i’d try this as confirmation but what you’ve tried and found so far points to needing hubs. Now you’ll feel better spending the money knowing it’ll fix your issue and you’re not just throwing expensive parts at a problem. All that with just a few extra minutes.

Mile Marker hubs are good ones for the money.

I have been watching this post... I don't want to threadjack this, but I am changing out my OEM auto lockers for Warn manual lockers. What is the best way to cap off the vacuum lines for the auto locking hubs?

Can I pull the fuse for the vacuum assembly (9H465) itself? Should I pull the line off the hubs and put a physical cap over them? Can I disconnect the line as some point in the line harness itself?

thanks

You can just unplug the power from the pvh solenoid that way it wont open, so you won't have any vacuum going to the hubs.
