For quick, professional loosening and adjusting of stiff tie rods. Required, for example, for adjustment work and when replacing the tie rod end. The special two-part design of the tie rod wrench completely encloses the counter-holding surfaces on the adjustment thread of the tie rods. This ensures even force transmission on the adjustment thread and thus prevents slipping. Conventional open-end wrenches are usually too wide or expand under the high force required. An expensive replacement of the entire tie rod is therefore not necessary.
