Agree with some of the above.
Hot air paint stripper, rather than an open flame blow torch is worth a try.
Rawlbolt makes a good improvised expanding puller.
Best of all though, is to weld a bolt, head first, to the bearing.
It only needs a couple of spots of weld. The heat of the welding will expand the aluminium hub more than the steel bearing. The shank of the bolt will give you something to hold and pull.
This method never fails and is standard practice.
Any good independent garage should gave the equipment and experience to do it.
Top tip;
For these sort of jobs, go directly to the workshop, don’t go via reception. 😉
