Strange Dragging Sound at Low Speed

[Vince Cantore]

Not sure if any other owners have experienced this concern. When driving at low speeds (less than 10 mph) I hear a sound as if something is dragging on the ground. I've checked the undercarriage of the truck and there is nothing obvious. I'm wondering if its a problem with the breaks/regenerative breaking. The sound seems to be coming from the driver side front wheel area. I don't notice the sound at higher speeds.

Does it sound like a chain? I had that. It was the axle bolt that had come loose. Service guy said mine wasn't the first one.

You sure it's not just the pedestrian warning system?

Can you share more details on this? Was it the CV shaft bolt in the center of the hub? Thanks...

Yes. They replaced the bolt and put more loctite on it. Said some were coming from the factory without an adequate amount of threadlocker.

It should be reverse threaded but they haven't done that for them yet.

Thanks for the response. Good to know this info.

This sound caught me by surprise too the first time. A weird dragging, air whooshing sound. Not like a weird Toyota spaceship sound, LOL

I wonder if we can find out the torque spec is on this bolt. I am guessing this is also the source of the creaking at slow speeds, when the splines move slightly.
