Front diff seal leak !! Pics/vid

[glennyboy]

Hi guys
I've changed my cv gaiters today and found another thing on my list to do lol !!
Looks like my front diff O/S seal is leaking and possible Output or needle bearing has failed as it seems to have excessive play in the drive shaft flange
Is there a common bearing that fails inside the diff to cause this ?
took a brief video/pic of the problem below

Just wondered who has done one of these before and anything else i should look out for would be a massive help
just want to make sure i have everything here before i start it
