Abstract: A wrench for producing unbalanced vibrational forces which are transmitted to a bolt turned by the wrench. The wrench produces counteracting torque forces which act on the sides of the wrench handle to facilitate the production of unbalanced vibrational forces.

Abstract: A method and apparatus for adapting a MacPherson strut assembly to permit ready adjustment of the wheel spindle carried adjacent the lower end of the MacPherson strut. In the method, a drill bit asssemby is attached to the frame of a vehicle to permit apertures to be formed in the upper control member of the MacPherson strut to permit ready lateral adjustment of the strut and, consequently, to permit ready adjustment of the camber of the wheel spindle.

Abstract: A method and buffer apparatus for preventing corrosion in a dynamic load bearing assembly. A resilient buffer material is compressively adjustably positioned between a pair of dynamic adjacent load bearing components in a machine such that the amount of electrical resistance between the load bearing components can be varied without having to disassemble the machine. The buffer material is maintained in position between the load bearing components by compressing the buffer material an amount equal to 5 to 30% of its length to outwardly expand surfaces of the buffer material against the load bearing members.
