I noticed this last night while on my way home from picking my truck up after a leveling kit was installed.

If I am coasting the truck sounds normal. No rattle can be heard. If I accelerate or hold the throttle open slightly I hear a rattle that SOUNDS like it's coming from the front passenger side. It's too faint to get on video, I've tried. And it's more pronounced when the sound is bouncing off something to my right side (a house, another car, a fence, etc). Any ideas what it could be. I know my heat shield could be loose as they did work on my cats back in January.

 

That was going to be my suggestion.

 

The issue for me is that the rattle stops immediately when I take my foot off the gas.

 

Which is common. The added energy of a higher engine speed makes the shield rattle, then it calms down when you tell the engine to relax.

 

Hmmmm.... I'll take a look today, then.

 

Get a recording if you can. That'll really help.

 

Any way to attach a recording from the mobile app?

 

Please tell me it's not a hub actuator or some bull****.


I found my sway bar link is not attached to the sway bar, but that wouldn't make this sound, correct?

 

Damn.... still tough to hear. I may have the wife record it again.

 

Cant hear anything in the video.

I would start with the sway bar link that wasn't connected. Other than that, wait until everything and cold and get under and start rattling stuff around. You should be able to find something loose.
