I've got a 231 with a teraflex slip yoke eliminator that looks like it's leaking at the rear seal. I did not do this install, I bought the jeep with it already on it. Can I just remove the rear driveshaft and unbolt the yoke and the couple bolts that hold on the tail housing or do I have to split the case to remove and replace that seal?

If it helps here is the install instructions, I've just never done any work with a transfer case besides change the fluid, so I'm not sure how stuff it put together/held together.
