If the windows are up, not bad. Down, and there's a bit of flapping noise.I do love the Sunrider on my 2 Door, but it was noticeably louder when closed, have you noticed the same?
Managed to pick up a gently used one for cheep but it is noisy as hell lol, thanks for the write up I'll have to give it a go next time I have time off.Had some noise issues… figured I’d cross post in a couple more threads…
Success!!!
Got the sunrider quiet!!!
5 things:
1) Clean the whole seal perimeter of the bronco from dust and dirt. Alcohol and clean rag.
2) Replaced the 5.5mm plastic washers with 2mm thick ones (Amazon). Allows the back to sit better against the seal and back roof.
3) Pushed the whole assembly rearward and held there with a bit of pressure before bolting it down. Does two things. Better seal at back and also moves front hooks a bit back to better preload them when they latch closed against the metal loops.
4) There are rivets used in the front bracketry. Two per side But they are too long and hit the door header sheetmetal. I ground the tips down with a dremel down to the nail ball. Cleaned up the sharp edges. Then dusted them with spray paint.
As an extra step I cut rectangular pieces of bicycle inner tube and glued them over the rivet area on each side.
5) I got some weather strip - double D shaped one (Frost King 5/16 x 1/4). Attached that the front center metal brace to have a better seal against the secondary base seal bulb.
All the above did the trick! Tested at 70mph on the freeway even with this super windy day here - no more whistling! And overall it's not much louder than the stock panels.
