Abstract
One steering column assembly includes a jacket, a bearing, and a steering spindle rotatably supported by the bearing and at least partially extending inside the jacket. The spindle includes a hollow outer tube and a hollow inner tube. The outer tube has lengthening and attachment sections, and the attachment section has transition and connection portions. The lengthening section adjoins the attachment section at an end of the transition portion, and the transition portion is between the lengthening section and the connection portion. The lengthening section has first and second portions, with the second portion being between the first and transition portions, and the outer tube terminates at an end of the connection portion. The inner tube is press-fit into the outer tube, and an end of the inner tube is adjacent the transition portion end. The inner tube does not extend into either the attachment section or the first portion.
