hi,
you don't say how long your cheater bar is or how much you weigh..
but ...'normal' is like a 3 and 1/2 foot cheater bar with 170 lbs or so
standing on the end of it .

if you are not making it 'that kind' of tight, you are probably not getting
it tight enough.

it's unlikely, as least 'normally' that something is giving away slowly ..
you are tightening  just  inner bearing races and a spacer ..just solid
metal.
and I can't image the drum is crumbling ...but the rust I've sometimes
......wow.

probably not getting it tight enough.
