Tie rods are generally made up of two components. An inner tie-rod, and an outer tie-rod. The inner tie-rod is an in-line ball joint, the outer has another ball joint, but it is a right-angle ball joint. The threads that connect the inner tie rod to the outer are how the toe alignment is adjusted. There are two different thread sizes available. 14mm and 16mm.
