GL-4 or GL-5 for Transfer Case

[rasmeidirt]

Can I use GL-5 in the transfer case?? As far as I know the transfer case does not have sychromes.
96' Sidekick Sport 1.8l auto JX.

It is your car  can do as you please.

GL5 (only) is rear axle (or front with 4wd) axle lube. (extreme pressure hypoid gear lube ) GL5 must be used in axles or the ring gear fails. hard.

it only has 1 problem is yellow metal damage (brass) there is no brass here. so.....  (and is brand specific this effect !!!)

it might make transfer case shifting harder? , IDK never tried doing things wrong, I buy only correct lube, or  here in texas , we have GL3/4/5 lube all one,.
works too.

I do not think i can damage any thing. (not mixed with other lubes that  it) answering for full lube change out,.

IIRC< IDK and good luck. YMMV

Please help confirm the available gear oil here.
They are in a city far away! I asked them to send some pictures:
