Actually dont know what that's from, definitely not under the axle nut though.

As far as the ear clamps, a zip tie is not going to cut it, but the good news is if you need new clamps you can get what you have on there now off, and crimp new clamps on in about 5 mins. Be sure to burp the air out of the boot too!

I noticed with the ear clamps I had to set them up on the notch that was almost too tight, and then when I clamped it down it was perfect, definitely fiddled for a while on that though.
