Hi Guys:
Nylon needs to have moisture in its chemistry to stay srong & resilient. Age 
drives out the moisture and the stuff gets very brittle. Model airplane builders discovered this decades ago and there have been instances of shattering props. 
So, they would place the props in warm water for 24 hours or so and restore the moisture content and a return to a non-shattering state. 

So I would think the same could be done for the gears under recent discussion if otherwise they are in good condition. By good condition I mean not cracked. If its an old gear it looks good but does not have the strength it had due to drying out. Give it the H2O treatment to preserve its continued strength.

For what its worth. 

Cheers,
