Power steering pump question

Professor Fate said

Agreed.
Although I've never personally experienced this, excess hydraulic backpressure is the only thing I can think of that would make the pump completely stop turning at each end of the steering's travel; which to me would indicate that the relief system is not functioning- either a stuck/sticky valve or possibly a pinched return hose, although the return hose seems less likely.

Awesome thanks guys I knew i could count on yall! I've never experienced this before either. I'll tell you another symptom I forgot to mention. It's kinda hard to explain tho. So when the steering wheel hit the lock should be maxed out the belt will start squeaking and you can continue to turn the wheel but the tires don't move. Kinda like on a forklift if you ever drove one. Once you reach the max travel the steering wheel will continue to move but the wheels don't. Its not alot but it does move some
