My 1967 just started making a squealing noise when I make a sharp turn only to the left. Power steering fluid is full, I see no leaks. Belts were changed about a month ago and appear tight. Any ideas?

 

Yup, the bearings are failing in the pump. Make sure the pulleys are aligned well because this can ruin a new pump fast. For those that don't know, there is such a thing as too much belt tension for power steering, also puts undue stress on the pump. All you need is it to not slip or wiggle.
