Here is a DYI to changing your power steering pump pulley and installing a new pump as well. If you are changing just the pump you will have to swap out the pulley. In my case its the opposite the pump is good the pulley is bad (wobbling) so i replaced just the pulley...if you have a whining noise make sure you replace your o-rings. They are inlet and outlet hose O-rings that can be purchased from your Local Acura Stealership for $5. Also make sure you check the P.S. fluid in the reservoir

 

that video doesnt work for me.
What is the diameter of that pulley? Can you put on a slightly larger pulley? (for performance)
Although the OEM one does look fairly large..
