Abstract: A prevailing torque adjusting element, which in the described embodiment is in the form of a sleeve, for connecting motor vehicle tie rod or other turnbuckle assemblies, having a plurality of linearly extending substantially parallel deformations spaced apart around the sleeve, extending substantially the entire length of the sleeve, except for the ends, which deformations hold at least one rod member threadably in said sleeve in a positive, yet adjustable, fashion. Also disclosed is an apparatus and method for forming a threaded sleeve member into a prevailing torque adjusting element of the present invention comprising upper and lower dies, each having notches, wherein said sleeve may be placed between said dies in a predetermined manner to form a sleeve member or the like into a prevailing torque adjusting element of the present invention.
