April  - if no macro setting, back your camera up (i.e. move away from the axle) in order to get a clear focus and shoot at a higher resolution. I can then help you crop your stamping photo so that we can get a close view of it (just send it to me digitally  
griffithjs.ap@mac.com  or I can even alter it to some extent on photobucket).  Experiment with and without flash from different angles watching for washout/glare caused by flash.  Without flash, illuminate the axle stamping with a flash lite or other lite source and shine it so that it is at a different angle than the camera.  This sometimes helps to highlight the stampings making it easier to read.  Good luck.
