Yes they do have a pulse vacuum hub and the modification I was reading says you can remove the little clip from inside the locking mechanism which makes them live like the newer rangers. I was just wondering what exactly "live" meant. So what you are saying is they would be locked in at all times. Just wondering what the pros to this were, and if there are any cons? So pros, just that you can engage instantly? Does it make them more reliable since they are live? Sometimes I have to flip my 4x4 switch a couple times to get them locked in. Would it solve this or would they still not work sometimes?
Eventually I will go with AVMs...
