New WLtoys, shocked that there is a problem!! (😆)

Seems like there is an issue with the rear diff. Anybody know what it is? Is it fine to drive with it? Thanks!

Not 100% sure. I have kits that make that noise when spinning the wheels but they do it when either side is spun. I also have kits that dont make any noise when you spin the tires by hand. Id take the diff apart and inspect it.

Alright, I’ll try to do that! Weirdly, if I take the wheel off and pull the throttle the hex spins freely when the motor is powering it but then stops and starts going backwards while the other continue moving forwards??

Wonder if the center carrier bearing in front of the diff isn't a bit sticky.

Run it til something gives. That will find your problem

Great advice. I hate taking cars apart to find the cause of some little issue. Just run it till the issue fly's out. Makes diagnostic faster.
