I had a similar problem once, when my Cybot had a broken castor - I found
that the Lego axle made a snug fit in the cavity intended for it - however
it was bending and under a lot of tension. My solution was to use
axle-joiners(http://peeron.com/inv/parts/6538a) and 2 unit long axles
alternately - which makes it somewhat stronger. I tend to avoid castors in
my designs when possible though. It lasted (with no broken axles) for the
month or two it took me to get the replacement castor.
To keep the bend low, try and keep the pivot axle as short as possible -
but secured well, and the offset small.
