Hello and welcome to justanswer.com,
there are four bolts and nuts holding the bearing holder did you get them all? it should come out but it might be slightly seized. you could try tapping it with a hammer, or using a slide hammer tool with a hub adapter on it. You can rent one at your local auto parts store.
please do not rate my answer until we are completely done, you are done asking questions and you can feel comfortable leaving a good or better rating.
oh i understand sorry i got confused with another question.
Well there are no other clips holding the axle on. If you have all the bolts out then you will need to try a slide hammer tool to see if the axle will come out
