No more cracks.

Just out of curiosity, is this before or after Cessna put the
reinforced spars (R and S models?) in at the factory? I don't believe
the newer models are prone to this kind of issue, but wouldn't do it
in practice anyway - using the towbar is always better for the
aircraft, and done by hand I don't think it's possible to damage a
172/182 nosewheel.
