    Wheel kept falling off

    The front left wheel kept falling off from my slash 4x4. The first time was yesterday morning, it falled off when the car was running. I bought some wheel nuts https://www.amazon.com/gp/product/B0...?ie=UTF8&psc=1 and put the wheel back and made sure the screw was secured. Tonight, the same wheel falled off again when I was running it. Any body kown why?

    Is it a nylon locking type wheel nut?

    As above nylock nuts should not unscrew them selves.

    The wheel hex could be stripped and the axle shaft will rotate in the wheel and unscrew itself. I've had that happen

    Or pin is too short and nylon cant bite into it. Medium threadlocker will fix it ;-)

    X2.

    Also, make sure the threads on the drive shaft are clean. If you have any kind of oil on there the nylock will not lock well.

    Zooming in on the photo, the hex looks pretty smoothed-out...no defined edges, along the sides, as well as the 'flat'. My guess is, the nut isn't the problem (or, at least, not the only problem). Time to replace the hex, itself. As mentioned, if the hex is spinning inside the wheel, it could cause the nut to undo itself. Of course, also as mentioned, if the nuts being used are all-metal (steel or aluminum), you NEED to use Blue Loctite to hold them into the axle stub.

    My nut is nylon.

    What is the part number for the hex?

    I guess other wheel hex on my car has similar worn. Should I replace them too? Is the torn hex going to impact the speed?

    I'd suggest replacing the plastic hexes with aluminum ones, on all 4 corners. Even better, you might consider getting the Tekno 12mm clamping hexes...a little extra $$, but worth it. AMain carries them for $18, and they work perfectly work Traxxas (and other brand) wheels.

    Yes. A stripped hex will spin in the wheel and all the power to that end of the truck will want to unload in that direction (path of least resistance).

    Looking at the picture, the hex isn't that rounded. I would out either a drop of Loctite or super glue on the threads and let it sit for at least twelve hours.

    I replaced the hex with this one https://www.amazon.com/gp/product/B0...?ie=UTF8&psc=1 , however, the wheels still fell off. Why?

    The hex in the actual wheel could be stripped out possibly. Only thing I can think of

    I rotated the wheels. But still, the front left fell off.

    I don't see any hexes on the hub. Also, lets see a pic of the nuts you're using and the back of the wheel.

    You might want to take one of your other wheels off to see what they’re supposed to look like. Looks like your missing the pin that the hex but sides into to keep your spindle from retreating.
