Power Steering clicking noise when the steering wheel is turned fully left or right.

Usually, when I turn the wheel to the left or right limit, I can hear the pump strain, but that is the extent of the noise. Lately, if the steering wheel is turned to its limits either left or right, I get a continuous clicking noise until I back the wheel off slightly. This has started in the last week. I haven't changed anything or hit anything. Any ideas what might be going on and what I should look at replacing? Thanks in advance for the help!

Hopefully someone will answer this for you. I don't know what is going on here. I'm not very technical. I'm going to post steering system diagnosis information in the next post - maybe that will help somebody think of something it could be.

I think the answer is in your own words. "until I back the wheel off slightly".
I was always told not to hold the wheel against the lock position because of the strain that you can here is happening under the hood. Stay backed off just enough untill you do not here that strain. What exactly the clicks are I do not know but if they happen at lock position then don't go there.
