Front axle seals 99 burb 4x4

I am looking for some help for the replacement of the front axle seals.To do the right side seems to be straight forward.The left side appears to be a little more challenging.Any helpful hints to remove the left flange to replace the seal would be appreciated.

Found that the left seal was not extemely difficult.A slide hammer with a short handle did the trick.I am glad because the servive manual wants the diff assembly removed.
