Here's a couple of arc pics for future reference. This is a working system on my 2001 Limited...
Not sure how many of us are still active on here - doesn't seem like many of late - but for those who are (and any that are interested) I've recently conducted exactly the 'trick' I alluded to in my answer to Howard's wisdom provided way back up this thread.
After I stupidly let some 'professional' (a.k.a. muppet) fit my exhaust and do some other work on my Explorer, the rear end never seemed to sit right for many months thereafter. Once we got some decent weather, I got to replacing the rear brakes (completely) and while I was in, around and under, had a fiddle with the ARC once again.
It's still basically Howard's prescribed method but with a little addition and it seems to have worked quite well. What I did was go through the well-documented process but before jacking up the first time, I had a look at where the body was sitting in comparison to where I wanted it to be sitting - and set my axle stands to the required new height.
After going through the usual listed process, I lowered it off not onto the ground but onto the axle stands set at the 'right' height for how I want it.
After that, I switched the ARC back on and flipped the sensor linkage off the ball. I then pushed it up to make it activate the compressor and watched the rear dampers. When they started to extend and take load, I continued until it had just got the weight off the axle stands and then let it stop.
After that, I got out from under, switched OFF the ARC, jacked up and got the axle stands properly clear, let it down, switched ON the ARC.....
and it stayed there!!
I like it!
