Transfer case drain plug not tight
I serviced my 2022 F250 transfer case today.The fill plug was tight. The drain plug barely snug. 88k miles, when I bought it at 64k miles I did not see in the service records that the transfer case had been serviced but it must have been because I doubt it left the factory that way.
I got lucky.

Well, I can tell you for example with an aluminum case, it is easy to over tighten. Example ,my Polaris buggies differentials, transmissions etc, the torque is like 6 to 8 lb, You want a crank on an aluminum case, go for it. The next time you pull that plug out the threads will be in it.
Does anybody know what the torque rating is for the transfer case?

Thats good advice.
The fill plug was a lot tighter when I removed it than the drain plug and I didn't tighten the fill plug up as tight as it was when I reinstalled it.
Since the spec is 20ft lbs I used a 4" long stubby ratchet so I wouldn't over tighten it and tightened it by hand to about a spark plug level.

I put Teflon tape on mine when I changed the fluid 30k miles ago and I didn't torque them but just snugged and they don't leak.
