Transfer Case Shift Rod Seal Leak

[mudguppy]

i've searched transfer case leak threads and none of them discuss a leak from the range shift rod. this is where i believe my leak i coming from, and when the transfer is good and hot, it leaks pretty well. ["pretty well" = half-dollar sized puddle after about 1 minute once parked]

i've looked through the 34 TMs and it seems as though the transfer needs to be removed and split in order to punch out and replace the shift rod seal. ... and if going through all that, might as well rebuild the rest. that's a good bunch of work.

the second problem is that i'm finding conflicting information on the part numbers for this seal.

so has anyone ever replaced this seal either for a leak or during a rebuild? if so, good part number for a replacement?

lastly, does this sound like a worth-while effort or simply a) replace w/ a good take-out transfer or b) simply monitor oil level an keep topped off?

thoughts?


TIA

I did this a few years ago. I removed the passenger seat and floor panels to access the small cover on the top of the transfer case. There is a set screw and safety wire, which when removed, allow you to pull out the shift rod. Then use a seal puller to remove the seal. Replace the seal and reassemble.

cool. you pulled the seal from the outside or through the inspection cover?

got a PN or how did you get a good PN?

It has been awhile since I have done this; I hope that I remember it right. I believe that I pulled the seal from the outside. I kept track of all of the seal part numbers but they are at work. Should be able to find it tomorrow.

You are correct, IIRC, that's how I did it, but that was quite along time ago.

Done mine a few months ago, i bent the end of an old flat blade screwdriver into a hook ,kinda like a mini crowbar,just hook it and pull,try to make sure you get a double lip seal,first time it was a single lip and started leaking again,the double is working fine,also may want to use some fine emery cloth on the shaft just to smooth it up a bit.

Did anyone every find the seal number? I need to replace mine again and I can't find where I put the number.

Will those also also work with a M923A2 transfer case?

Thanks, Bryan

I am pretty sure that I used two shaft seals; one after another. The second seal stick out slightly but still helps.
