    Good morning. I was wondering if anyone knew the technical term for the air valve mounted on the top- fwd-driver side of the trans for the power divider.Has 3 or 4 airlines going to it. When i push the button to lock the rears I have a bad air leak and need to change it. Im trying to look it up but no luck with its actual name.

    Slave valve. A-4688 and A-5000 are two #’s that come to mind.

    Power divider valve is on the front differential for the inter-axle lock. Usually only has one 1/4” or #4 hose going to it.
