Yes, I have:
A local store in Langley BC quoted $598 for a #10 Dexter, complete with brakes
. A store across the border (in Bellingham, WA) quoted $450 for the same.
industries in Abbotsford told me they only replace, do not sell the axles. A replacement would be around $900. For me personally that is out of reach. I can replace the axle myself.
I see axles on eBay (new overstock with some surface rust) for about $200 plus $82 for shipping. Unfortunately non are exactly the size I need. The guy at Escape
suggested that it is possible to cut an axle in the middle to make it shorter, but that is too much work and may damage the axle - not worth to save $150. I may order from Bellingham if I don't find cheaper.
