What happens when you lock it in 100%? Does that mean 4wd will always be engaged? I was under the impression 4wd on dry pavement is bad for it. (Not to mention gas mileage)
If everything will hook up as-is, that would be great. I'm just trying to better understand all my options here.
They are referring to a "permanent lock". Which means locking the front axle together. It still only engages into 4x4 when you pull the lever inside. You can do this permanent lock, the only downside is that front axle shaft is not balanced from the factory and you may get a vibration at certain speeds. you also may see people then swapping out the axle shaft with a TJ shaft or getting theirs balanced as a fix to that.
If you take the actuator apart it is a little easier to understand. The vacuum slides a fork left and right. that fork slides over a fitting that has gear teeth in it. the 2 shafts sit next to each other under the actuator. when the fitting slides over to the drivers side, the front axle locks together and becomes one unit moving together.
