Power steering *popped* then became stiff, squealing on turns

Hi everyone,

I drive a '65 Mustang 289 with the original power steering system.

As I was slowly turning the steering wheel while backing out of a parking spot yesterday, I heard a pop and my steering went stiff. I can still turn, but with a lot of effort and a lot of squealing -- the type of squealing you get when you reach the furthest limit of a left or right turn, except now it happens anytime I turn the wheel. And, as I said, the steering is obviously stiffer, as if the power steering is no longer working.

I checked the engine bay and the belt was still there, and there was no fluid overflow or explosion of any kind. Everything looked normal. I checked the reservoir and there was fluid. And, yes, I'm using the correct fluid: Napa ATF 75-205.

Some background: My power steering (transmission) fluid reservoir has been leaking slowly but surely. I've been topping it off and checking it regularly, but I can confirm that I drove the car at least once a few weeks ago with NO FLUID. After filling it up though, everything seemed fine and I was driving without problems until this happened.

So, in summary, my power steering popped on a slow turn. Now it takes a lot of effort to turn and squeals loudly. What's wrong?

Thanks for the suggestions, everyone! I'll go under the car and do an inspection after work. I'll report my findings.
Sorry for the late reply, but you guys were correct! The bracket that bolts to the frame rail popped off.

In any case, I ended up removing the power steering. I feel much more confident in the steering now.

And, no, the PS is not for sale ;)

Thanks for your help!
