What way is it bent ? have you taken all the diff head fasteners out ? That may give you enough wriggle room to get the axle out by leavering up one side to releave the other etc , won't take much . Otherwise its cut the diff housing tubes as the guys have said .
I recently had to use sledge hammer and crow bars to get a hilux center out as not only were both tubes bent but the diff head face and housing area was bent and pinching the head so it would not come out . ( was a modified head so had a bit less clearance than standard
