Anyone know what tool does this? I was reading something on ISTA but honestly got super confused there on what is needed and how to get it. I will keep reading, but wanted to ask.

There is an ABL function in ISTA for changing transfer case oil. The ABL basically pushes the rod and connects the 2 oil chambers. See the attached pictures for the location of the ABL function in ISTA and a description of the divided transfer case oil chamber system.
