Motor Mount Crossbolt
Installed Brown Dog motor mounts over the weekend. After install I tightened the cross bolt pretty tight. Afterwards I had vibrations when driving. I loosened the cross bolt up and vibes decreased.

Question is how loose is still ok for the cross bolt. I was thinking of loosening it more to see if I can eliminate vibes but don't know if there is a risk with going too loose?

Assuming you used the mounts only, and not their brackets? That's what I did last year, and had the same question. I called Browndog, his suggestion was to only tighten them up until you can no longer move the washers by hand. It's a lock-nut of sorts, so it will stay where you put it. Too tight=vibes
Too loose= vibes and motor shimmy

I didn't have any washers when I pulled and replaced. I guess I can just loosen them until there snug and the bolt wont turn by hand??

I'm installing these as soon as they get delivered, I ordered the rubber ones and the whole brkt/mount. Is that what you used?
