Do these dog bones take pins smaller than 3mm? Or are you supposed to simply replace the whole unit instead of just the pins? The pins in the rear drive shafts should be replaced as well since they've become very flat, but I don't want to attempt it if the pins aren't meant to be replaced. I've probably replaced close to 100 pins in my previous Mugen, XRay and Serpent buggies and truggies and never had an issue until today. This is the first attempt at replacing pins in a Tekno vehicle.
I replaced 9-11 of them a couple of weekends back. The only one that had issues was the rear shaft of the EB48, both ends split, but I had some SERIOUS wear on that (probably 30% of the pin was gone). That looks like the same one you had issues with. I'm wondering if it's the part or somehow the stress we exert on that small piece? Right off of the center drive shaft on only 1", between diff's, imagine the torque that thing gets hit with. A recommendation I read was to heat up the material first.
So to summarize, I would say yes it's still a great idea to try that first before just pitching it and buying a new one as your chances for success are decently high. I will give the heat trick a try next time as well.
