steering noise

[liron sasson]

hi, I have strange noise on my Kj 2006 2.5" lifted.
while driving at 30mph and up and especially on the highway
the noise is like "trrrrrr" Like the noise of friction, and you can fill it inside (like small vibrate)
It happens if the steering wheel is turned to the right by 5-10 degrees (vert small turn),just touch it right and its happens, what do you think?

Could be air entering into the system.
Check/inspect Steering lines for a potential pin hole leak.
Raise both front wheels off ground, then turn 15 X back & forth to eliminate air in system.

Check wheel bearings as well, especially the left one
also another source, although turning left or right does not matter, is the rear CV on the front driveshaft . If the boot is gone/ torn then it is toast anyways
