Squeaky Fiberglass Bedsides

I recently installed Fiberwerx Bedside fenders on my truck as im preparing to long travel the rear. Install was actually pretty easy, but towards the bottom of the fiberglass where it meets the cab (i believe this is where its coming from) its rubbing against my cab and making the most annoying squeaking noise. It almost sounds like a sound a mouse would make. Has anybody else had this problem and have an easy solution to fix it? Its an offroading truck so i can stand a little rattling here and there but this has to be the most annoying sound i have ever heard.

 

I just installed mine too and have it squeak in the same location. I am going to see how it is after I bolt it up in the front and see if it still does it when it is secure as its currently getting painted. I assume you already braced the front? Worst case, Im sure you could sand down some of the front contact points where it hits the cab as well.

Bro what happened to the avatar?

 

Yeah I figure sanding would be the best option. My fronts are not the problem at all. just the bedsides.

As far as the avatar goes, Pm me

 

Oh ok I meant from the front portion of the bedsides. Did you drill out a few holes on the front of the bed so that you will likely have to shift the bed to install bolts there?

 

Ah I see what youre saying. My bad. No I didn't but that would probably help

 

I would recommend that or else the wind will be able to shift it just enough for it to move about as it doesn't need much vibration to make a noise.
