BTDT.  Have achieved functionality for 2-6 months with
that approach - tried in 3 cases.  I'm not inclined to
go through the agony of tearing apart the dashboard,
only to have to repeat the process in less than two

I dunno.  I've had a whole bunch of cars for over 300k
miles, and this problem surfaces only on the European
cars.  I think the last time I peered into the dash of
an Asian car, I noted the worm gear was brass.
Probably the installation method was to heat the gear,
and place onto the cold shaft, then let thermal
contraction create the required friction fit.
Something tells me that it's a whole lot easier to get
to these assemblies on a bike.  I'm a major advocate
of not having to fix anything, but since that's an
impossibility for the price class of vehicle that fits
my budget, I at least try to go for "only ever have to
fix it once".

You need a new shop ;)  If the speedo isn't working,
then it's not the gear.  The gear is internal to the
odo, and has nothing to do with the speedo.  So, when
the gear fails, you still have a functioning speedo,
but you no longer count miles.  My speedo works just
fine, but the car no longer ages, it just breaks while
sitting still ;)

I followed up on the earlier posting recommending Palo
Alto Speedo.  $165.  I also found the reference to the
shop I once used in Denver and called them.  Their
prices have doubled, and they're now $100.  Both shops
are a trip to UPS for me, so I'll send it to Colorado.

Thanks, all!
