front transfer box seal

Hi, im new to this forum and my problem is this...... i have a P38 Wreg (2000) auto and the front transfer box seal is leaking, my question is......how easy is it to replace this and how would i go about it????

Thanks

Natalie

Which seal is it?

if its the seal on the transfer box input shaft then the transfer box will need to come out to replace it, not a bad job but its bloody heavy!!

if its a propshaft flange seal then thats an easy one, just whip the prop off and the flange and the seal is behind the flange
