BorgWarner 4407 Front Driveshaft Leak

What do I need to do to remove/replace the front seal?
Do I need to split the transfer case?

Does this kit include the seal that should fix the leak?

looks like you take the yoke off, pull the seal, replace the seal and reassemble.
if that is the only seal you need dont buy a whole kit

Thanks m_j,
Dudeamanscott, check the tech drawing, as it might be part 50 or could even be part 3 if the yoke nut is a bit loose. Reason I say this almost a year ago I did a Dana 60 swap to my sig truck and I forgot to replace the seal #3, found it after I put in the new driveshaft, thought I’d wait to see if it’d leak so far it hasn’t but the yoke is tight.
