Seems like the OP on this thread had the same problem I'm having

I'm so happy:driving: I was able to find out where the rattling was coming from. Its coming from the passenger front dust shield behind the rotor. The dust shield taps against the rotor and caused the chatter. Can anyone tell me in which part of the service manual I can find how this dust shield is held on? I'm thinking either it got bent somehow or it lost a screw that was holding it in place. It's hard for me to tell since I did the inspection with the car on the ground.

The 2009 FSM shows the splash shield on page FAX-6. The splash shield is sandwiched between the steering knuckle and the wheel hub and bearing assembly.

Thanks Southark. Yes this is exactly what's rattling. It doesn't look like it could come off on its own so either it got bent or it cracked. I have no idea how this could have happened.

You're welcome.

It looks like the only way to remove it is to remove the hub/bearing ***'y. If it falls off, you have bigger problems than a splash shield. :)

My guess is that you ran over a limb, chunk of truck tire, or similar.

Going by the FSM, the hub/bearing looks similar to the setup on a mid-'90s Chevy FWD (minus the drive shaft) that a friend and I recently replaced. The job was amazingly easy once we got the right Torx wrench. If you have the proper tools, you can probably DIY.

So today I decided to put my car on ramps and find out if my splash guard was cracked or bent. It turns out that it was fine. It was actually a small rock that somehow had gotten in between the splash guard and the rotor and was rattling around in there. As I pulled the splash guard, the rock just fell. What I thought was gonna be a huge dis-assembly turned out to be a 5 min fix. :driving:

ive had a metallic flapping (around the passenger front area)for the last few weeks..nothing was loose. so i thought it was the dip stick tube hitting the header..after reading this thread i checked the dust shield but it was fine.. then i did find the lower shock bolt was loose so hoping thats the issue

heat shield got tweaked somehow

even though the dust shield doesnt look like its touching anywhere .i still have the noise... going to take the dust shield completely off and see what happens..

Is it anything like the noise I hear in mine?

no...yours sounds like a wheel bearing..... i found the bolts on my drive shaft cv were loose...i haven't put it on the ground yet but hopefully its fixed with adding lock washers

If you have adjusted anything in the front suspension, check the brake splash shields against the rotors too. If they get close, could be rattle too.

i took the passenger dust shield off ..im going to check the other side tomorrow

This is great everyone! Thanks for the help! I have this exact same rattle and it drives me nuts. If I go over a lane marker I hear it - this gives me hope, I am going to put the car up and see if I can take the wheel off and inspect all of the suggestions here. Thanks again!
