Barre d'accouplement

A tie rod is a steering link that connects the steering mechanism to a wheel so it can be turned.

It transfers the steering motion to the wheel through ball joints at its ends, and its adjustable length sets the wheel alignment (toe).

Tie rods are part of the steering linkage at the front axle. Because steering is safety critical, worn tie rods or their ends should be inspected and replaced by a qualified technician.
