Hey guys, I'm a member here and this is my video. Please subscribe to my channel. My 14 year old punk son (LOVE HIM) told me that I couldn't get 1000 subscribers because I'm a dumb boomer. For the love of God help me prove him wrong.

Funny. I subscribed to your channel last week! I commented on your cactus. Let's show him what Boomers can do!
 
Excellent video! ? ?

The modes certainly made no apparent difference.
Of course airing down would but that wasn't the point.

Thanks Man! I do remember you saying that. I got that cactus from a buddy that I did some tractor work for. He wanted it taken out and I said NO WAY I WANT IT. So there it lives now in my front yard.

Great video. I can’t believe what a difference applying brake makes.

Great info demonstrating the lsd again. Keep the videos coming its nice to see it for real

The drive modes optimize steering, handling and powertrain, throttle response.

Great videos! While you’re at it, you might think about doing a video on the locking front hubs. I use mine all the time on my ranch truck, which is an old F-250 with the 7.3 Liter PowerStroke. Getting ready to upgrade. Just ordered a 2022 Tremor.
 
I'm the one that mentioned applying the Brake on your last video. A front locker is fine if you're rock crawling or driving in 4 Low. But, at speed, you don't want anything that will effect your steering. In Snow, Ice, Slick surfaces, a Locker will put you in a ditch on your first turn. Because its Locked, it's controlling your front traction, which is also your steering. Simply put, it's pulling at the same rate your Rear is Pushing.

Good call on the cactus. Video was very cool. Keep them coming!
 
Good video. It really shows how the front works and tricks for getting unstuck.

I highly suggest putting this up on https://www.ford-trucks.com/forums/forum279/ for two reasons
1 its full of boomers
2 They had a huge thread about the lockers

I believe you can get to 5,000 subs easy. Also try other forums where they talk about trucks and not just fords, overland forums, boat forums. and Reddit
 
Great videos! While you’re at it, you might think about doing a video on the locking front hubs. I use mine all the time on my ranch truck, which is an old F-250 with the 7.3 Liter PowerStroke. Getting ready to upgrade. Just ordered a 2022 Tremor.

The Tremor has auto locking front hubs, do I still need to manually lock them? If so, what's the point of the "auto". I'm not being a smart ass, I truly want to know.
 
Leaving your Ft Hubs in Auto, or Un-locked means as you drive, you're not turning the internals of your front differential. That saves Wear and Tear. Also improves your mileage because you're moving less. By engaging the 4x4 selector the Hubs are then Vacuum engaged. Thats why you need to be moving for the 4x4 to make a full engagement. When you Lock your Hubs in Manually, the internals of the front differential now turn when you're in motion. Switching the 4x4 selector inside engages the Transfer case. You should be at a full Stop when you select 4x4 Low.
 
I don’t know how the current system works, but I suspect it hasn’t changed much. In my current truck I have three reasons for locking the hubs.

1. I get stuck while in two-wheel drive. In my truck I believe the auto locking hubs won’t engage unless the front wheels are rotating. It takes one revolution for the hubs to auto-lock. If I get stuck in two-wheel drive, flipping the knob to four-wheel drive doesn’t change the fact that I’m still stuck because I can’t turn my front wheels. This may not be true on newer trucks. I don’t know. Hence my request. To demo the manual locking hub, just make sure you’re in two-wheel drive before you get ‘stuck’ and then flip to four-wheel drive. If you remain stuck, manually lock the front hubs.

2. The auto locking hubs are engaged using the vacuum system. If there is a leak in the vacuum system going to your front axle, the front wheels won’t lock to the axle. Usually this leak occurs where the vacuum hose connects to the nipple. The easiest way to fix it is to disconnect the hose, snip the end from the hose (where it might be stretched or rotted) and then reconnect the hose.

3. It’s a good idea to lubricate the the front differential once in a while. If you don’t use your four-wheel drive for months (or years!) on end, as is the case for some road warriors, manually locking your hubs once in a while will cause the axles to turn your differential and get the gear oil to circulate through the system without going into four wheel drive. Fortunately, I don’t have that problem. It doesn’t hurt your truck to drive with the front hubs manually locked.
 
The vacuum hub engagement looks like the weak link in the system to me. If I get stuck somewhere, unexpectedly, I'll simply engage 4WD inside the cab, and drive out. But if I'm going off road intentionally, I always engage the hubs early. This lets the system get all lubed up and it positively locks in the front wheels and keeps them locked in. Neither the manual or the automatic system engages until the wheels rotate enough to line up the splines in the hubs, but that occurs almost immediately and should never be noticed. If we are stuck in 2WD, and engage 4WD, the axle shafts will turn in the front axle, and line up the splines in the hubs immediately. When we turn the knob on the hub to "lock" we are not really engaging the hub. We are compressing a spring that is pushing on a splined collar. As soon as the axle rotates a few degrees, relative to the wheel, the splines line up and the collar slides in, locking the wheel to the axle shaft. The vacuum system can slide that collar too, if it is working correctly.

It seems unclear to me if 4WD high can be engaged while driving with the hubs in "Auto". In theory, it seems like it would be OK, as long as the system can engage the transfer case while driving, with synchros, and then do the vacuum hubs. But the manual seems vague on this. If the hubs are engaged, I see no reason why we cannot engage 4 high at highway speed. This is handy for mountain driving where slippery areas come and go. Of course, 4 low is a different story.
