Rebuilding X Type transfer case
#43
![Default](/forum/images/icons/icon1.gif)
Sorry to revive an old thread, but I simply cannot find the information I am seeking anywhere. I am trying to replace the inner shaft seals on a pre-2004 TC. I've managed to remove the old seals and press out the splined shaft, but have been unable to get the new seals (SKF 10181) to press in correctly. I have tried at least 4 seals and they will not seat into the shaft or press in straight. Each one has gone askew and been ruined. It seems like the seal is too large for the shaft. It seems like numerous people have been able to replace these seals without major issue, so either I am doing something wrong or the shaft on my TC is smaller than normal. Looking for advice from anyone that has successfully replaced these seals as to whether they encountered these issues and/or any tricks to get this seal installed without deforming.

After much trial and error, I was able to find a seal that fit inside the plenary gear shaft of my 02-03 transfer case without deforming. I purchased it from here: https://www.avxseals.com/Shaft-Oil-S.../tc26x40x5.htm (I have no affiliation with this site, but am providing this link for the benefit of others). Ironically, it is spec'd exactly the same as the SKF 10181 (26 ID x 40 OD x 5). It installed easily and I likely wouldn't have even needed a press as a little even force with a socket on the face of the seal was enough to push it into place. It is rubber-covered, which made me a little uneasy (likely not as heat resistant and may be more prone to dislodging especially given how easily it installed). However, I used a little RTV black as a sort of adhesive as a hopeful backup to keep it in place in the gear shaft. I guess we'll see how well it holds up.

Ah, I didn’t know that. Please keep us posted I will be doing my transfer case in a month or so. It’s got a small leak. In the mean time Ive just been pulling the top fill plug and to top it off. I shortened the top bolt and part of the case and now can access the fill plug. I will post pics.

I have a spare transfer case out of the car, and both seals appear to face the same way, i.e. lips facing to the left (toward the rear driveshaft connection) side.
The axle shaft that connects to the right front wheel slides into the case from right to left, so it has to slip through the seal without engaging the lips of the seal.

it makes since that the axle shaft that goes through from right to left and they would be turned that way to not catch the lip. the picture on post #13 looks like the metal face of the seal is facing the left side , or trans. side. atleast that one does. but i couldnt tell about the one behind it. so im puzzled. thanks for your reply
