Removal of the locking element from a centre-lock wheel hub with a wheel nut threadingly engaged with the wheel hub, where the locking element engages with the wheel hub and with the wheel nut thereby to prevent relative rotation of the wheel hub and the wheel nut, is made easier by fitting an extraction apparatus having a first end with an externally threaded section, threadingly engaged with a corresponding internal thread of the locking element, a second end provided with an engagement element for imparting rotational torque to the extraction apparatus, and a bearing surface, located radially outside the externally threaded section and axially displaced from the externally threaded section, contacting the wheel nut. The axial extent of the threaded engagement between the extraction tool and the locking element should be at least as long as the axial extent of the engagement between the locking element and the wheel hub and/or the wheel nut. This ensures that the locking element can be completely removed. The extraction apparatus is preferably provided as two parts, an extraction tool on which the externally threaded section and the engagement element are provided, and a spacer tool on which the bearing surface is provided. The spacer tool can be an annular element of suitable dimensions.
