I just noticed this the other day on my wifes car. It poured over the weekend, of course, and when i went through some puddles there would be a groan coming from the front right. It would last about 20 seconds until I went through another puddle. Any idea what this could be? I was thinking water getting a cv joint, if there is one on the front of the car. I have yet to crawl under this car since getting it in December so I don't know what the front suspension looks like. ????? Actually i did crawl under to change the oil and realized the cannister was on the top.
