The noise could be coming from front diff, this is how things sounded when I had bad transfer case bearings:

I can assure you that mechanic is clueless to what's causing that noise if he thinks those 2 things could be causing that noise.

that's tranny rattle noise.

perfectly normal, and due to gear lash.

adding aftermarket exhaust without changing the downpipe could effect the fitment and create rattling, especially as air escapes through the exhaust. but i'm a newb.

if that's the tranny rattling then he should hear it when revving in neutral. Or at least hear something

ummm.

you are misunderstanding the rattle.

the engine must be compression braking in order for the gear lash to chatter.

it's EXACTLY the same as "lightweight flywheel decel" noise, just a little less loud.

okay so you say it's "tranny rattle noise" but what is tranny rattle noise, you say it's normal but my car/tranny doesn't make that sound. I'm just trying to understand what your saying it is bc I have never heard that before and I really doubt it's normal

^^^^I think he is referring to gear "whine"

Check your up pipe heat shield, seriously, mine made the same noise and i pulled my hair out for 2 weeks trying to find the cause. Turns out the spot welds failed and allowed the heat shield to move around when engine braking.

that is not gear whine. If it is then that gear box is about to explode bc that would be the loudest gear whine I ever heard lol

My LGT came from the factory with a dual mass flywheel. I switched to a lightweight single mass flywheel from a wrx. My car on decel sounded exactly like the car in the video, but a bit louder.

A bit of crunchy noise, a bit of kurkurkur mixed together.

so then maybe he needs to have his flywheel machined and some new bearings. Maybe that will help

ive never experienced tranny noises like that in any of my subarus. If my tranny ever sounded like that I would replace it. That's just me

if I were you I would find a reputable shop that is good with subaru's, or even better one that specializes with subaru's. Take it to them and see what they say. That's what I would do

I took it to the shop already and they told me its either shaft play or loose cat. just wondered if anyone here encountered something like that. I don't want to pay like $200 for them just to take my downpipe out and see if there's shaftplay

The only way to "fix" it is to put on a heavier flywheel.

As fhi did between my02 and my03 wrxs...

but if you insist on parting with your money on a witch hunt, I'm certain the shop will be more than happy to take it.

you didn't take it to a shop you took it to a dealership. That tried telling you the noise is shaft play in the turbo...dude if your turbo was making all that noise it wouldn't make it 15ft down the road. Just bc the dealership told you something doesn't mean they have the slightest clue what they're talking about or have any idea on modifications of subarus and building and all that. I'm saying to take it to a real shop that builds these cars, they should be able to help you.

or do what ride is saying and replace the flywheel. I wouldn't pay the people that told you it's shaft play to replace your flywheel though

Sounds like the normal sound of gears inside the tranny. Do a trans and diff flush first cheapest way to find out and plus looks like your overdue for one since you havent changed it.make sure you put the correct amount of fluid. GL

i do not believe there is a bolt on heavier flywheel option available.

the comment was tongue in cheek.

my car is about 4x louder due to the act streetlite i put on when i changed my clutc h the first time, ~7 years ago. 02s and some early 03s had light(er) weight flys right out of the factory. when fhi got complaints, they issued a TSB which replaced the flys in those cars with a heavier one (along with a couple of other associated changes like TOB, etc).

a flud change can dampen the sound somewhat. as i said, the issue is due to the great number of gears and diffs inside the tranny, each mesh point having a tiny amount of lash or play. the issue only occurs on decel, in gear, with clutch out, and is most noticable when engine braking is strongest (ie lower gears).

but hey, i've only been here over a decade with ~100k miles on my car, so take it fwiw.

Change you fluid for a start kid its the cheapest way . Plus your overdue anyway. Observe the fluid for chips and fillings from the gears. As ride5000 said
