Rear wheel bearing removal

[BlueSky]

While we’re talking Aprilia rear ends with Nick’s torsion bar issue. I need to replace the two rear wheel bearings on one side but have not been able to budge the stub axle and hub from the radius arm mount. I’ve tried a bit of heat and few firm hits and then a puller, all to no avail and because the radius arm gets in the way it won’t fit on the press. I'm guessing this has been a problem in the past as the other side has fairly new sealed bearings fitted and this still has some old RIV's. So is there a tried and true method?
Cheers,
Noel
