Question 4x4 no worky

My old man's truck no longer has 4x4. Looking to do this repair myself; what am I looking at?
It's got auto 4x4...would like to know how those Hubs work? I heard vacuum?

Yes, vaccum operated. Can you manually lock the hubs in and does it work?

Check the hard vac lines to the hubs, Can you put it in 4wd low and verify the TC is actually working?

It used to with manual lock, but now it seems even when they are locked, 4wd wont engage. Will get more details when I try it out myself...

Alright...here is the actual issue... not as bad as i thought.

4x4 works fine, with hubs "auto" or "lock", but when used with hubs in auto, they still stay locked when the switch is at 2WD.
So, mileage is worse and it knocks like a bastard when turning at full lock on pavement...

I switched to Mile Marker hubs a few years ago. They are a great design and cheaper than Warn.

I had to put a set of hubs on my 00. I used warn and had great luck. But I've heard good things about the mile maker hubs as well.
