It's a common failure point. I usually add old bearing races to support it.Lost drive when i was doing some backflips with my big rock.
Pulled it apart and noticed the slipper was damaged, nothing else.
Feels like theres alot of plastic parts that should go out first, anyone else had this happened?

Or just slip on an inner race from an old bearing.A new metal slipper hub sleeve was introduced with the new 4s line. It's not available yet though.

I’ve never had issues with the driveshaft connection part of the hub. It’s always where it connects to the rear differential that has issues. I believe that part of the hub is the same for all models. If I’m wrong please let me know so I can go find itThis feels like a side effect of having the updated shorter rear spline on the input gear. I believe they did this to accommodate the plastic nut to better hold the slipper assembly tight... I have not had this happen yet on my older 3S rigs and also have not had too much slipper trouble after getting the Loctite to set correctly in the slipper screw/threads.
I feel like they should have kept the spline longer or used a stronger metal for the slipper metal bits... One step forward.. Not sure how many steps backwards.
One thing is for sure, I wish I had stocked up on the old input gears with the longer splines back when Jenny's had them.
Huh! Interesting… I must find one for grins and check it out.So far, I have not had issues with the center driveshaft connection either.
At the thread below someone had troubles installing their power module after a new slipper, turns out the old diff input gear is longer. You have to scrap the plastic nut in the V3 slipper for it to work.
Seems like quite a bit more contact area with the longer input gear. Especially at that point where you see very high torque to the rear wheels.

That's what I'm using right now. It most definitely helps, but I already have a small crack again. If the new metal sleeve from Arrma doesn't work any better, Oktay makes a slipper housing upgrade. I think it's 7075 aluminum. But it's a German company, so shipping to the U.S. is going to be very pricey.Or just slip on an inner race from an old bearing.
