Learn how to install a knock bushing on your manual steering rack NSX. The knock bushing is a brass bushing created by a NSX Prime member in Australia to take up the slack in manual steering rack NSXs on the passenger side of the rack. Without it, the stock bushing deteriorates and develops a knocking sound on the passenger side over certain dips and bumps.
