alittleedgy Posted March 30, 2012 Report Share Posted March 30, 2012 Hello Ford Edge Owners.... First, I am more or less new to the forum and am finding this column to be the most active....if I need to post this elsewhere please let me know. But I have an '07 Edge that up until now has been more or less flawless. However, within the past two days I have noticed a rattle sound coming from somewhere under the car, approximately on the passenger side, sounds like near the front right wheel though I am not sure. Could be closer to the vicinity of the engine but definitively coming from somewhere under the car. I hear the sound upon acceleration, with the car moving, and its not consistent. If you were to put some bb's in a tin can and rapidly shake it, that is what it sounds like. Or, another way to describe it...if there were a very hard steel heat shield that was rapidly vibrating and impacting an adjacent structure. I've read on other sites on the 'net where other Ford models have had issues like this, and some folks claim it could be faulty ignition timing....or perhaps a catalytic converter that's been destroyed. However, I only hear the noise when the car is moving and upon acceleration. Any suggestions or diagnosis help would be appreciated. It has 76,XXX miles on it.

wlepse Posted March 30, 2012 Report Share Posted March 30, 2012 If it sounds like a rattle the first place I would look is the catalytic converter heat shield. 76k and a couple years of use might be a little early for it to let loose but not uncommon if you live in an area they use a lot of salt in the winter.

Hi alittleedgy and welcome. :D Blind Internet diagnosis? I would agree with wlepse...loose heat shield. However any decent mechanic could tell you in 5 minutes whether it is a loose heat shield, an engine issue or a catalytic converter problem. Keep us updated and good luck. :beerchug: Quote Link to comment Share on other sites More sharing options...
Scorpio Posted March 30, 2012 Report Share Posted March 30, 2012 Loose heat shield is a distinct possiblity, but "rattling BB's in a can" on acceleration is also one of the more common descriptions of engine pinging/detonation. That could be cause by a tank of bad gas, or is more common with cars with a few miles on 'em as carbon buildup in the combustion chamber increases octane requirement.

wlepse Posted March 30, 2012 Report Share Posted March 30, 2012 I would be surprised if it were pinging or a bad cat, both should come with a loss of power which wasn't mentioned. Either way I hope for the OP's sake it is just a heat shield. Quote Link to comment Share on other sites More sharing options...
Dingo Posted March 30, 2012 Report Share Posted March 30, 2012 Could be a bushing or a ball joint, too. Quote Link to comment Share on other sites More sharing options...
us11csalyer Posted March 31, 2012 Report Share Posted March 31, 2012 Could be a bushing or a ball joint, too. IDK about that. Back in my first car you could wiggle the front tires from needing new control arm busings, CV-joints moved, ect. No rattle from them. I did one time leave the heat shield on my starter loose and it rattled like the OP said. Quote Link to comment Share on other sites More sharing options...

Maybe send a PM (private message ) or post to FordGuru. who is a Ford mechanic. If anyone would have an inclination as to what the most possible problem would be, I would think that he would. IMO, sounds like a heat shield or pinging. Quote Link to comment Share on other sites More sharing options...
alittleedgy Posted March 31, 2012 Author Report Share Posted March 31, 2012 Havent had a chance to crawl under and or put it on jacks...but thanks all for the replies!! Ill follow up on your suggestions and let you all know. But even though sound travel is deceptive in cases like this in terms of easily finding the source ...I don't think its coming from the front drive mechanisms. On the other hand the weird part is that it happens while the car is moving. Quote Link to comment Share on other sites More sharing options...
alittleedgy Posted April 13, 2012 Author Report Share Posted April 13, 2012 Well, guess what..I was finally able put it on jacks and crawl around under there....I was looking for something kind of forward on the car...or mid-station.....because that is where the noise was coming from....I didn't find anything. I wiggled the exhaust system and tapped on heat shields...nothing.....then I happened to look aft and saw something hanging from the near the tail pipe....it was a busted band clamp that held a heat shield onto the pipe. It had snapped off and was just hanging there. One band clamp later and looks like situation solved! Thanks for your time! I was afraid of something really major...but this time the car gods were looking out for me! Thanks all for your time taken to reply and try to help!
