My truck has this incredibly annoying and embarrassing rattle at low rpms (1500-1900rpm) usually around 30-50kmh.

Sounds like it's one of the heat shields or skidplates, or might even be caused by the flange connection between the exhaust manifold and the exhaust near the transfer case.

Anyone else ever have this? I'm thinking of pulling all the heat shields and skidplates off and putting them back on one at a time to figure out where the rattle is coming from. Sounds like its coming from near the front, so could be the exhaust flange with the springs, or just a loose heat shield. It's so annoying.

 

lol the first embarrassing thing is its a Mazda lmao jk..

 

Get the biggest hose clamp you can find. Wrap it around the cat and tighten it down. Instant rattle fix.

 

Im not sure what it is but when i accelerate kinda hard my truck rattles i dont know if thats the timing chain or what

 

Works well on feline cats too.

 

Ya, I got the some kinda rattle and it is either my cat or the heat shield.

 

my heat shield got ripped off from 4 wheeling lol

 

Perhaps more wheeling shall solve my problem. LOL

 

Just rip off the shield yourself...?

 

lol, I had already mentioned I would take them all off and but them back on by one until the rattle comes back.

 

my truck rattles at low speeds too. and as i go faster it turns into a hum.

damn knobby tires.

 

it feels like im driving over one of these at low speeds


the cattle grate, not the cattle.

 

Turns out it's the heat shield on my muffler.

So on Thursday I'm getting a nice Flowmaster 40 series to replace it. w00t!
