HI,

I am sorry that you have not been helped yet. I just came online and saw your question

Does it make the noise all the time, even in park and idling and steering wheel straight ahead, or does it make it only on low speed turns, high speed turns, or other specific situations?

Please remember that I am not there to test drive it or inspect it, therefore I rely on you to provide as much detail as possible. And on occasion I may need to ask for more information or clarification

All the time, low whine/moan, but occassionally louder. Power Steering pump bled and then replaced. No change. Noise is heard in cabin but not outside. Dealer strangely "gave up"

Dealer admits noise is there though.

HI,

Ok, it isnt often that a power steering pump or rack and pinion will create a noise with steering straight ahead and not turning in either direction and just idling.

Remove the belt and crank engine and see if noise is still there. If it is, then issue is not power steering and will need to investigate further.

If noise disappears, then you will need a mechanic's stethoscope. Reinstall belt crank engine and listen to each pulley and component there with the stethoscope to isolate noise. If coming from the power steering pump, then this may be a pressure switch issue

The 2nd dealer reports dealer #1, who replaced the rack a year ago, used a non-oem rack which is not 100% matching up with other parts, and hence the noise. Now, to put in an OEM rack, which the extended warranty won't cover, it will cost $400 out of pocket to HOPEFULLY solve the problem. Does this make sense to you? Dealer #1 and #2 state GM will not help with non-oem issue and GM won't pay either dealer to replace the oem rack.

HI,

Very possible as many aftermarket parts are made quite to the same specs or measurements as the OEM equipment. See this many times.

Because an aftermarket part was used, GM wont cover it simply because it isnt theirs. This applies to the part and the labor. Not surprised by this decision since they didnt make the part that was installed. However, the dealer that installed the aftermarket part should cover it. They made the choice to go with an aftermarket part and should cover the costs to replace it with a GM OEM part. You may have to speak with the general manager or even the dealer owner on this to get it covered.
