It connects the axle to the frame or hanger to control fore/aft movement and maintain correct axle alignment. The threaded adjuster lets technicians fine‑tune the wheelbase after suspension repairs or when alignment is off. Replacement is typically needed when the bushings are worn, the rod is bent, or alignment cannot be held.
