Engine Squeal = Bad Power steering?

Squeal = Bad Power steering?

I think my power steering is going out. When the car is cold, and sometimes after driving on the freeway for a while, I hear a loud squealing when I turn the steering wheel left. I'm assuming this is the power steering going bad. Does this sound right?

How hard is it to replace the power steering?

I'm curious about this too....

check the fluid and also check the power steering high pressure hose.
i replaced my high pressure hose myself, it wasnt that hard. i took some pictures, ill post them up if you need it.

check for leaks in the hose*

also your belts may be loose. that could cause noise i believe.

Thanks guys. I'll check both of those when it's light tomorrow.
