 4wd button like mine does
