I get a rumble through the truck when I stop.

1) This is only noticeable when the truck is 7/8 to 3/4 full of fuel. Any other time it cannot be replicated.
2) Coming to a stop a little harder then normal seems to make the rumble more apparent.
3) The rumble does not have the same intensity every time, some times its faint some times its rough.
4) The idle doesn't change when this happens, I only say this because the feeling is similar to a misfire.
5) I can also replicate it while sitting in traffic by simply letting off the break and then stopping again without touching the gas. which leads me to believe RPMs or the downshifting of gears have nothing to do with it.
Its a 2016 5.0 with the 24Gal. fuel tank and 4WD w/locking Dif.
Has anyone else dealt with this?

DignifiedDevin: I replied to your post on the other thread. I never noticed the fuel tank level when I tried to replicate the problem. Hmm...
Everything else you have listed though is on the money. I can come really close to a complete stop and just let off the brake ever so slightly and slowly roll, and it won't shudder. It's only when I press firm on the brake and come to a 100% complete stop... wait a second... shudder. Then it'd immediately go away.
Between not wanting to feel the shudder hoping it would correct itself and go away, and the auto start shutting down the engine and a quick stop sign... I usually "try" to soft brake and just slightly press the brake enough so the brake pressure wouldn't be high enough to have the auto s/s shut it down. Stupid I know. I shouldn't have to do all that.
I also posted about this on another thread here: https://www.f150forum.com/f118/2017-...3/#post5440400
more ideas, more two cents, more knowledge and help can't hurt, right?

I would say Tareed and I are having a more mechanical issue.
Tareed:
Maybe we're experiencing the lack of zinc coating in leu of grease like the video I posted says? I don't know if they grease the splines on the 15-17's or run them dry?
I am beginning to think it's probably worth my while to schedule the dealer for a look.. The only thing that sucks is it does appear to be somewhat sporadic.. But since you described exactly to the T what I'm feeling on my truck, I'm willing to bet this problem may already be on Fords radar.
I definitely do have that huge 1 piece driveshaft like in Ford tech Makeulokos video.

2016 5.0 4x4 with electronic locker and 3.31 gears.
Mine is so intermittent (like I said, haven't noticed it in a while) that it would be hard to test. That's why I never took mine in because I couldn't replicate it. I've got 15,000 miles now. How many miles do y'all have?

Mine is a 2016 4x4 as well. But a 2.7eco. 3.73 with rear locker. I'm close to 8k miles on it.
I wonder what your BSM as-built looks like on a 5.0 with no auto s/s
parameter 726-48-02.
It would be questionable "if" the auto start feature was turned on in the parameter even though you don't have auto s/s.
The drive shaft thing doesn't sound like my culprit... I don't feel a nudge, or small kick like described in the video. Just a shake, shudder, quick mis-fire, pee-chill, whatever you want to call it a second or two after I've been completely stopped. I'm still monitoring mine after the BCM mod I did. I'll be driving my truck to and from work everyday this week.

I've got the same driveshaft, not sure if they're greased or not. I may be doing what CeeDee mentioned of soft braking to make it not potentially do that. Because I definitely noticed that unless I come to a full stop with constant pressure it doesn't do it. So I could be saying the mileage affected it, but it could be my braking habit changed.Yours is way more prevalent than mine. Or like I said above, I may have altered my braking habits. I'm thinking yours might be a vacuum leak like Especial86 said. I've heard of people having the IWE crack when installing leveling kits (not sure if you have or not), and getting a vibration when stopping because one of the front hubs is locked in.

Not sure what your original parameters are with Auto Start/Stop but honestly I'm surprised there was even a module for it in my truck.

Interesting. At least the auto s/s (***) parameter is set to off. I know it was far fetched but why not look, eh?! ....I wonder what would happen if you turned on the parameter being that you do not have *** at all.... ?

Good question, I believe all the 17s are now Auto S/S if its an ecoboost, not sure if I'd want to be the guinea pig on that one lol.
