ABSTRACT:
A vehicle tie rod adjustment device for changing the toe of a vehicle wheel by adjusting the overall length of a tie rod assembly. The tie rod adjustment device generally includes a housing, a gear train, an adjustable gear head, and a nut runner. The pivotal gear head threadably adjusts the tie rod assembly by rotatably engaging a hex or flatted portion and a lock nut, and includes one or more roller elements spaced around a guide fork recess to reduce a sliding friction with the tie rod assembly. According to another embodiment, the tie rod adjustment device includes a locking mechanism for maintaining the adjustable gear head in a proper alignment so that one or more components of the gear head can be removed.
