This spindle was extremely badly damaged which is clearly visible from the picture.
The drive dogs and taper were welded, also filling in balance holes and air holes. The drive dogs and taper were re-ground. The air holes were spark eroded and the taper was chromed and finish ground to OEM gauge line.
In this case we simply replaced the Ceramic Bush and repaired the Drive Dogs.
This gallery shows our capabilities of carrying out repairs to a complete Assembled Unit. As you can see from the Pictures these Drive Dogs were welded and re-ground whilst still a Complete Unit.
