STEERING LINKAGE
Suspension system components couple to the steering linkage at the steering knuckles, and the condition of the suspension system affects steering capability. Worn shocks or struts, for example, contribute to front-end wander.
Tie rod ends are bolted to the steering knuckles. A ball and socket joint in the tie rod end makes this a pivoting connection essential to steering.
In a parallelogram system, steering is transmitted to the linkage through a pitman arm, which converts steering wheel rotation into the back and forth motion of the linkage.
The two tie rods are connected to the center link and through adjusting sleeves to the tie rod ends. The sleeves are threaded to allow lengthening and shortening of the tie rod assembly when the toe angle is adjusted during a wheel alignment.
