Appreciate the confirmation that they are indeed front idler axles. Hopefully I'll never need them which is what makes them strategic spare parts. I've also got a spare complete bogie suspension assembly stashed away. But it was a rusted take-off item.
Figure they aren't making parts anymore and eventually all the spares will dry up. One accident could turn a decent running vehicle into a flower pot. Such was the case with our M29C Weasel when my brother was driving it like it was a new-made 4 wheeler down on some ranch property in south Texas in and out of ditches at high speed. He had a total separation of all four track bands on one side and wound up dug into the dirt thirty feet ahead of the thrown track. Took me two years to rebuild the track (actually did both sides) and it was only possible because I had spares. There are more Weasels rotting away for lack of tracks than there are running Weasels.
I don't let my brother anywhere near my jeep or carrier
Hope your M20 project is winding down Andrew. I'm getting anxious to get started on mine again now that its all torn down. Dismounted the tyres by hand over this past weekend so the rims would be ready when I decide to take everything to the sand blaster. I need to be patient though and wait out the cold weather since I do my painting in the back yard.
