I've been doing some reading around here on the rear diff elocker, and found this thread: https://forum.ih8mud.com/100-series-cruisers/75494-98-99-rear-diff-lock-high-range.html that gives good instructions on how to make the rear locker run in 4Hi. There was a comment that made it sound like a similar procedure had to be done to the center diff to get it to lock in 4Hi. The thing is that my center diff seems to work in 4hi, at least the light comes on solid. I can't find anything else about it, which makes me think it might have just been a bad inference by me.
On a related note, has anyone found any negatives to modifying the rear locker to work in 4hi mode? I'm really just thinking about the snow here and the poor quality of snow removal (or lack thereof)... Thanks everyone.
