Okay so Im starting to hear this noise, sounds like its coming from the driver side front tire. It kinda sounds like a hydraulic pump, but much deeper, and as of what I can tell it happens more around 55mph + and when im hitting a lot of bumps. It may be something binding, im not sure im at a loss with this one, I pulled my locking hub and drove it and its still their, sometimes its more consistent then other times, and I do feel a slight pull very slight pull in the wheel. Im stumped.
Forgot to mention its more consistent on the highway.
