Excellent, as soon as this happens, let us know. But still try pulling the connector, just to see what happens.

Dorman makes a helluva lug nut though.
I agree with all the peeps here. Your level isn't causing any issues

The vents could be a problem, mud may have clogged them. IIRC though, the vents are on the nonvacuum side of the IWEs, I "think" they just allow the air on the nonvacuum side to escape when the IWE tries to close in.

I think that company is full of lugnuts.

Hey guys,

So I had both actuators and half axles replaced with OEM ones. Wouldn't you believe it, there's no grinding noise now in 4wd! Maybe just bad aftermarket parts?

I am, however, now hearing a ratcheting sound coming from the right front hub. It sounds just like spinning a ratchet and I only hear this sound when accelerating. If I let off the gas, there's no sound. Any thoughts?

Don't recall if you've got 4A or not, if so, throw it in and drive like that, until you can get another check valve. You've still got a vacuum problem if you're getting grinding like you describe.
If you don't have 4A, pull the electrical connector on the solenoid. What I'm saying here, get the IWEs to lock in to prevent grinding brand new ones up. As long as you don't engage 4H/4L on high traction surfaces, you won't hurt anything.
I'd do one or other before you drive it again.

You're losing vacuum as you accelerate, let off, and vacuum returns pulling the IWE out.
