more A-arm woes

[mit-eddie!iris.ucdavis.edu!hill@EDDIE.MIT.EDU (Rich Hill)]

After the discussion on A-arm elongation I decided to check my own
Midget.  No elongation but I did find a crack in the top of the arm 
at the point where it joins the wheel (well, not the wheel - rather
the kingpin or some such).  Anyway, this seems a little serious so 
maybe it's finally time to rebuild the front suspension.  Any advice?
Any other things I should look for?  I really don't want my front wheel
falling off somewhere - that doesn't sound like much fun.  Thanks
