You may need to replace both the lock and housing. There is no way however,
of doing this without removing the wheel. The good new is that it is really
easy to remove and replace the wheel. Make sure you mark the wheel and shaft to
index it for replacement.  You will need a two finger puller to remove the
bushing and lock housing. Replacement is made easy by placing a block of wood down
by the pedals to support the upper steering shaft during replacement. I just
did this to change the ignition lock/switch in my Syncro. Email if you have
any more questions. Good luck and happy new year, Joe in NH
