Im at the point in this swap where you have to seat the new oil seal at the passenger side of the diff. I can't for the life of me get it to go in. we used the socket and hammer method and the threaded rod with big washer methods. Both times the seal didnt even go in a little bit at all. What gives? Anyone have problems with this?

When I did mine, I was also installing an Aussie, so I had the carrier pulled out. I'd suggest going that route anyway, it only takes like 10 minutes to pull the carrier.

.....the carrier is out, I thought my post would have made that obvious. It seems that I got the wrong seal from NAPA. My part # is 11899 and they didnt come up with a 11800 like everyone says they used. Im going to try and get a seal from a different part store tomarrow, because there is no way that I have the right one.

Well while you're stuck on the obvious, get the right part, then try again. Seriously YOU are asking for help then you are gonna come off with an attitude about what should be obvious based on something you didn't say.

Good luck to you.

based on the fact that he tried using a hammer and socket to get the seal in makes it pretty obvious to me that he had the carrier out.

have you tried putting the seal in the freezer overnight i heard that works pretty well

Yes, this is correct. I have a D30 out of a 95 and it has the larger u-joints.... which is a bonus because all I need to get is the passenger shaft out of an XJ to do the mod.

However, I just replaced my seals last year using the stock 3-piece shafts. I had my front axle apart a few weeks ago while installing the Aussie but didn't do it then either. Didn't want to spend any extra money on an XJ/TJ shaft.... plus my CAD operates perfectly. Only problem is sometimes my rubber boot gets pulled off the vacuum motor. Minor irritation.

not sure how this relates but i was told that the XJ non-cad shafts were longer then then the YJs.
even ordering thing like longfield cv axles, they only list the XJ dana30 and not the YJ and a replacement. what's up with that.

The XJ shaft is longer because it's one solid piece and not two smaller ones. The overall length is the same but the XJ shaft is longer than the 2 halves of the YJ shaft by themselves I reckon that's what that is all about.

I know many folks who have used both XJ shafts in their CAD YJ D30s and everything worked out perfectly with teh right oil seals.

Don't know about any length difference I didn't measure them out, but I do use both sides from an XJ with no issue.

If Napa doesn't have the 11800 seal you should try somewhere else most places can cross reference part numbers, Oh and from what i have learned, don't tell them the vehicle, make, model, etc because that will only confuse them. I had a guy argue with me about a U joint for a TJ because he saw me pull up in my YJ. I guess some people can't grasp the concept of swapping parts..

Just so other people know for when they do this swap. I got seals from three different places and none of them fit in. Just for the record I had a professional Jeep mechanic look at my axle and tell me that the reason the seals aren't fitting is because my axle tube isnt machined for a seal up at the diff (pretty much figured that out). Now that being said all the seals I got were WAY to large to fit into my axle tube.

I put my old shafts back in and Im just sucking it up for now.

Thought someone else could use this information and save themselves some frustration and time.

Well that "professional jeep mechanic" is right that is why you can't just get the same seal that is on your driver side dif. I used a Napa 11800 and it slide right in, I have read on here were some people have taken a drimel and hit the inside of the axle tube to smooth it out some. Don't let this set you back, if you have the axles and the parts, do the swap.

It's not needed anymore, several guys just used the shaft to bust it apart.
