I fit the rear main inner race to the shaft (if it has been removed) then install in the case and assemble the front bearings. The rear outer race then goes in with its housing, though it can be introduced before the front bearings are fully home in order to give the shaft some support at both ends.
Don't heat / freeze shaft or bearings - it takes surprisingly little heat to damage them, and freezing will cover them in condensation. Nor should it be necessary. Don't use Loctite if you want to be able to remove them again later.
Definitely warm the case, and if you have to use a drift use it in such a way that force is transmitted through the appropriate race, not through the rolling elements.
I'd suggest testing pre-load of A/C fronts before assembly in the case if possible - A7 Companion tells you how.
