Moan / groan in am when cold on start up / first moving 3.5L 4x4 ecoboost

Hey all,
When first moving my truck after letting it warm up, as I pull out of the garage, the truck moans, almost like a leveling pump is activated or something. Is this the electronic steering?

Also when are you all dropping your tranny pan and changing filter?
When are you all flushing the coolant?

ANyone know if adding a larger tranny cooler is beneficial?
I heard that these coolers have valves that runny the tranny in the 190s on purpose so a larger cooler won't help.

Brake vacuum booster pump is wearing out. Be careful when you pull away and have to stop if you hear the pump running. After 20 seconds all is good as engine vacuum picks it up.

Some of us have had issues with the integrated wheel bearing (IWB) assembly and it goes back many generations. It’s more of a mind grinding sound coming from the front of the truck than a “moan”, but another option to consider. There’s a sticky in the 2015+ forum that includes a link to a write up for the older trucks.

What year is your EB? There isn’t a lot of traffic down here, so you might get more specific answers by asking in the forum section specific for your MY truck.
