When i get on the highway for about the first mile i hear this flapping noise and another low screeching type noise from passenger side. Then it goes away. It started about a month ago. Anyone think they might know what it is?

 

it could be a small animal

define screeching noise, might be a bearing but that should be constantly making a horrible noise.

Have someone drive the car by your house and see if you can locate anything more specific.

check your fender liner, might be cracked or there might be something stuck under your car.

 

My guess is that something's stuck under the car...

Since you're in Texas, check for dead Messicans, lol.

JCON might be on to something. The fender liners are two pieces, the fast moving air might be catching a loose spot and be pulling it toward the tire. The liners are only held in place plastic clips, one or two could have broken and/or fallen out.

Let us know what you find out.

 

alright im going to check under the car and what not. Hopefully no mexican...lol
