Leaking near transfer case?

I’m wondering if anyone can share more information about a leak our van has.

Is this potentially the output seal leaking near the transfer case?

If I'm seeing this correctly it's leaking at the T case output seal leaking. If the fluid is dripping off where the driveshaft is engaging the t case it's that seal. If you do replace it definitely check your pinion seal where the driveshaft meets the front differential those leak often and it's a good time to do it with the driveshaft out.

I believe it’s leaking from the seal between the front driveshaft and the t case. I’ll be getting it into a shop next week. but until then, should I not drive it? Thanks for your advice!

It's probably fine to drive, especially in 2wd. The question is how much fluid is still in the case... if it's been leaking a long time that could be problematic.

I've got my van in the shop and my mechanic says that my transfer case (and driveshaft itself) were damaged when my front propeller shaft u joint gave up the ghost. Luckily he says the frontside differential is ok, but the TC and front propeller shaft need to be replaced.

They are recommending installing manual locking hubs in the front wheels so that I am able to unlock the front wheels and drive out in 2WD as a short term fix. After speaking with some other Delica owners, this seems like a strange recommendation. I am not even sure if the transfer case is holding fluid right now.

Does that recommendation make sense? And does it make sense if the transfer case doesn't hold fluid? Thanks!

Do you have fixed hubs, or the auto hubs? If you have the fixed hubs it makes sense to install manual hubs, if you have the auto hubs they should be unlocked automatically. With the vehicle in 2WD, and the front hubs unlocked, the transfer case and front driveline shouldn't be rotating (maybe a little due to stiction/drag).

If you do want manual hubs you want the AISIN FHM-002 (they are sold/boxed individually, not as a pair).

It appears they were auto locking hubs which is why the manual hubs were recommended to me. Got them installed and will be using an infrared thermometer to make sure the Tcase isn't getting too hot while I drive it back home to get the Tcase replaced. Thanks for the insight.
