Default Why are my heat shields on my 04 Honda Accord loose and vibrating?

So, I had all of my brake pads, rotors, and calipers replaced at Firestone. About a week ago this horrible rattling was coming from my front axle. I assumed they forgot to tighten something, so I brought it back in. They said it wasn't their fault, but to fix it, it would be $600, because of all the labor to get to the part! They said the screws were loose, so the plates were vibrating. They said it wouldn't damage anything if I drove it like that. It is soooooooooooo irritating though. Something needs to be done. It happens at 1.5-2.5rpm's. I just have to accelerate faster or let of the gas. I think the sound is getting worse too. Anywho, could the mechanics have loosened this part on purpose so I would come back, or is it just coincidence that it happened a week after I brought it in? Also, is there any way to tell? Oh, and is it really a $600 job?

The bolts that hold the heat shield in place are subject to corrosion. In time and with age they tend to develop a bit of free play. This is actually a bit harder to fix due to the corrosion. You can't just turn the bolt a bit tighter, it will in all likely hood break off rather than tighten. Some times you can finesse the noise away with a bit of stainless steel safety wire wrapped around the bolt just below the bolt head and twisted tight. This has worked for several of my customers and is relatively cheap to accomplish. It may just be the answer that you are looking for. I have tried in the past to tighten the bolts and even with heat and liquid wrench only one in five would tighten. Good Luck

Unbolt the heatshield...Throw it away as far as you can..Problem solved. OR Turn the music up on your stereo usually solves the problem.
