Hmm. CVDs might be an improvement, or you might just shear off the little pins. I think some beefy dogbones might be an improvement, but in all honesty I havent heard of anyine having many issues like this..

Thanks for your replies, wow I would not be happy if the gearbox split in two

I just pulled the broken shaft out again and noticed that the bearing for the
pinion shaft has been destroyed also. That would explain why I needed to shim the drive yoke
the first time it broke. Maybe that caused the heat build up that distorted the plastics?
Hmm, not sure why the UJ would get so hot though. Unless a little rock jammed in there or something,
causing sideways force and friction...

Oh well, The Traxxas CVDs 5151R have been added to the MMM backorder

At least they're all metal.

I have destroyed the pinion bearings before. The possible wobble that bad bearings could cause may have also damaged the UV joint. I can imagine that some dry graphite lube might be good around the pins in the UV joints. I have seen the plastic stretch around the pin holes after heavy use. I will say that I have had better success with stock sliders than any cvds that I have tried.

Hmm, please tell me you havent tried the Traxxas one, 5151R.

I sold the missus on this truck being strong enough from the box not to
need constant parts replacements. If the stock plastics are holding up for you guys I would definately get some more, but can't find them here in Aus and tower is out of stock ATM.
I guess I can blame the bearings now, they're both destroyed (inner one looks like a hassle to get to). So the question becomes how do I stop that happening again? Well actually I guess I don't know what really started all this off first...
Dang it, I wanted to leave this truck stock for no hassle runnings but one of
the Titans was weak out of the box making for a sluggish drive.
