2011 MDX steering whine

Have the dreaded steering whine and will try to change the O rings and PS fluid first before I reach out to the dealer.

Does anyone know the O ring part numbers?

I believe the lower ring is 91345-RDA-A01 and is orange. Not sure about O ring part number on the high pressure hose above it.

There 4 o-rings in the expanded diagram.... Do you know which one is the high pressure one?

Try replacing fluid first. Mine whined after exiting highway, or when very warm. Used 4 bottles Honda spec fluid - suck/fill with turning lock to lock between. Whining gone.
