Noisy on smooth roads.
It's just an annoying "ruuuuung" that's gotten louder and louder, and I can't seem to figure out what the problem is. I want to replace the tires, but it seems like a waste considering there's maybe 50-60% tread left of even wear.
I currently run a set of Falken ZIEX ZE-912 245/45/17 tires on a 2003 E500 sport.
At times I feel like the noise is coming from the front driver side generally towards the wheel. However, at times it feels like its coming from the front of the engine. I've checked the symptoms when the ball joint goes bad, but it's not a squeak over bumps. The noise generally occurs or becomes noticeable traveling on smooth tarmac at around 50mph+ around 2k-3.5k rpm until it becomes less noticeable.
