I have a 2017 Ecoboost that's currently at ~27,000 miles. Recently, I noticed that the rear right side of the car makes a creaking sound when making sharp turns at slow speeds. Sometimes, the noise occurs when driving on uneven (not bumpy) areas. I live in Durham where roads are kind of hilly. Majority of the times though, the sound occurs when making a sharp right turns like when pulling into the driveway. The sound is sort of like your typical bed creaking sound and seems to be coming from the right rear side of the car.
I took it to a well rated auto repair shop in the area and after their diagnosis, they said that it's because the mufflers and the muffler brackets which should be tightly coupled seem to have a bit of play between them due to which the noise is being produced. They applied lube to the brackets and said that that should take care of things. However, as soon as I drove off and approached my driveway, the sound was still there when making that sharp turn. So I spent $130 on nothing.
I took it back and they said that they'd probably have to replace the muffler brackets. However, I'm not entirely convinced by their diagnosis so I wanted to ask a few questions and get some advice here -
- Have you had a similar experience and how did you deal with it?
- Is their "play in the muffler bracket" diagnosis sound right to you?
- How can I actually get this properly diagnosis and fixed?
- How much would replacing muffler brackets cost?
- Is this a problem I can just ignore?
- Would taking the car to a Ford dealership be a better option instead? The car is past the 3 year warranty period, unfortunately.
Any other information and suggestions would be really helpful. Thanks.
