Newby - '99 power steering pulley question

I believe that the pulley is correctly aligned when the face is flush with the end of the shaft, but I could be wrong. Just make sure the shop presses the pulley on properly! I've heard of some auto parts stores taking it in the back room and using the ol' hammer.

As for the noise, it's a common complaint with Mustang power steering pumps. There are a number of ways people have found to cope with it- mine was to install an underdrive pulley. It doesn't eliminate the whine, but it dramatically reduces it, and that was almost a better result than the increase in horsepower!
