Roof bolts... creaks/cracks/...

[Harvey]

Well!!!! Thanks Guys! My problem seems solved by a simple 1/8 turn on each five of the screws. More test driving will come, but I did a reasonable test drive after the fix and didn't produce the sound once!!! So hopefully that's it for now. I'm happy, because it was a shame, a part from that I found the car sounded rather smooth, sturdy and solid. So now it does sound smooth and solid (I happen to have no other rattles ... yet).


However a few comments/questions all the same.... just how tight are these screws meant to be? I mean mine were pretty loose, two of them could be unscrewed with the socket and without the wrench, trying hard I could have undone one by hand I'd say. They were all five "just loose", I mean I put 1/8 a turn (1/4 at most) really easy and they then felt locked and it would have required great effort to get another 1/8 on them? Looks like they were kind of put in place (hand tight) but not really tightened (robot was tired)... I'm thinking of posting an email to Toyota to ask them the specification torque on these and tell them how mine were.


In all cases, thanks, the forum information gave me the conviction (and details about how to get to them) to go for it and I'm pleased I did rather than leaving it at the dealer (where their main plan/threat was to keep it 3 or 4 days, tear it appart, try to locate the problem, pray they find it and can fix it, and hope that no new rattles would appear after putting it back together.... knowing they were convinced it was more like "exhaust/underneath related" ....)

I don't think they're supposed to be loose at all really. Certainly not finger turnable. Paranoid now and thinking I should check mine to see if any of creaks are from that.

If you do I'd be curious to know how tight/loose they are...


Makes me think of RC model stuff which is "pre assembled" and it's up to the owner to finalise the build and "check all the scews".... in fact our GT86s are in fact pre built!

A long screwdriver, or any long, solid rod can be used as a stethoscope.

Used this many many times to find where noises were coming from.

I have the same problem on the new 16 brz.
The dealer tried to fix in their own way by loose the metal part with a flat head screwdriver.
However the rattle happens still several times during a drive, and also the roof can seen a little deformed from exterior almost on a 0.5 cm areas, although it can only be seen under the strong light in a dark place, but that really irks me. I will not believe there sincerity to fixing the rattle issues.

Is there any chance you know the size/model of tools I should use to tighten these 5 bolts ?

Merci d'avance.

what size of wrench/tool should I use to tighten these bolts ?
Is there any guide to remove the roof interior cover and trim ?

Thanks!

I had a similar sound coming from the roof area. Turned out it was actually the passenger seat vibrating. I reclined it a bit, declined it back and now it's quiet. Weird.
