Horrible screeching noise coming from power steering pump while turning.
77 pontiac lemans with the 403. Just started it up after wiring it. And the power steering pump is making a horrible screeching noise everytime i turn the wheel. It sounds terrible. I've had brand new front tie rod ends shocks and sway bar. Ive also had my bearings are new. I can't understand what would causing this horrible sound. Fluid is also completely full looks a little brown but not terrible,

How does the belt look? Grab the fan and wiggle it to make sure a bearing in the water pump isn't on its way out as well, could affect belt tension or create extra drag on the belt drive if it's failing.

The PY Online Forums is the largest online gathering of Pontiac enthusiasts anywhere in the world. Founded in 1991, it was also the first online forum for people to gather and talk about their Pontiacs. Since then, it has become the mecca of Pontiac technical data and knowledge that no other place can surpass.
