Abstract

A replacement spindle that can be easily removed for service or replacement. The spindle may have a threaded projection corresponding to a threaded bushing, which may be secured within an axle tube. The spindle may be screwed into place for use, then unscrewed for service or replacement.

What is claimed is: 
     
         1 . A spindle for use with an axle tube, the spindle comprising:
 a spindle body with a threaded end; and   an exteriorly threaded cylinder extending coaxially outward from the spindle body opposite the threaded end;   
       where the spindle body has a flange adjacent the exteriorly threaded cylinder, the flange has a diameter generally the same as a diameter of the axle tube, and the flange has an outer edge with a bevel that tapers outward away from the exteriorly threaded cylinder. 
     
     
         2 . The spindle of  claim 1  where the spindle body comprises:
 the threaded end; 
 a first bearing journal adjacent the threaded end; 
 a spacer adjacent the first bearing journal; and 
 a second bearing journal adjacent the spacer; and 
 a collar adjacent the second bearing journal, where the exteriorly threaded cylinder is adjacent the flange; 
 
       where the threaded end, the first bearing journal, the spacer, the second bearing journal, the collar, and the exteriorly threaded cylinder are coaxial. 
     
     
         3 . The spindle of  claim 2  where the threaded end, the first bearing journal, the spacer, the second bearing journal, the collar, and the exteriorly threaded cylinder have an axial bore therethrough.
