LH driveshaft oil seal replacement

Hi all, i have the LH driveshaft oil seal wich is leaking badly...

How hard is this job? is there any special tool to use to remove it?

can i remove it without dropping the gearbox (i thikn yes but never know..!)?

this is the number 8 below :

It can be done with gearbox in situ so its not as bad of a job you can buy a seal removal tool i use like a pry screwdriver and a large socket to tap it in .

ok, perfect!!!

thanks nomad!
