Vibration

[DIESEL/VETTE]

I am starting to see a very fine vibration in my rear view mirror, enough to where it's not clear, and i can barly feel it in my steering wheel. Only when stopped not under way. Any idea's 2003 2500 hd duramax.

It's a 17 y/o truck, no reason to not suspect normal stuff first. Engine/tranny mounts, exhaust plumbing and hardware, intake plumbing, or a combination of any of them. The rubber isolators are certainly less soft than when new. Also check the mirror, which can also loosen over time.
