Creaking noise from suspension
Lately, my car's been making this creaking noise as the suspension travels. I took the car to the dealership and they told me that because I lowered the car I've caused the noise. Then they told me that I need new upper control arms in front, and need more time to diagnose what needs to be done to the rear to cure the noise.
Normally I would believe what they're saying, but this is the same dealership that once blamed a misfire in my engine to my remus exhaust and not the real problem which was a bad seal around the spark plug firing on the 4th cylinder.
Any thoughts on what the real sourse of these creaking noises might be?
