  1. 2021 bronco sport - 4WD module failing

    I had an issue with the RDU shudder noise and had the fluid replaced. Then started to get some error messages about servicing the Advance Trac and 4WD system. Couldn't use any goat modes. The RDU motor actuator was faulty. There is a service bulletin and recall for that actuator on certain year...

  2. Vibration issues on 2022 Bronco Sport Outer Banks

    I've had my BS since Dec 2024. Didn't have any issues until end of March beginning of April. I started to notice a vibration/shudder in the rear. It is intermittent, but happens every time I drive the car. I've taken it to Ford multiple times for this issue. Symptoms: Harsh shifting at times...

  3. Low speed shudder

    My '22 BS/OB developed a shudder at very low speed - less than 5 MPH, around 18K miles. Lived with it as I also had a bad RDU . RDU was replaced, shudder still there. Took to dealer for regular service, at 22K miles, so I paid for transmission fluid replacement. I don't drive much so I...

    Hello all, I purchased a used 2021 Bronco Sport Badlands with just under 40,000 miles on it a little over a year ago. During that time I have had a blast driving this car everydy and have had zero issues with the car besides the dreaded brake moan (whale sounds) that many of us have had. I...

  5. 2021 Bronco sport Big Bend rear diff speed sensor

    The dealership replaced my RDU. It was doing the same thing with the same potential remedies. The new RDU I've not had any problems.

  6. 2021 Bronco sport Big Bend rear diff speed sensor

    Not a band aid, and I’ve seen the new tsb as I stated above. The rdu is causing the shudder due to contaminated gear oil, idk why you’d think it’s on its way out? Do you understand how a rear diff works?

  7. 2021 Bronco sport Big Bend rear diff speed sensor

    Had a shudder while turning at low speeds in my 2021 Bronco sport big bend, I was also getting a “4wd fault” I scanned it and it was for the rear diff speed sensor . Took it to the dealer for the battery recall, while I was there asked the tech about the shudder. He took it for a ride, came back...

  8. Shudder on left turn...

    ...you can hear it and feel it, not so with a control arm, the CA would makes more of clunking noise, maybe vibrate at speed. In my case the RDU shudder was undeniable, especially when in reverse and turning out of a parking spot. If the shudder has been fixed with the CA change out I would be...

    Perhaps you are getting TSB 25-2351, probably worth calling the dealership to verify exactly whst they will be doing in those 4 hours. https://www.broncosportforum.com/forum/threads/new-tsb-25-2351-rdu-technical-service-bulletin-chatter-shudder-during-low-speed-turning-events.16807/

  10. Torque Converter Shudder Adventure

    Are you still under warranty? If so the torque and RDU are covered.

  11. Torque Converter Shudder Adventure

    This is complete BS!!! And I don’t mean Bronco Sport. They need to fix these issues. I now have the torque converter issue which I have to add shudder fix every 3-4 weeks and I am experiencing the grinding of RDU at low turn speeds. Why can’t they be honest and fix this. Still owe 20,000 on this...

  12. Shudder on left turn...

    So I took my 21 Bronco Sport Outerbanks in to Ford on Monday, they said it was not the RDU but they needed to replace the Left Lower control arm, they also changed the cabin filter and did brake fluid change. They said it would be ready Wednesday, they didn't call me until Thursday to pick it...

  14. Rear Differential Unit (RDU) Replacement

    @Agent084 .. you would need to go to a dealership before contacting Ford (should that contact be even necessary since you have the 100k warranty) smart idea to put on a set of ‘factory’ type tires and if you can take the RDU issue to a different dealership since one has already blamed an issue...
