hey mate,
if i was you i would chuck in a new hub, cost $200 from suzistore here in perth. when i pressed my new bearings into my old hub, there came out really easy and also went in without to much strain. when i was pulling it out the 1st time, the cer-clip wasnt actually sitting in the groove but just half in. the stayed firm for about 15k then became loose thats when i put the new hub in. they should take a fair bit of force to crack or move, just depends on the condition and use. but shouldnt be easy.
here is the thread i made for do it:

1 tip: paint the new hub before you fit it, not sure how you would but it would stop it from rusting (surface rust) like mine has.
i got my bearings from weaves.
