strut/absorber assembly squeaking when wheel is being turned need second opinion

I have a 2015 prius and when the care is standing still and I turn it to the right or left I get a squeaking noise. I have isolated to I think the upper assembly of the strut/absorber. I am not having any drivability issue but without being able to fully see how the to part of that assembly is put together I dont know what specifically is creaking or what material is its made out of. So my first question is does any one know what specifically is is squeaking in that part of the strut and if so how serious it is and what are my best options. I was hoping that if its a part of the assembly that is just worn and dry that it could be lubricated some how but its just hard to tell because there is no way to see it. I suppose I could go to an auto parts store and see if they have one I can look at and that might tell me but my hunch is its wearing out and its only a matter of time before it needs to be replaced. Any and all help is appreciated. ive attached a photo of the part of the strut where the nose is coming from. this isnt the actal strut from my car but its the same assembly

 

It has 160,000 miles on it. its only squeaking when I turn the wheel from stopped position, nothing wobbling and driveablity is not currently affected. Trying to find out specfically what component in the uppper assembly is causing the squeak and then determine whether or not I can let it ride for a while or if its a component that can be lubricated to give it some extra life then maybe I can do that.
