mark1305 Haven't had to replace any Jeep seals yet, but have LOTS of experience with engine/transmission seals on bikes, especially the Ducatis I used to have. I'm lucky enough to have a bearing jobber locally that sells to individuals as well as industry. If you have a bearing supply house nearby take the seal that fit and see if they can match it with maybe even a better one. Have the shaft and housing diameters handy too in case they are really good at determining the best correct seal.

cas6969 Mother father cocker spaniel! Another seal came in today... way too big. Man I thought this one was going to be right. Multiple sites said so, had more specifics that usual, but again, way too large an opening. Only ordering them via Amazon prime now so I can send them back for free (eventually they will cut me off).

The weirdest thing is, I decided to just buy another of what I have in there now, at least to buy me some time. I got that one through Amazon. When I bring it up to "Buy it again", it tells me it doesn't fit my Jeep! (even though it said it did when I bought it last time) That could mean: A. An example of how screwed up Amazon is when it comes to car parts. B. It really is wrong and that's why it leaked so quick.

Lol, when I got my transmission rebuilt, they ordered a Jeep kit, then the guy calls me and says, "hey, is this the factory transmission?", I said, "No, but it is an AX15, like other Jeeps.... the PO 'upgraded' to an AX15....". Turns out, nobody knows where that tranny came from, they tried over 20 different bearings to see what would fit!!

Jeeps.... gotta love 'em, that whole "Its a Jeep thing" is code for 5 trips to the auto store, from my experience.

fishadventure ^^^ that, and the output bearing (not really an output bearing but the bearing on that shaft can be ‘fine’ but have a lot or radial runout that effects the seal. The slip yoke shaft itself could want replacement or at the least a quick polish with 800 wetndry.

What siva said is heading in the right direction imho

The one I took out was a plastic/rubber type that fit flush. The current one if a metal flange type with rubber that sticks out on the yoke a tad. Since it lasted such a short period of time, I wondered if it was truly the right one. So recently Iíve attempted to buy the other style. Iíve ordered two in two weeks, both of which are way too big. Since it really wasnít worth the hassle to send any of them back, for what would amount to a couple dollars, I havenít returned any of them. But at this point Iíve eaten the cost of five seals; thatís adding up. Note that they were all supposed to fit according to the sites they came from.

Iím at a loss at how youíre supposed to know what your buying vs what you need, since with limited exception everything they show says it will fit. Iím also shocked at the size of some of these seals, it would be a big dang yoke for such a small tranny. I guess Iím going to give up trying to get the other style seal. Just order another of the one I have; hope it works better.
I am assuming this is the rear seal? If so the bushing for the slip yoke may be worn and need replaced. That would cause seals to wear very fast.

gehlsurf Crap, lol, than that's just bad luck....

Although, like I said, I found that the housing and the seal were a "weak link", IMHO. 2 new seals leaked when installed and the housings seem to break just from looking at them.

I'm sure some on here will say they've had zero issues for 20 years or something. Maybe they were made better back in the day? Who knows.

gehlsurf Is your Jeep jacked up? And axles shimmed properly? I had the same issue about 6 months ago, got tranny rebuilt, the hole rear housing was cracked and PO used sealant or something to hold it together, and my seal was worn on the bottom side, too much stress from a previous lift, I have currently 3.25".

I ordered an Omix rear housing and seal, seal was ok, but housing was cracked straight from the box. Figured it was the weak link.

So, answer? I invested in a SYE and a double Cardin (spelling) shaft. Been happy ever since. Also put 6į shims under my axle point directly at my transfer case. Been happy ever since. Not happy that I pumped out another $1k or so, lol, but happy with the ride and performance.

Unless you're talking about a different seal?
