Never the same corner, just one hub seal a season could be i have been round them all and they are all good now.
It only started once i had put the big tyres on it so had just linked the two together, however as this is about the OP having drive flange difficulties
Back to that drive flange never had one not come out, whacking left and right and keep wiggling it reckon if he has got 5-6 mm it must be pinching somewhere either seal or diff end.
give it the berries i reckon crowbar tyre lever, hammer and keep turning it
