power steering pulley squeak

[PDoyle]

127k miles total with a squeak right at the pulley on the P/S unit. Would just the pulley go bad? I have a new belt. Should I install that to try to lose the squeak?

Hoping the noise goes away after spraying the pulley with a little white lithium grease.
Anyone else have a p/s pump go?

When was the last time the belt was changed and how fresh is the PS fluid? Does it happen only when cold?

Thanks. Guess that is step 1. Just went through the online Lexus service records and I can't find any record of the belt being changed. So how far do I go now? Just the belt and a couple of pulleys or is this the time to do the water pump and / or starter? Argh. Both are working fine btw.

Ive got a squeak too. I think its a pulley, only starts doing it after the its been running for a while and everything is warmed up. Maybe tensioner? Trying to diagnose.
