What’s your best diagnosis of this leak from these photos? This is the center diff and some black box attached to it. The transfer case doesnt seem to be leaking….it’s the black box and particularly it’s “skid plate” that is drippy.
LEAK! Transfer case? Diff lock? I’m new

Local AAMCO shop quoting $1,300 in labor to crack open Tcase.
I think it’s just some seals but due to the electronic Diff lock on the 4R you can’t just pull actuator off like on GX.
just didnt know what the parts are to fix this? Is it just a couple of seals once Tcase is split open?

EDIT: just saw the thread below this one with a how-to video.
I'm chiming late here, but the leaking at the actuator box/transfer case is a known issue I believe limited to the V8 4Runner 4WDs.
I hate to redirect, but I got good info, write-ups, and part #s on T4R.
Basically, drop the case and crack it and replace a couple of seals...if you can't DIY then yeah, $1k+ on labor to replace < $10 in parts
.
I'm on the fence about trying it myself.

What did you decide? Just did mine and wasn't that bad. Snapped bolts on supports were the biggest pain.
