Freeze and heat cycle might help loosen stuff.
However, right before trying to unscrew, it is important to consider the materials.
I presume that the hub is made of aluminium, and the bolts are made of steel.
So, if you heat it up, aluminium will expand faster and more than steel.
If you cool it, you get the opposite effect - so it might make things worse, more difficult.
