Thanks sno-surfer I have replaced all 4 just before this season. Shouldn't have the snapping off problem anymore.Hey I know a couple people that have experience repairing that on sight. Takes them about an hour, includes chips and snacks.
Oh, one of them just responded above me.
(and I can't find the picture I want of them repairing our local search and rescue cat when it sheered off the axle)
