Good Morning all, my transfer case has been leaking out the tail for too long and I need to attack it this weekend.  Anything special I need to know, or special tools?  Timken seal good enough for the job or is there something better?  Thank you in advance for wisdom and experience.

I don't recall it being a tough job, just be sure to find something that is the size of the seal to drive it into the xcase with. 

 

I do remember the part being harder than expected to find thou. Can't recall if I had a parts store order it, or I got it from Dodge.

I figured getting the old one out was going to be harder than getting the new one in.  Would we agree to this being called the "output shaft seal?"

That sounds right. 

 

I recall now, the shop that built my 1 piece drive shaft ordered it in for me.

Drill one or two small holes in the seals steel face then screw in small self tapping screws a small amount, use the screws to lever the seal out. Secret is small drill, very steady and grease the drill and seal area to catch the steel bits. Or buy a seal hook. When fitting the new seal if the outer part that will sit against the case is just steel put a little smear of sealant around it to seal it, if its rubber or coated don't bother. Also as been said already find a good fit seal driver like a socket but it must only sit/touch the flat steel portion of the seal and tap it in steadily and square noting how deep the old one was. Also check output yoke for a seal groove as it might have worn,if it has worn you might be able to sit the new seal at a very slightly different depth so it's not running on the wear groove

I changed mine and it's still leaking, checked the vent, all good. Been leaking for like 5 years now, next step is new bushing and seal again. If that doesn't fix it I'll be getting new drive shaft built with bigger u joints, will have to get new pinion yoke. Good luck with yours.

Bearing sloppy? Groove in the output yoke?

Sometimes the soft plug in the end of the yoke can leak, next to the u-joint.

It is called a t case output seal. It can be easily found at NAPA. Take a sharp screwdriver or tool of choice and go around the tail housing and pry the old seal out. Apply grease to new seal around the edges and use a hammer to lightly tap it in until fully seated. Very easy to do. Make sure to loctite those rear driveline bolts. Now is also a good time to do a rear pinion seal if necessary.
