Slight “Bump” When Accelerating from Stop

[ChadRockPSU]

I am having the same exact problem, and have been for the last 5k miles or so. Mine typically happens when the outside temperature is above 65 to 70 degrees. I agree with the group that this is most likely the slip-bump situation that the F-150's experience, but it is sometimes hard to duplicate which is making me reluctant to take it to the dealer.

@Ford Motor Company This is happening to many of us.... and of course, the dealer can never "duplicate" the problem.... SOLUTION @Ford Motor Company ????

Thank you for this post! This doesn’t happen at every stop for me, but at most stops, you can feel the bump. I can’t think this is “normal behavior.” If it is, I’m leaving Ford. I couldn’t get my Bronco in for service until October, but if I can get someone to ride with me, I guarantee they will notice. I’ll drive until they feel it. Sometimes it’s harder than other times, but it’s there often enough it should be noticed.

100 miles - felt it twice so far - 2023 Wildtrak 2.7

I think we overlook and dismiss things initially, just thinking it’s “how things are.” It’s a sinking feeling once I realize there’s something wrong that won’t likely be remedied quickly. Then, if it IS a drive shaft design issue, won’t the new drive shaft do the exact same thing?

Has anyone tried the driveshaft repair kit from Ford on a Bronco?
Seems like a fairly easy fix.

I think it’s normal. It’s an off road vehicle with very flexible suspension and driveline. Doesn’t bother me in the least

I understand your opinion, but if it was normal, Ford wouldn't had developed a fix for it.
I don't like the impact that the drivetrain components is receiving every time the vehicle stops and accelerates.
It may be more noticeable in the 2 doors with the SAS package due to the shorter chassis and the large change in geometry.

Had this bump since day one and even had the drive shaft (I think the front) replaced back in ‘21, I’m now convinced that’s just how it is because it does not cause any actual problems. I don’t even notice it anymore. 54k miles now.

My Braptor just hit 10K and it just started, kinda annoying though since it hasn't done it until now.
