I've just used a garden hose with a spray nozzle with nylon brush to clean a radiator or condenser. Maybe with an attachment that lets you apply Simple Green or something similar.
I don't think an aerosol can will work on mud build up. Those products are intended for an A/C tech to carry in...
How fast are you going? Is it on all surfaces? Have someone ride in the back seat, or you ride in the back seat when someone else is driving and listen.
I picked Las Vegas because it had terrain that was most like what I'd be driving over. Others pick Moab for the scenery. All Off-Roadeos take in account that many new Bronco owners have never been off road.
Valvoline ran two Ford Explorers with 2.3L engines for 500,000 miles to compare their conventional oil and synthetic oil. The timing chains of both engines lasted the full 500,000 miles.

I see two reasons for changing the differential cover, cosmetics and gaining a drain plug. I don't see replacement front differential covers available. So no need for a drain plug?
After I took delivery of my Bronco I compared my Garmin, Ford Navigation and Apple Maps. Ford Navigation and Apple Maps had their pluses and minuses but Apple Maps is free. I gave my Garmin away.
Thank you for producing an informative video that emphasizes performance instead of cosmetics.
I'd like to see another video showing the PRO performance.
Do the lights have an IP rating?
This is a bit late for you, so it's an FYI for others. I have a cousin who's taller than you, 6'10", who drives a two door Wrangler. He removed the driver's seat and sits in the back seat. He seems very happy with it.
