i got a new revo 1 16 and i noticed the rear diff was making a grinding noise and given me alot of resistance so i called Traxxas and the guy said what i expected tighten the 3 grub screws so i did and i put everything back together
and STILL! the grinding persists and i kno its the rear diffs cuz i took out the center drive shaft and rolled the car on its 2 front wheels and there was no grinding from the tranny or front diffs. so i called Traxxas 2 more times and they said they dient know so wHat tHe hEck!!!!!???????
RC RUNS IN MY BLOOD!
I told you the same thing Traxxas said to do in a different thread.
Just send me the truck and i'll fix it for you... Include some money so i can send it back..
