Nowhere have I found any particular instructions on how tight, or loose, these 6 bolts should be to allow the rubber pads to absorb vibrations, but not so loose as to cause any negative consequences. I'm looking for feedback of your experiences on how you have dealt with this issue. Also any other ideas on how the quiet body vibrations would be welcome.

All parts are new in the mounts. I had the 6 bolts snugged down initially. Probably to the point where the tubular collars were not allowing for any movement.



There should be some metal spacers (A-5093) that control the proper spacing for you. Just tighten the nuts and key them and you will be set.
