Update: I can't believe how clean my doors and rear quarters are now with these. Usually the lower part of my driver door and rear quarters turn gray pretty fast. That and less stones clunking my steps.
That's what mine sounded like too, it was obnoxious 😂. Did it on mildly bumpy roads and on the highway, like the truck was purposefully testing my patience ☠️.
Finally installed these and am super happy with them. I wish I had them from day one! These are the OG/normal sized flaps. Initially was worried that they might look a little too big with the stock tires, but I think they look great.
I haven't heard that sound yet. It might be worth checking your front skid plate & side step bolts to make sure nothing is loose. It almost sounds suspension-ish.
Did you end up figuring this out? I found a huge gouge in my ranger raptors shifter on delivery. Sadly I agreed to a mobile repair instead of replacement. It looks fine but you can tell up close that it was ground/sprayed.
There are a few leather "covers" on ebay for the shifter. If mine ever...
Thanks to Topher & John for mentioning this. I had the exact same squeak sound and finally made time to troubleshoot. It was the rivnut/nutsert closest to the door that was loose in the sheet metal.
Went to the hardware store to make a cheap "tool" (6mm x 1 bolt, nut, & washer) and finished...
