The seal on the transfer case has gone bad on my 2011 rzr 800S. It’s leaking. Anyone know how to deal with that?

Do I have to take the transfer case out (alot of labor) to fix this, OR… can the drive shaft be dis-assembled at the U-joint (just in front of the transfer case) and thereby the seal can (somehow) be accessed?

Will greatly appreciate any advice.
