i put the zip tie through the hole, and then added some shoe goo(or what ever strong glue you can get) to keep it form sliding front or back.
i jumped the truck a few time and it never broke, then i got my aluminum hubs and i just replaced it, my other hyper 10 has the same thing and i been running it like that for a while with no issues, ofcourse i never bash that truck, just on road running on 2s.
on the rear arm i did something similar, but it keeps busting the zip tie during bad landings.
