my truck was making a grinding/screeching sound and that ended up being the emergency brake had exploded into the right rear wheel....very weird...but got that fixed..

but my truck has also been making a rattling sound.
It doesn't always do it but when it does it's usually hot out and usually only just after i have started the truck...usually once i put it in reverse or drive the sound goes away but other times it will continue for a few seconds and then go away and it never comes back the whole time i am driving...
my ex thought maybe my heat shield was loose??


any suggestions as to what this could be?

 

what cab, and where is the noise coming from?

 

extended cab, noise is comming from somewhere within the bottom of the truck

 

get under it and bang on the exhaust

 

here is a clip so you can hear the sound..hope that helps..
it's comming from the front

 

Does the sound change with throttle input? Listening to the clip, whatever it is doesn't sound good. It sounds like exhaust but could be transmission. Have you checked the heat shield on the cats and muffler? It might be time for a nice new SIDO exhaust system.

 

no idea where the heat shield is even located. lol sorry not very mechanically literate
the sound goes away as soon as i give it any gas.
i need a new exhaust system anyhow cause mine is bent thanks to my brother..this could have something to do with the sound i guess ...?

 

duuudddeee that fat bend could definitely be choking your engine...very limited airflow....get a new exhaust IMMEDIATELY. If not, at least go saw off the pipe before that bend for now. Plus, it'll sound a ton better with an aftermarket muffler.

 

can you recommend a good exhaust that wont cost me a fortune?

 

dynomax race bullet. Its 40 bucks at www.summitracing.com and will sound incredible. Get the 2.5" in/out and 12" length. Installation for just a muffler replacement shouldnt be more than 40-50 bucks, so you'll spend less than 100 total and it will sound great.

 

okay probably sounds stupid but what does this do? do i just have the end cut off and replace it with this? there's an exhaust pro shop down the street from my house so i'm guessing they could do it all for me...

 

Yup, that bend could have a lot to do with it. The heat shields are located on the bottom of the cats and the muffler. They are large pieces of sheet metal that sit about 3/8" away from the components. Depending on how much $$$ you want to spend, you could have the exhaust shop price out a cat back SIDO setup with your choice of mufflers. I got mine installed from the cat all the way out the rear corners for under $350. I am running a Flowmaster 50 series. It is not too loud and it has no drone at all. I tow often and didn't want an aggravating drone at 2200 RPM's, thats why I went with the 50 series. I would at least hack the bend off with a sawzall or hack saw. It is not good for the motor to have that much restriction. It looks like it is almost sealed off!

 

The bent tail pipe does need immediate attention first off. The muffler and tail pipe are one piece so it would be a good time to get that monstrosity of a muffler off. But I don't know what your preferences is on how much noise you would like so be careful on what you pick. Also, I would start banging around the exhaust system and see if you can duplicate the noise. Maybe when the pipe was damaged ,it loosened up something else. But IMO. I would locate the noise before spending $ on an exhaust system. I used to love em loud, but now that I'm "getting up there in years" The quieter the better for me. Good luck on finding that noise, it doesn't sound good.

 

I don't want a really loud exhaust, just something with a bit of a rumble to it

 

That is why I went with the 50 series. Not loud, no drone, nice and mellow.
