    Steel Constant Velocity Driveshafts pins breaking?

    Hi there,
    Traxxas does not sell just the pins in these driveshafts if they break. Well mine broke while running 2s lipo. I cant afford to buy new ones and I dont care to be without a my car to send them back. Does anyone ran into this problem and been able to find pins maybe for another set of axles that will fit these? It would be nice if I could find a piece of this hardened steel material and cut them to size? I was thinking of a drill bit?
    Any suggestions?
    Thanks a bunch!

    Sometimes going harder is more of a problem. The harder material can break easier, because there is no flex to it. Take chrome sockets to impact sockets. The impact sockets are a softer material to keep them from breaking when you impact them. The stock pins I think are probably pretty hard. You could try a drill bit. Another option may be if you can find some piano wire the correct diameter. It would be a little softer, maybe too soft? but it is pretty strong in that short of a span. Other wise you can use the stock merv axles, they hold up pretty good.

    That's exactly right. Also, hardening is typically performed after machining and it's limited to the surface in many applications too. I'd look on ebay, chop shops sell driveshafts pretty cheap

    Rebuild kit:

    What pins are you breaking?

    EDIT:
    The above is for axle shafts...
    Did you mean axles shaft or drive shaft?

    EDIT #2:
    The second link above should rebuild drive shafts as well as axle shafts.

    not to be rude, but i would figure out why the pins are breaking. They really shouldn't be breaking from a 2s Lipo unless you are driving it into walls and keeping the throttle applied or jumping and landing on the throttle.

    They are the pins in the second link you posted. The pins in the rebuild kit.
