power steering pump and belt squeal. please help
I isolated the sound and the chirp is coming from the power steering pump. Now here is where I am stumped. the power steering pulley and pump is slightly misaligned. with the car running, I can physically push the ps pump assembly toward the fire wall and the noise goes away completely, until I let go and it shifts back forward. Once I let go it squeals immediately.
I have also observed that pushing the pump back toward the firewall does increase the belt tension in addition to aligning the pulleys.
Any ideas what would cause this? The pump and pulley themselves don't seem loose, but pushing the pump toward the firewall hasn't bent anything into place. Is there a hidden tension bolt or something I need to take the pump/pulley off to inspect?
Sorry there isn't more info, it got dark on me outside.

Im going through the same problem now.Bought a 2008 RX350 used with 120k. Figure I should do the full drive belt system tuneup along with waterpump and cure the chirps during the tune up. Still chirps ! Now I have ordered an Alternator Decoupler Pulley ( OEM made by Litens ) which is standard apart of tune up nowaday with the OAD Alternator pulley. Wish I knew about this during the tune up and had plenty of room. Just took the pulley cap off with plenty of rust. Some people say take off the cap on the pulley, blow all the rest out and lube it where its cure the chirps OR replace it. Replacing option requires removal and impact or special tool. It's tight in the car but I think I just have enough space once my pulley arrive to swap. Hope this yelp
