So I recently bought a Wltoys 14401 and it’s amazing however the diff cups are loose and not staying in anyone know why?
 
You sure you are not missing a "0" in that platform number? In any case, now is the time to get to know the innards of your RC, and how they work.

Perhaps a pin(s) is busted inside the diff, or the screws have come loose. Instruction manual/parts diagram by your side... get in there and investigate. ;)
The following is from the 144001 manual...

The screws that are circled is where I'd check first.
