Wobble when Stopping

i just added a 2-1/2" leveling kit to my '19 Raptor as well as a new ADD front bumper. I have the Adaptive Cruise Control option, so I ordered the special bracket to re install the ACC module. Of course I'm getting all kinds of error codes so I'm in the process of contacting ADD to make sure the positioning of the bracket is correct. However, one issue I'm having is upon a complete stop, the truck will noticibly wobble 2-3 times and then stop. I checked with a local alignment guy who specializes in raised vehicles, and he does not think the leveling kit has anything to do with the wobble. He feels it's the ACC module because the ABS brakes are also involved with ACC. I also can no longer adjust different driving modes because of the ACC issue.
Has anyone else ever experienced this? If so, what was the solution?

It’s not the acc. You can disable it.

Any ideas what it may be?

I actually had ADD install the bumper, new aftercooler and relocation bracket on my 2018 last year and still not able to get the adaptive cruise control functioning .. I have been back to the dealer several times and they even tried replacing the sensor after multiple times on the alignment rack to verify that the ACC is correctly leveled. So in my case based on feedback from ADD at a "few" seem to never actually function afterwords add to fact that you can not disable it once it is throwing codes whereas the standard cruise control functions as indicated in the owner's manual . So the bottom line is I have ZERO cruz control with no way of troubleshooting it now that the dealer has given up as it has been relocated and no longer "factory" I recently picked up FORscan to continue troubleshooting or maybe disable the adaptive cruise function at that level but just havent had the time.. please let me know if you find a fix! and good luck

When you say "wooble" what exactly are referring to?

When I come to a complete stop, the whole trucks seems to shake once or twice and then stops. Its almost like a vehicle stopping that had bad shocks.

Exactly when did this start?....What was the last change to your truck when this started?

Apparently after he had the lift kit installed. I'd start there. The bumper/ACC has can not make the truck shake when coming to a stop.

Oh yes!....I missed that, thank you...

Does the ADD bumper weigh more than the stock unit. Sounds like it’s front heavy.
