A method of making recirculating ball nut and threaded shaft, and race and splined shaft assemblies comprising, cutting the grooved shaft to desired length, relatively moving the shaft and ball nut or race to cause the nut or race to move over the end of the shaft and axially along it to a location removed from the terminal end of the shaft, selecting a pre-machined shaft end component having an external bearing surface of the required size for the diameter and length of shaft which has been cut, and having a sleeve with internal groove and land portions, coating at least one of the grooved portions of the pre-machined shaft end component and the one end of the shaft with a hardenable adhesive, relatively moving the pre-machined shaft end component and shaft to cause the sleeve to move over the terminal end of the shaft and axially along the shaft to dispose the pre-machined end component on the shaft with its sleeve covering the adhesive, and curing the adhesive to form an integrated axially extending key between the pre-machined shaft end component and shaft. The invention is further concerned with the product so formed.
