I have the old D30 with the vacuum disconnect axle. The arm inside the vacuum motor that slides the collar in place is rattling. I have mine rigged to be engaged at all times because the vacuum lines were becoming a pain. The rattle is due to the arm bouncing and hitting the motor housing.
Does it sound like the arm is worn out?

Yup..there shouldn't be enough vertical play in there to allow you to hear anything. I wonder if you could tack weld that collar on one of the axle halves (preferably the inner) to keep it from moving and just forget about all the vaccuum sheot all together? The cable setup is cool too, but i think with a couple seconds and a welder you could just set it up to be engaged all the time. THen if you need to get the inner shaft out, you would only have to grind off a couple tack welds.

I would not weld the collar to the outer shaft though...would make pulling the shaft a MAJOR pita.

Yea, I looked in to that 4x4 Posi Lok, but for $200, I can wait until I have a locker in there. Welding's not a bad idea, didn't think of that. I just capped the vacuum valve ends for a whopping $1.99.

Damn, now I need a $12 arm, this project's getting expensive. <IMG SRC="smilies/biggrin.gif" border="0">

I've got a TJ, so I don't have that problem, but I wish I did. A buddy of mine has a YJ and was having a problem with the diaphragm. He installed the 4x4 Posi-loc and it is awesome. It was a little stiff at first, but is fine now. You can't beat 2xlow. Wish I could do 2xlow in my TJ for only $200. <IMG SRC="smilies/skull.gif" border="0">

I love having the thing rigged shut and engaged at all times. I spent $1.99 on a pack of vacuum valve caps. Put it in 4, pul the vac lines and cap the three valves on the diaphragm.

I rebuilt the motor with the Mopar kit that includes the fork, gasket, e clips and bolts. I still have the clanking noise. F' it, I probably ditching it for a CJ anyway, and you can barely hearing over the tires.
