1998 C230, 250K, many squeaks
 

My C230 is nearing 250K miles and 15 years.

Several squeaks have been around and I need to stomp out some of them.

One only occurs in the morning for about the first 1/4 mile and sounds just like a bad speedo cable, is speed dependent, and comes from the passenger footwell area. But does this car even have a speedo cable? I thought it was electronic.

Another squeak has been there for probably 7 years. It sounds like a cricket in the dash and only occurs when I turn left. I have presumed that is a fan bearing somewhere, but which one?

A new one happens sometimes when I turn the wheel at slow or no speed. It comes from the front right. I changed the lower ball joints about 5 years ago. Could it be the uppers? Idler arm?

It is hard to troubleshoot these since they are intermittant.

Thanks

Call me on this one.

You are fighting what is called "NVH" = Noise Vibration Harshness.
Noise, Vibration and Harshness (NVH) - SAE Automotive Standards

I have advice and suggestions.
