Easy Way To Add Extra Strength To The Wheel Hubs
before they break, wrap the ends with elec. tape around the pins..
then take a zip tie and wrap it around the tape.
the tape and zip tie will allow flexibility and keep from going so far it breaks.

since doing this i have not broke a single hub.

trim the elec tape so it is flush with the end of the hub
you can use a black zip tie so it blends, you can also put the lock on the under side and it will never be seen, i did it this way for the pic so you all could see what was what.
