Not sure how you bent your old bearing

But standard procedure is to grind/split the
bearing retainer to get that off, and then use a press to remove the old bearing. Buy a
new bearing (wide one if it is a GTS) and a new retainer. Press the new bearing onto
the axle making sure it sits against the shoulder, then heat and press the retainer hard
against the bearing while hot.
If the new bearing is the same as the old one, then it should slide into the end of the
axle housing with just a couple of taps with a soft face hammer. Before the bearing
enters the housing you will have felt the axle splines engage with the side gears... this
might take a small amount of juggling to get the axle and gear to line up.
Can't go wrong if you are putting back the same axle that you pulled out
