Re: 'steering box'
The sector roller lasts longer than the worm as a general rule due to constant movement on the roller gear. The worms take a lot of stress and tend to pit and spall as the surface breaks down. Most of the worm wear is right in the center where it sets most of the time.
The older 2-tooth sector gears wear faster than the roller type sector.
