Well, upon stretching the last Flexx boot over the axle, it slipped out of my hand and tipped over on the ground...and damaged the boot b/c it was stretched. When I stretched it to pull it over, it tore.
I went and bought a cheap knock off from a local parts place, and it tore in 2 parts upon stretching! Anger building...
So, I'm on the look out for a local source for the proper Flexx boot - also might try the Dorman from Autozone...
