Questions?? D8 Front Aluminum hub installation question.....

So I ordered and recieved the aluminum front hubs for my D8. Kinda confused on how the installation is supposed to go. There are two ballstuds that have 4mm threads, and 2 fixing balls (hotbodies name, not mine). I would think that the ballstuds would be threaded into the hub and then be able to connect to the camber link.....only problem is that the holes in the hub are only threaded for a 3mm screw. What am i missing here? Am i supposed to just use a long screw that goes thru the fixing ball and into the hub?

I just did the same and was a little confused that they would send the 4mm ballstuds that don't fit. So I just ran a 3mm screw into the hub. I still am leary because I broke 1 screw inside the hub without a very hard hit.So if there is a better way it would be great to know.

Are you talking about camber link attachment as on page 19, B12?

So im wondering if maybe these Lunsford ballstuds would work since regular
3mm screws like to break so often....http://www.lunsfordracing.com/mm5/me...gory_Code=BALL

titanium is not really the best to use in this application... i would use a stainless steel screw.. they would hold up allot better than the titanium screws

I left you a pm with my phone # if you want me to try and walk you thru.

kgombe beat me to it.

For the others- if you are using 3mm order some HD screws that are slighly hang out the bottow. Easier to remove vs drilling after a break.

Thanks for all your help guys. Guess i'll just use a long stainless screw and drill/tap if I need to. Just wondering why do you say titanium isn't the best for this application? Just wondering, not arguing.

titanium has better strength to weight ratio and can be using in most applications on an RC car.... but when you have an application where possible sheering might occur (as in the case with the hub and how its mounted) the titanium does not have much elasticity in it.. and will most likely sheer right off...

Gotcha, that pretty much explains it for me. So i'm assuming that a stainless screw would first bend some before the actual shearing would occour?

correct.... just keep regular maintenance on them and have screws to replace if you have to....
