Hi guys

Well this is my first post and I am hoping that someone can help with my problem. I have changed my passenger’s side front axle seal for the third time now and once again it is leaking. I know that the dif is straight because it wasn't leaking prior to me changing the front diff centre. So I am thinking it must be the way I am putting the axle back into the housing. Is there a trick to this would much appreciate any help.
Cheers

Bernei
