Sorry to hear about the shaft breakage. Sucks when something like that happens. I've had my share of backlash problems too. Mine is a little cg-4 converted from manual by adding motors to the slo-mo shafts, originally gearhead dc servos with encoder feedback and later switch to the current belt driven steppers, all done on the cheap. The belts are pretty nice once you get things lined up and tight, they're fiber gator belts and have no stretch and so the backlash I have is the same thing, flaky worm gears...go figure. :/ careful retuning of the hob mount position has been a regular thing with mine.
I use synthetic bicycle grease with good results. I think I used Finishline last time which is a white moly synthetic and waterproof. A good molybdenum would also do as it doesn't thin or migrate.
Here's a link to the original setup. It's somewhat changed now with the new motors but I don't have an album for it yet.

Hope you get it fixed soon! The good fall weather is right around the corner..wind.. rain...bears.
edit: found a pic of the new setup. stepper version |

woot! Bit of running man in there too and the bit I've heard referred to as the bass mouth. This is the other one of those that the hot core makes so difficult. Personally I like the heat depicted more than have a full trapezium visible. It just seems more natural that way for some reason. Probably the way most folks mask at a set point to include it, similar to hdr shots.
My attempts look pretty horrible and I scratched out this year too due to a late fall rebuild/redesign of my diy rig gone awry. I'll get it next time though!
