Has anyone come up with an improvement? Would a smaller mirror work better? I've checked and they are mounted tight to the door and the mirrors tight to the arms. Thanks Kevin
Thanks, keep truckin!

I'd try the round ones and see if that makes a difference. If not, you might have something loose under the cab sending a vibration up and the mirrors are vibrating in sympathy.

I replaced my U-joints one day and for the heck of it had the drive shaft balanced. My mirror stopped vibrating after that.
Also, one day I started up my freshly rebuilt 270, the mechanic and I checked everything over and I was about to back out of his shop and take it on its maiden voyage. As I looked in the rear view mirror I noticed a barely perceptible intermittent blur. It couldn't be heard or felt, but you could see it in the mirror. Long story short; the engine was bad and I have a new mechanic.
The point is; the slightest vibration in the engine, drive shaft, wheels/tires, etc. is exaggerated in a mirror because you're not looking at the mirror you're looking at a point sometimes half a mile away. | | | | | Joined: Feb 2015 Posts: 33 Wrench Fetcher | | Wrench Fetcher Joined: Feb 2015 Posts: 33 | Thanks guys, I think I will go to the smaller mirrors as an option, I have not done any improvements underneath so that seems to have an effect. Thanks
