Theres a rumbling noise when i let off of the accelerator in my truck?
I have a 2004 Chevy Blazer. I recently got the brakes fixed on it, I had a leak in a break line and they went out on me. About 10 minutes down the road from the shop I started hearing a rumbling noise. It started off as a high kinda humming noise and then got rougher and deeper as I went. It happens when I let off of the accelerator until I come to a complete stop. The humming usually starts when I hit around 40 mph or above and the rumbling starts when I let off the gas and just coast until I come to a complete stop. If it’s making the noise and I accelerate it gets quieter and closer to the humming again until I coast and the rumbling returns. https://photos.app.goo.gl/EU6nuksxsHQWwVyd8 The link above is to a video of the noise. It starts about 8 seconds in and gets considerably loud about half way through or so. Let me know if it doesn’t work. If you got any ideas as to what it is I’m all ears, thanks.
