Powersteering pump squeel

[sage2k]

My powersteering pump just squeeled for 3-4 minutes after i started the car up, i drove a few blocks and it went away. Is this a sign that its dieing? Or do I just need to flush the fluid? Any tips on replacing the pump

Have you done any work to it recently? Squealing on a cold belt can be a sign of pulley misalignment. On most of these pumps, you can push and pull the pulley in and out a little (they have some endplay). See if yours has a lot, or if the pulley is cockeyed compared to the rest of the pulleys (a machinist's edge works well for checking this).

Obviously, ensure fluid is up to par, etc.
Good luck.
