  • Patent number: 5509208
    Abstract: Tools and related methods are disclosed by which vehicle wheel hub holes, lug-receiving holes, and wheel-receiving lugs are readily and accurately measured and correlated with a suitable replacement part of either type. One tool comprises two spaced measuring stations separated by a connector the length of which is adjustable by interrelated length-variable telescopic members. Each measuring station has a projection and a female recess or receptacle for use with lug-receiving wheel holes and wheel lugs, respectively. The two member connector comprises four and five hole/lug scales or graduations by which the part to be replaced can be used to set the adjustable spacing between the measuring stations and with which the replacement part can be precisely located, substantially independent of the technical skill and/or training of the person using the tool.
