When I swapped my 454, I had to remove the pulley from the power steering pump because I had to fabricate some brackets to bolt it to the 454. Since then, when turning and standing still I got this whinning from the p/s pump. I thought it was going bad, but after carefully listening, it actually sounds like the pulley is slipping on the pump shaft. I was going to spot weld it, but a friend told me that it would become unbalanced and that would destroy the pump quickly. How should I fix this? Any help appreciated.
