SOURCE: 03 Mountaineer AWD Premier V8 rattling noise under vehicle

If its the heat shield against the underside.its install with fender style aluminum rivets( if you do it be very careful not to drill into a harness) If its the heat shield around the CAT then you should replace the cat. You can try to repair it with a pair of long hose clamps but I don't advise removing it. In the wrong environment the heat could cause a grass fire. or ignite trash that may get caught or blown underneath. Good luck.

SOURCE: Accelarating from 25 to 40 MPH - a "rattle" in exhaust system

Had my y-pipe replaced (bad cats) and the bolts at the y-pipe flange where it attaches to the exhaust manifolds started to get loose and I go tthe viberating (tinning) noise. Took it in the first time and they tightened everything up but it seems it's doing it again so I'm going to try to fix on my own. Just wondering how much of a pain it's going to be to get to the bolts and what size...

SOURCE: My 2005 Corolla XRS has rattling when deaccelerating

I wouldn't say it is common. There are quite a few heat shields around the stock exhaust "header" and exhaust system. There are also FOUR motor mounts that you can check to see if all bolts are tight. They are all 14mm heads on the motor mounts, 12mm on the exhaust shields. These seem to be the main things that may get loose or make a rattling sound. The exhaust gasket is also designed to flex when the engine flexes - I would check into the exhaust. You have to remove the TRD strut bar to gain better access from above.

Can I remove heat shield on ford focus 2005 ??


I thin its better if you tihgten it bac up so that your car floor will not get hot and increase the temperature inside your vehicle. Not good especialy in the summer time.

A rattling nose when hitting rough roads and rr crossings


could be a loose heat shield on the exhaust or motor. could also be a problem with the struts but with a vehicle that new most likely just a loose heat shield.

My 2005 Nissan Morano S makes a rattling noise when accelerating. More so after the car has been sitting. Less after I driven awhile.Taken it in 3 times and no one is able to diagnose.


Hello Lisa,
Rattles are always a fun thing to chase after. The first thing that comes to mind with a rattle under acceleration would be a heat sheild. Over time, heat shields which protect the under body of the car from exhaust heat come loose. Might want to have an exhaust shop take a look at it for you. I have heard of weak tack welds located on the heat sheilds by the catalytic converter. So you can ask an exhaust shop to take a look.

Although if you are one to get down under the car and a bit dirty check it out on your own. You might be able to check without putting the truck on a jack stands or a lift. Basically you will want to ensure the car is cold. If the car has not sit for a little while, I would not recommend touching the exhaust. YOU WILL get burned. :) Once your sure its cold and want to squeeze under the truck you can follow the exhaust tips all the way up to the catalytic converters. See pic below(number 16 is the heat shield). You will see the tin around them and be able to shake them a bit. If you hear your rattle there is your problem. If not check out the other heat shields.

My Cady has developed a rattling noise under that increases when I accelated


A common cause for the "rattling" noise you've described is a loose heat shield for the catalytic converter. Many times, a weld will break loose leaving you with a hanging heat shield that vibrates and "rattles" while you drive. A trip to the muffler shop should be able to confirm this. By itself, a loose heat shield is not something major.

Another cause could be a loose exhaust hanger that holds the exhaust firmly in place. It too would tend to rattle more as you drive. Either way, it would appear on the surface that your issue is exhaust related. Best of luck and thank you for using Fixya!

When you push on the gas it rattles something near


Usually this type concern is a exhaust heat shield loose or damaged or components inside the exhaust system damaged or a faulty motor/transaxle mount.
