Abstract: A kit including an axle to be substituted for a fixed flanged axle from which kit axle the flange is omitted and which includes an outward axle extension providing spaced bearings on which a kit wheel hub is rotatably supported, the inner end of the hub providing an annular flange which performs the same function as the replaced fixed axle flange by accepting the bolts normally used for supporting the adjacent brake drum and wheel of the vehicle. Both inner and outer ends of the substitute axle are splined, the inner end fitting into the splined differential socket provided therefor in the differential, the outer end fitting into a conventional wheel clutching mechanism mounted on the outer end of the axle housing hub, the mechanism being operable manually to optionally lock the substitute axle to the wheel hub and wheel or to disengage the substitute axle to permit the hub and wheel to turn freely thereon.

Abstract: A stub axle and inner end flange which fits the outer wheel supporting flange on a fixed axle and is apertured peripherally to accept the wheel attaching bolts of said fixed axle flange, a pair of roller bearings mounted on said stub axle, the outer end of said stub axle being splined, an axle-housing hub rotatably supported on said bearings and having an inner flange, the latter having peripheral bolt holes corresponding to those in said stub axle flange and said vehicle fixed axle flange, a set of bolts for securing a drive wheel disc removed from said fixed axle flange to said stub shaft flange and a conventional wheel hub clutching mechanism mounted on the outer end of said axle housing hub, said mechanism being operable manually to optionally lock said splined stub axle to said axle housing and wheel or to disengage said stub axle to permit said housing and wheel to turn freely thereon.
