Finished the front diff (GL-5) and transfer case (GL-4), all with Redline.

I forgot what great oil Redline is. The transfer case is quieter and shifts very smooth. And as mentioned no rear diff LSD chatter.

Redline is expensive but the gear oil is in there for 30K. Easy to get on Amazon. I'll still stick with Mobil1 for engine oil.
