Quaife (operation of a quaife)

[ralexander03@snet.net (Rick Alexander)]

I might not be understanding this as well as some of you do but don't the
loads on the worm gears only happen when the differential is torque biasing?
If so then 95+% of the time they are just along for the ride just like
spider gears in an open dif. Would not be a lot of wear in this case.
