you're not getting the jam nut/cone interface tightened enough.. or the threads are worn out/bad from the factory.
there is no other reason for the bearing preload to change.
unless you install the wrong size balls or too many of them... 9 per side, 1/4" diameter, is the most common setup.
and, yes, telling us online mechanics what type of hub your wheel has would be a good idea, next time you have a question about it.
