Grinding sound

[madmikeismad]

auxillary brackets? On what?

 

[JariV]

Alternator bracket, power steering pump bracket, aircond bracket. Like those.

Or if you have a BHAF at the end of a long tube then it might connect with the body. Or intercooler tubes rubbing the frame. Or exhaust touching the frame. Things like this.

Ohh, gotcha. Added to the list of things to check. Thanks.

can you post a video of it making the noise?

It's not loud enough to hear with a camera I don't think. I only noticed it the first time because I could feel it through the truck. Not just the floorboards, but the seats and steering wheel too. Just a vibration. Then I turned the stereo off and listened, and it's a very very low grinding/vibration sound. And only at exactly 1000rpm.

Under the hood, you can tell the difference in tone from the motor, but it's really hard to get it at the right rpm to hear it or feel it.

I'll try to get a video though.

it may help. I was thinking it was a louder grinding noise

Yeah, I worded it bad. It's more of a very light vibration, but at times I'd swear it was something rubbing/grinding very lightly.
