In my past experience with a failing CV joint, I know exactly what a popping joint sounds like during a turn. I know how to tell when a FWD unit sounds when it's failing. My question is whether it's the same for 4WD.

Is it possible for failing CV joints/axles to make noise similar to a wheel bearing noise WITHOUT having the classic popping sounds while turning?

I notice some mild vibration around 55mph. In a thread about 1yr ago, I proposed it might be engine noise. But, I've yet to confirm that. Many talk about the noisy hwy performance of the VX, but I'm still not willing to give up on any possibility.

Any opinions on the possibility of CV joints making noise running in a straight line?
The CVs can cause vibrations if they're going bad.

First, I would check the u joints on the drive shaft as they will definitely cause vibrations if you don't grease them regularly.

..and put the VX in 4lo on an appropriate surface & make some circles. If you have CV problems, you'll hear them click/pop.
