there's a small stud that acts as a stop - it's adjustable
not numbered, but shown here about dead center right above the tie rod end, stops against the [light colored] boss on the axle casting - common problem for hard left turns when folks put modern tires on, wider than original - tend to it, or it will polish that cap right off the tie rod and your steering will be gone, maybe at speed .... don't ask how I know
