On my S-10 Blazer, you have to remove the pulley to get the steering pump
out. Advance Auto had a puller for $25 or so. It was a lot of work, about
three hours to change the steering pump.

Important: When replacing an alternator, it is essential to replace the
small bolt that holds the back of the alternator to the back of the bracket.
if you don't replace this bolt, the bracket breaks abotu two days later, and
you have to go to the junk yard and buy anothr bracket. And spend about
three hours installing the replacement bracket.

DAMHIKT.

Is there a bolt behind the pulley, I had a blazer that you had to pull the
pulley to get to the bolt. I thought it was crappy engineering on GM's part.
The pulley just pulls off and presses back on there is no bolts or set
screws holding it.
