My roof hatch has developed a rattle at the hinge at speeds over 50MPH. I've confirmed this is the rattle site, and it largely seems to be due to some play in the hinge pin. It goes away with some upward pressure from inside and the noise can be replicated when stopped.
I can imagine several possible solutions, but I'm wondering: Has anyone else faced and fixed this issue, and want to share their fix?
Better to build on the success of others when possible.
Hatch rattle fix?
Re: Hatch rattle fix?
I had a similar rattle but found it was due to an old stretched out rubber strap. The new one was about 2 inches shorter and after install, fixed the rattle.

Re: Hatch rattle fix?
Mine has a nice new strap, and the rattle's confirmed in the hinge area. I see springs in my future....
Thanks.
Thanks.

Re: Hatch rattle fix?
I've done the following which has addressed both the small bit of play in the hinge as well as some air entry (whistling) at highway speeds:ChickenPinz wrote: ↑Sun Mar 07, 2021 7:48 pm My roof hatch has developed a rattle at the hinge at speeds over 50MPH.

- Replaced the rubber retaining strap with a velcro strap that allows for tightening to your determination
- Added weather strip on the inside of the hatch that meets the lip of the port in the roof and take's up any gap that may be allowed by the play in the hinge
- Added pinch weld bulb weather seal to the outter lip of the hatch to prevent lift forces at highway speeds

Re: Hatch rattle fix?
The weatherstripping idea is a good one as the normal seal is a pretty high durometer.

Re: Hatch rattle fix?
Upon further inspection, the hinge pin is adjustable to set the vertical position. Loosen two 13mm head bolts, press down, tighten, fixed.ChickenPinz wrote: ↑Sun Mar 07, 2021 7:48 pm My roof hatch has developed a rattle at the hinge at speeds over 50MPH.
