We added the loctite in an attempt to try and keep things still. Obviously, with a hub that is nearly disintegrating around the bolts, a substance needs to be applied to hold things together until a permanent fix has been applied.

We used the nylock nuts included in the mounting hardware for these hubs, purchased from AndyMark (http://www.andymark.com/product-p/am-2021.htm). These are the correct nuts from my understanding.

Sorry for our ignorance. We simply did not know that loctite eats away at polycarbonate. We are currently looking at other options.

EDIT: Another thing. The center hubs (6 wheel 1/8" center drop) were not damaged as much as the outside hubs. We have been stress testing our robot by hitting defenses as much as possible.
