    Well, looks like you've double checked the hell out of this one, maybe try tightening it down as even as possible and see how it goes?

    Torques down just fine; flattens out as it compresses the rubber. I called a dealership & talked to an experienced mechanic. He said it's as designed, at least every one he's done has been that way. I just hate it when there's something I can't find written anywhere though. No where in any manual is it mentioned. Hell, the old ones were the same and they seem fine after 23 years. Must be OK... LOL. I'm just too anal sometimes I guess. I'm pretty slow at this shit because I just sit and look at stuff and try and figure out the engineering behind it before I continue...

    On the plus side, being picky can keep you from making some expensive mistakes. You aren't working flat rate to my knowledge, so take your time.

    I just put new "clam shell" mounts like yours on my truck and had the same issue. I just got each bolt started on as many threads as I could (after some applied force) and zipped the bolts the rest of the way with my cordless impact. I think it's just a structural design and has something to do with the steel body of the mount. Mine turned out just fine and made a huge different from the mounts that were original from '98.

    That's interesting, I was easily able to get all the nuts started with no force needed... Anyways, it does appear to be the way it's supposed to be.
