I've got a '92 LS400 w/120 Kmi. I just got it back from the dealership after a tune-up. They said I needed the PS pump replaced because it was making the same noise you described. They were going to charge $1200 for parts and labor. I said no thanks and took it to my local mechanic. I requested genuine Lexus parts and he did the whole job for $600. It's now running like a champ.
