Speed Dependent Vibration/Pulsating Noise

[Western96]

I am struggling to identify a problem with my truck. It has a speed dependent rhythmic vibration (through the pedal/floor) and noise that gets worse as speed increases. The noise is not particularly loud but it is noticeable especially at higher speeds (40+ mph). It also gets worse when turning left or right. Even when going slowly (20-30 mph), the noise does not go away, but it just becomes much less noticeable and extends the pulse over a longer period of time. At parking lot speeds, I don't think I hear anything.

 

I recently replaced one of the front wheel bearings. That was pretty easy to diagnose, this seems a lot more difficult to figure out.

 

I believe this is some sort of suspension problem, but I'm not familiar enough with all the suspension components to have a good guess as to what it might be. I don't see anything immediately wrong under the truck, but I don't really know what to look for when it comes to suspension issues. Any advice?

I was going to suggest wheel bearing or wheel hub. Could just be some exhaust pulsation

I guess it could be the other front wheel bearing, but this sounds way different than the other one when it went bad. Might be able to jack it up with the spare tire jack and see if the right hand wheel has a lot of play in it.
