I have an 04 2500 with tow package, 5.9 ho engine , my mirror is driving me nuts, is there any linkage or adjustment in the electric mirrors for this problem? if so ,... how? Tkanks in advance for your input!

foam...?

I have the manual fold out mirrors... no vibration. I know diesels vibrate more but is there another vibration making it worse... like tire balance. I don't know what else can be done... maybe put some stiff foam rubber in the housing to dampen it?
