Can you replace the T-case actuator o-ring without T-case teardown? (1 Viewer)

[styran]

I got a 2016 LC 5.7 w/ 70k miles with the transfer case leaking from both the rear axle seal and the actuator o-ring.

Looking at the parts diagrams and service manual, it does not seem you can officially remove the actuator and the shift forks are attached to it.
However, if I split the actuator, taking both covers off with the motors, can I pull the case off with the forks still going into the case?
If the above is possible, I imagine the shift forks have seals to prevent oil from going into the motor, any ideas on where I find those? The parts diagram shows the actuator as one unit, the repair manual treats it as such as well.
I seriously do not want to tear down the case for just an o-ring.

Got some pictures of both leaks below:

the axle appears to be leaking much less than the o-ring for the t-case actuator.
I replaced the fluid for the first time yesterday and it was dripping out of the fill hole when I opened the plug, so the leak is insignificant for now.
Thanks

Confirmed: you can remove 4LO and CDL shells, and then remove the center of the housing body. Make sure to push rods all the way in and clock gears properly on reassembly.

Transfer case actuator issues are not uncommon on the 200-series. Not much documented solutions other than exercising the mechanisms regularly. Here's my attempt to provide more information on where and what the actuator is, how to service the transfer case actuator motor, and potentially...

Are the gears in the housing for each shell timed with the forks?
If so, how do I remove the shells and put them back and ensure everything is still synchronized?

I found this kit containing the leaking o-ring and the seals for both shift forks on ebay.

Everything is in the thread I posted above, with pictures.
