ARGGGHH! Power Steering Pump
Ok, so I replaced my power steering pump last fall, had the screen cleaned twice. I was great for awhile. Now Im getting a whine when i first start the car, very evident around 1k rpms, settles down a little after idling, but then whine pretty loud once rev'd above 2k RPMs. What the heck is going on here???

Is it a low-pitched or high-pitched whine? If it's low -
#1) Are you using p/s or a/t fluid in the reservoir?
#2) Did you flush the fluid when you cleaned the screen?
If it's high, maybe your pulley needs to be lubed?

Using A/T fluid per Lexus recommendations. Fluid was flushed before and after screen cleaning (maybe needs another flush). How would I lube the pulley? Its not real high pitched, but at high RPM its fairly loud, pretty much need to have windows down to really make out the sound. I could try Lucas ATF additive...
Sorry about the misplaced thread, although i really dont see how a power steering problem belongs in the "Performance" sub-forum! (If there is a power steering mod to give me an extra 10-15 hp, let me know!

DOH! I found this hose kinked, i straightened it out a bit, and the whine disappeared. I remember Lexus wrote that some hose was replaced. I think they replaced a formed shape hose with this piece of flex hose. I might have to make them fix it. Bastards.
