Well, I have a revo that was a slayer that came with OFNA 17mm adapters. After converting it to a revo and running larger MT wheels/tires it became fairly evident that since there is nothing but the threads of the axle supporting the end of the wheel hub that wear and slop soon develop.
This causes the wheels to wobble a lot and your steering changes as well as you toe-in and camber. So, I ordered a new set of traxxas 17mm hex's off ebay, but while waiting, I thought I'd try something first. Since my hex's are already worn and sloppy, I figured the worst I could do was ruin them.
I bought 10 5mm standard nuts at my local hardware store. I screwed them all onto a long 5mm bolt, with enough bolt to put it in the chuck of my drill. Put the drill in a vice, then spent the next hour grinding them down to be 6mm OD "bushings" with 5mm threads. It took 2 per axle, so I only needed 8.
I also bought a 6mm bit from the store and drilled my worn hubs out fully to 6mm (vs just half that it was originally). With the bushings in place, there is almost no slop at all. Hopefully, they don't work themselves off. I did put locktight gel on them as I screwed them onto the axle.
I figured going with steel nuts would prove to last longer than using aluminum. Even though aluminum would have been much faster to grind down.
Pics to show you what I'm talking about:

Hopefully this will keep that slop at bay. Would probably also work on my aftershock since it's running the same hubs in a similar way. I don't drive it much anymore, so the slop hasn't had a chance to show itself.
