Hate to ask but have a rattle..... - Toyota GR86, 86, FR-S and Subaru BRZ Forum & Owners Community

Ok I have searched rattles and there are a lot to weed threw. Asking it here because a lot of you are quick to respond. I have a rattle and I only hear it at highway speeds. 70mph plus. It sounds like it's coming from the right rear area. I can't pin point it because I rarely have a passenger to track it down. It sounds like it's more of a flapping wind kinda noise and not a vibration rattle.

Can anybody narrow it down. Again sounds like, from the drivers seat, it's coming from the outside right rear of the car.... But not 100% sure.

Under pannel plastic?

Mr.ac · 08-01-2016, 09:19 PM

From what you describe, it could be the fender liners, or one of the underbody liners.
You'll have to jack the car up and do some wiggling, maybe a few fasteners came lose. Or broke off.

Low tire on that side?

jimmillion · 08-02-2016, 09:31 AM

If it's the left trunk side as in the passenger side and the rattle sound like plastic rattling at highway speeds then it could be what I encountered.

After I installed my rally armor mud guards, they would flap at highway speeds and cause my rear bumper to giggle and create a plastic clicking/ rattling sound in the rear left. Took me quite a while to isolate and stop it, but I did it by removing the whole bumper and sliding in rubber washers over all the pop-in clips.

To test my theory I duct taped up the seams of my bumper drove it on the highway to confirm it before committing to fully disassembling my rear bumper.

Its been quiet for a few months now so hopefully that helps you.

you driving with the windows down? i had the rear seat belt flapping against the rear plastic panel from the wind blowing in

Do you have mudguards on yours? I had to retighten the screws after awhile, because the dealer install wasn't up to snuff.

your car's totaled. Time to buy a 2017.

I would check the wheel liner's in the rear and the panels towards the back of the car.

Does it sound liek its charging up?

I think it may be the rear passenger side bumper. If I push the top edge of the bumper close to the fender. I get about an 8th of an inch of movement. Like the poppet is not holding it snugly. I also get a rattle type noise if I wiggle it fast enough.

Once you've fix this rattle, another one ALWAYS appears.

I've spent wayy too much time in the past fixing rattles and they always come back.

Embrace the rattles like other 86 owners embrace the crickets.
