A wrench having a specific configuration which permits it to be used in tightening a nut which secures a yoke of a yoke/universal joint assembly with the end of a shaft of a drive shaft assembly of a vehicle. The nut is generally seated in a recessed opening in the body of the yoke between a pair of extending trunnions and is secured to a threaded shaft on a stub shaft which extends into an opening in the recess of the yoke. The wrench includes an elongated handle, neck, and a nut engaging head. The neck is provided with specific curvatures which permit the wrench to be inserted into the yoke and a handle having cutout side surfaces which permit the handle to be rotated in a wider arc than could be achieved with a handle having straight sides. The head is provided with an extending portion having an internal nut engaging portion for engaging the nut. The extending portion is provided with an external diameter which is smaller than the inner annular surface of the recess to permit the extending portion to 'reach' into the recess so that the internal nut engaging surfaces may encompass the nut. The wrench permits the nut to be rotated without disassembling the yoke/U-joint assembly, as is usually required.
