I would only run a selectable locker up front. Lockers can do weird things to handling especially on the street, and they can do it without warning.

My 'Burb has the G80 rear and it seems to work fine. I would prefer a selectable locker but I'm satisfied with the G80.

IMO front lockers are for hardcore off-roaders which is definitely not me.

As for the "auto 4wd" that has nothing to do with the axles. It's just a (IMO) half-assed substitute for a true full-time 4wd with a locking center differential.

If you're off-roading hard enough to know you'll need 4wd, skip the "auto" and just put it in 4 hi.

Auto 4wd is for intermittently slippery conditions (like a paved road that has patches of ice or snow, or heavy rain.) The Auto 4wd works by detecting slipping in your rear wheels and then intermittently engaging the front axle through the transfer case.

Yeah, I’ve read up on how this “Auto” system works before, but for where I go, I definitely need to be able to actually lock up Diff’s. I’ve gotten stuck 4 times this year already and it’s so frustrating! I’ve been looking around at Diff’s but fully open to suggestions to anything which will work with this “Auto” system we have as far as the switch, for selecting only of course.

There are no lockers available for these unless you upgrade front diff to 3/4 ton thats what i found. 3/4 upgrade requires some retrofit also

Did you discover this when trying to solve your own locker issues?

So converting isn’t as straight forward as purchasing and installing locking Diff’s into the original housing at all?
