power steering problem

so my power steering is whining from the moment i start my truck until i turn it off. when i drive the whine gets louder with rpms. but if i turn the wheel at idle it doesnt increase whining. any ideas? power steering pumps are expensive and i just wanna see if anyone has any ideas before i buy a new pump to find out its something else. thanks

 

Do you see any leaks?

 

fluid level is fine. fluids arent clear but are clean. and i need to get up under it. there is a leak but it looks like the driver side cv axle seal. but i know the steering rack fittings are right over top of that. so yes i do need to look closer at that. but im pretty positive its the axles seal

 

Check for leaks, mine went out a while back, one day it was fine, i crunk it up the next morning and it was whining like a baby, no fluid.

 

k i guess ill keep checking fluid level till the weekend and see if anything changes. hopefully friday ill get some free time to check real good for leaks.

 

Forgot to mention power steering still works fine.
