Have you pulled the axles out yet if it does have a retainer what youre probaly thinking of is the flange that holds the axle on because the bearing would be pressed on the axle,

yes axles are out. no retainer clips. ya there is something pressed on the axle right after the bearing so thats called a flange?? should that come with the bearing?

No that probaly come with the axle is the bearing pressed onto the axle,
