I have a noise it sounds like something flapping in the wind almost or like a rock stuck in tire tread. It varies with speed but not with engine RPM. Almost can''t hear it unless your driving along a fence or a underpass where the noise echos back into the car. I jacked up the car to look under it, and inspect the tire tread. No rocks in the tires. Nothing hanging that would be flapping that I see( stuck plastic bag, or a loose plastic panel). Checked the CV boots to make sure they looked in good shape and weren't torn. Car is an 05 Scion tC with about 78K on it. Everything else works great. I first noticed this noise after driving down a loose gravel driveway which made me think of a rock in the tire but that was a couple weeks ago and the noise is still there. Any ideas?
Re: tC makes a ticking / flapping noise when driving.
Our XA had been in several times to try to find the noise and no one could figure it out. We also thought it sounded like a rock in tread or like baseball cards strapped to your bike frame to hit the spokes when you were little. I did lots of research yesterday and one guy said to remove wheel cover and see if it stops. It did. Turns out there was a broken clip that holds the wheel cover on. It was bent over and able to catch air and make noise. We snapped it off and replace wheel cover tightly and no more noise. I kind of laughed when I first read the solution and said the same thing---could it be that simple? He also said that sometimes the center decorative "scion" logo that covers the Toyota one in the middle of wheel cover can come loose and do the same thing

If your car is running fine and only making a noise when you are traveling at high speed it may be wind related. Check inside your front wheel wells behind the tires... There should be a rubber sheet between there and the engine compartment. It's designed to protect components on your engine from rain water & road debris etc. Make sure it's hanging down straight and not caught up on anything or torn. If that's not it, look around in your engine compartment and undercarriage for anything loose that would flap around in the wind (i.e. a mechanic's rag, tool or something got stuck you ran over). If you don't see anything out of the norm you can try a blower directed at your car to mimic wind conditions at 60 mph. The noise may present itself to a degree. It might be a long shot but worth a try. Good luck with you mystery noise. Let us know how it turns out.
Take the car to a trusted tire store and have them dismount the tire on that wheel to look for an embedded rock or metal piece in the tread area. It may not show itself from the outside due to lack of weight on the area of interest, but an internal inspection may show it up. Try putting the spare wheel on to see if the sound goes away. Hope this helps!
possibly a cv joint is going or perhaps a wheel bearing. any other symptoms ? in a parking lot turn the wheel all the way to the right and drive slowly in a circle and listen for a clicking sound... then turn it to the left and repeat. make sure it's an empty parking lot and you don't hit anything.
My first thought is a rock hung in the tire but surely you have checked for that? If you only hear it as the tire turns and it get faster as the tire tire turns faster then it has to be either the tire, brakes, or wheel bearing. Remove the wheel and throughly inspect everything. Look for a rock or some other object stuck in the tire or the brake system. You may have to remove the pads to find it. Inspect the brake slide pins and lubricate them with brake grease. Clean all rust and corrosion from the brake components with a wire brush and brake cleaner.
I had the same sound that you mentioned. I found it to be the roof rack sliding backwards. Tightened it and the noise went away. Occasionally, it will make the same noise, depending on the wind, but I have always found it to be stopped by tightening the roof rack. Hope this helps.
1 : An axle joint clicking away (which would probably be under warranty anyways) 2 : A bearing can click like this when first starting to let go (some bearings don't last 5,000 miles when new due to flaws) 3 : Imperfection on the tire, causing a ticking like sound when a certain spot is hitting pavement. 4 : It could even be as simple as a brake bad vibrating which I've seen a few times!
