Sorry if this is a double thread, i just realised where to post this and i cant seem to delete the other thread.

So i just picked 2013 XV CVT(in my country theres no more new Subaru,its dealer is closed here) like 2 months ago, i recently changed the wheel bearings, change cvt fluid, and change the control arm and such.

However i have this one problem, everytime i decelerate, theres like a 'whirring' or 'roaming' sound (i dont know which one to describe it), ive searched everywhere on subaru forum (forester,xv,and much more) and narrowed it down to a diff problem, a cvt problem, or drivetrain problems, do anyone know what caused this sound

if you cant hear it, please use headphone and u might hear it, its not that loud on the video though, but actually its quite noticeable. If you could try to hear the sound besides the engine sound

Hi @rizaldiiii.13 and welcome to the forums.

How many miles are on your new to you Crosstrek? Any info on service history?

I think I heard it.... Were the windows down when recording?

Hate to say it, but sounds CVT related....

thx for ur reply

its still on 30k miles, the previous owner rarely used it

the service history never mentions about cvt problems, but i think its been a while since the diff fluid is changed, and i think the tires pressure are needed to be checked, as for the cvt fluid i recently just changed it,the service history also never mentioned something anout cvt problems. i asked to my local XV forum and a Subaru Specialist Shop owner (not official from subaru) told me it might be a trans mount problem, as he had encounter it on a forester and it sounded pretty much the same, he told me to come to his shop but apperently i cant go there soon bcs of this pandemic, and i just want to get another opinion from anyone in this forum

nah, the windows are closed, i think its just my iphone x mic that are so bad that it records a lot of wind noise

and one last thing, will it become worse if i just ignore that sound?

Did it make that noise before you changed the CVT fluid?

Definitely transmission in that video...

So..... There are no Subaru dealers in your country anymore?

yea, since they got some tax problem here, and they cant afford the fine

so if i didnt change it soon enough, will it be a much bigger problem? bcs theres very limited sparepart here, and it would cost way too much to buy the entire trans from another country. i guess i could live with the noise, but im scared that someday it'll break eventually bcs of that noise problem

If your car is acting exactly as in the outback video then I would rule out the CVT.The only things in the CVT that can make noise are the chain and pulleys.When in neutral,the chain and pulleys will come to a stop and the noise will stop.The noise was unchanged when in neutral so the issue lies elsewhere.

ill give it a try then, changing it to neutral when coasting

yesterday i drove it on the highway and the sound kind of disappears though, i tried to recreate it and after a 30min drive it only happens like 3-4 times

Typically only 2 common source for that, cvt or differential. I think if the noise change when you put into neutral during coasting then it can be cvt, if it does not change then perhaps the differential issue. Did you hear the same sound when you accelerate or maintain the speed?

when i accelerating or just maintaining speed (foot slightly pressing throttle) i didnt hear it, actually i didnt really know though, is the sound so small that its barely noticeable or theres no sound at all

What oil did you use when you change the cvt and diff? For diff you may try to add mos2 additive to quieten

Well you can change the oil to make sure it is good or just open the inlet and try to sample to see of it looks ok. Just get GL5 oil to change.

Try to reach out to the person who posted the Outback video and see if and how it was resolved. He posted the video in October of last year so chances are it's been fixed. I think you're having the same problem he had.
