Took car out today for first time in a month and finally it's running good again

But twice I popped a losi axle out of the losi diff cup
Strange thing is I can't bend the rpm a arms enough to pop axle back in
So I have to remove wheel unscrew top pivot screw out all the way
Refit axle and refit screw and wheel

So they must flex a fair bit for them to pop out when it takes so much to pop them back in

I can't run longer diff cups cause once the wheels are on full droop the axles touch the edge of the cup
Maybe that's what's making them pop out when the suspension droops and axle locks on one of the two
Side grooves on the diff cups
Might have to stop suspension dropping so much when in the air or when doing cartwheels
