Ok I guess you might have noticed I got a new camera lol
On To The WK Shaft Upgrade
Ok with Brushless power comes Brushless problems.
You'll need Traxxas parts 2 EA. of part #4928x and 1EA. of part #4951x
got mine on ebay cost around $18.00 shipped
First we need to take out the old shafts.
First remove the ''c'' clip from the lower suspension link on one side and remove the pin.

I used a xacto blade in the pic to do this but found a tiny screwdriver to work better.
Next remove the set screw pins from the shafts.

(ok so pic was of totaled shaft but you get the idea lol)
Now that you have removed suspension link pins, and shaft set screw pins you can spread out the front/rear end and pretty much drop out the old shaft.

OK theres how to take out the old ones.
