Rear Fender Rattle

I've recently noticed a rattling sound coming from the passenger bedside when I close the passenger door or grab the fender flare and shake.

This didn't start until recently, so I think we can rule out anything manufacturing wise, unless someone forgot to put loctite on something. I'm the original owner and the truck has never been crashed or had body damage

I'm going to try to pull things and look around, but figured that I might be worthwhile to ask around to see if anyone else has run into this issue and knows where to start looking aroind.

 

my bet is it's the plastic wheel well liner against the frame or bed. Mine does the same

 

Check the plastic tabs on the top of the fender well liner, mine were worn out and I recently replaced them.

 

same issue with my truck.. Toyota checked it out and said nothing is loose! And the Passenger side window whistles like crazy at high speed

 

Same here. Toyota has no solution. Told me to turn my radio up

 

Rear wheelwell plastic liner , the push clips get loose after miles and years , i just bought 6 new ones today , gonna replace them this weekend . Pretty common .

 

Any chance you have the part number or link where you purchased them?
