RE: Killed rear diff on my maxx?
I just few days ago had a similar case.
Out of nowhere rear tyres lost power.
After spending 2 hours disasembling everything i found out that a cross bolt snaped and it was not transfering the power from the transmission to the rear tyres.
What engine are you running? and where do you use it mainly "terrain?"
I use mine on low grass or gravel mainly.
Not many areas close by that have rugged/dirt terrain.
Originaly i thought my rear diff blew.
Check everythinhg and as the others said. if you already broke some it will happen again. But if it lasted you a while and i guess it did judging by the way it looks its prob just best to get a ne one.
They not that expensive anyways.
