Thanks for the educational video, I was looking all over youtube or Google and not satisfied with the others videos and your video is straight forward to the point, thanks 👍
You need to explain how 4A prevents binding. When the wheels are turned power to the front is cut. If driving in snow covered roads you should still use 4H. Look at the power distribution screen and step on it in 4A with the wheels turned all the way. You’ll see no power to the front at all.
Sorry I am so slow to respond! No, 4A is not to tow a trailer. Towing has nothing to do with the 4WD settings. Use 4A if you are unsure about road conditions. If you know the road is slippery, just use 4H.
I have a 2012 F-150 Lariat 4x4 4.0 8cyl. I have yet to use 4A, 4H or 4L. Do I need to use these gears to make sure they do not go bad? I drive mostly in the city or highways.
No, just have your truck serviced and routinely have the fluids changed (transmission, differential, etc). Follow the manufacturer recommendations and you'll be set.
4auto is actually worse to use than 4hi your better off shifting into 4hi when the roads are snow covered. Because what happens is the wheels begin to spin in the rear and then it transfers the power and slams the front wheels into motion creating wear and tear on your drivetrain. Your actually better off using 4hi and only using 4 auto for very light applications is weather change.
Good explanation! I have a 2020 F150 XLT 4x4 but it doesn't have 4A. When I'm off road and in 4H, I get the sensation like I'm riding my brakes while moving and a grinding sound when I turn (electronic differential is not engaged). Is this normal? Also, what kind of maintenance is suggested on these electronic 4x4s. My truck has 32,000 and I really want to take care of it properly.
Grinding sounds are not good - go have it checked, that is not normal. Electronic 4x4 maintenance is the same as any type of 4x4. Fluids changed, lube, replace worn parts, etc.
You can turn the wheels in 4H. It will not turn off automatically at high speeds. Why would you hit high speed when you feel you need 4WD? Slow down whe roads are slick! Use 4A if you are worried about hitting black ice or something similar.
As fast as you need. If you feel 4wd is required, the road is probably too slippery to take it more than around 40-60. Consider your conditions, just as you would in 2H.
In 4x2 or 4x4 High modes, the electronic locking differential will automatically disengage at speeds above 25 mph (41 km/h) and will automatically reengage at speeds below 20 mph (32 km/h). • In 4L (4X4 low), the electronic locking differential will automatically disengage at speeds above 62 mph (100 km/h) and will automatically reengage at speeds below 56 mph
😅 I have the same FX4 too. It is my belief the E - locker should lock all four wheels together. I had a new 1997 Chevy work truck that came with full lockers. I think FX4 being an offroad vehicle it should have full lockers too. My FX4 doesn't have 4A either. Ford drop it in the FX4 for some reason, perhaps it was there were full lockers instead?
If you need 4x4, I hope you're not going 80. If you need 4x4, you should also be able amd prepared to brake If another vehicle spins out in front of you.
You can’t go fast with the rears locked. They disengage at like 40 km/h or something like that. 25mph. It does this automatically as protection from stupid drivers. Nothing wrong with 4 high at hwy speed btw. But it’s harder to stop. Why drive that fast in poor conditions. ?
