Small thud when beginning to roll

[BigfootArea51]

It depends on where the wheels are in rotation that I feel it but from a stop when releasing the brake I’m feeling a small thud when starting to roll. I only feel it then but after in motion not noticing anything also no audible sounds. What can this be anyone else experience this?

Hey there. I can look into your Bronco’s concerns on my end if you’d like. Will you send us a private message with your VIN and dealership info?

I'd like to know what this is as well. The first time it occurred for me, I was sure that the bus behind me bumped me. That's what it feels like. I looked closely to see if there was any scuff marks on the spare tire. It has since happened several times.

‘how long has yours been doing this. For me it’s a quick double thud then when I’m rolling it’s fine.

Is it almost like the rear struts are getting unstuck??

 

[BigfootArea51]

Not sure. But it definitely depend on the position of the wheels. I can let go of the brake nothing. move up a little stop, then let go of the brake and it does it.

Slack from driveshaft...

I think it’s just sticky brakes, depending on weather conditions, too, like humidity.

It’s just driveline lash. These things have very flexible capabilities throughout the suspension. U joints, etc. a little rebound from a stop is expected

My Ranger had done this once in the last year. For now, not concerned.

At odd times... I haven't been able to pin down an exact moment. It's usually when I'm stopped at a Traffic light. I may be creeping up, not sure. It's a noticeable 'bump' like someone just nudged the Bronco somewhere. A quick check of the 360 camera and I can tell that no one is that close.

What do you have against a small thud?

 

[ChrisB351]

Mine does it occasionally. Sounds like a slip yoke but to my understand we dont have those. They do have a 2pc driveshaft so I assume its probably in there. Ive seen so many comments and its not often or major enough that Im worried.. just a characteristic of the vehicle.

Maybe by design to make the 6Gs more like the early Broncos. Every EB that I've owned had the Bronco clunk from the slip yoke...

I have been experiencing something similar as well. It's almost as if something is loading and unloading in the drivetrain during load speed stop and go. A definitive clunk/catch/bump like occurrence.

Backlash is NOT a good thing in geared/rotational parts - so I really hope it's not .

Can't tell if it's transmission, driveshaft, differential, or brakes. Need to get under the bronco and see if there is any slop I can identify.
