Rattling Noise on Car near the Foot Pedal

Since very end of last trip to Redwoods National Park/Oregon Coast, I felt some metal is clicking when vehicle’s speed is increased, but immediately disappear after the speed is up and more painfully irregularly.

So much of our freak-o-meter went up, the unlimited search on youtube was on. Metal Noise (when speed is up), Metal scratching when speed is increasted etc.. , then every different ones were suggesting break pad problem, transmission problem etc,.

Data science kicked in with extremely mental hypothesis testing ‘Does it make noise when it is uphill or downhill’, ‘Does it make noise when road surface is not bumpy or not’, then one great clue I landed was ‘It always sounds at 20MPH -40MPH. However, that theory was broken when I was testing on freeway it made a noise again around 60 MPH as well. Ah…

At the end of lengthy period of hypothesis testing, came to conclusion this mostly happens when RPM is passing thru 2,000-2,500 and less in the morning; especially when engine works one more step. Then I searched the web and youtube to learn this is more likely the problem of heat reflection metals around the exhaust system getting aging and loose and the vibration from the engine is making it “rattle” – glad it was not a break nor transmission problem ๐Ÿ™‚

Went to auto repair shop, and the mechanic simply screwed in one screw piece in the gap at the surrounding cover parts near the engine (Catalyst) and it was fine. His suggestion was using this as molding is the ultimate solution but it will be costly and time consuming ๐Ÿ™‚

However, that patch didn’t last long, and about a week later started to hear the rattling again. So decided to go more permanent solution.

So crazy DIY kicked in –

Ordered a ‘ramp’ as I don’t have the jack (and I have been in the need of something to put my car up for other reasons)

Looked at the area where the screw-patch was on – clearly gone ๐Ÿ˜ฆ

So followed one of the videos suggesting using the metal clamp to hold the covering tight – some suggested zips but clearly got to know that won’t last at here as it was extremely hot with simple driving.

At the end, when the ramp and metal round clamp arrived, put the car on the ramp, dig thru under the car (first time using the back to move around after highschool’s military training class) put two clamps with painful arms with the hope at least one will resolve.

At the end – perfect solution. The rattle is gone now, (although hurt my eyes as particle dust from the car hit my right eye; continuously pumping tears for few hours. (+ countless attempt to wash out with tons of water :))
