Broken Motor Mounts

[NGAneer]

I thought I would post this vid I made of my Engine mount doing its thing...or not doing its thing I should say.

Have some strange random drive line clunks during shifts and I think this is the cause.

Looks broke to me. Mine moved a little bit more but it had bent the steel bar inside the mount that held the two halves together.

yep, that mount is toast.
At this point there would be no way I'd go with the OEM mount. replace it once with the Hummer mount and forget about it.

So if I want to replace both drivers side and passenger side mounts go with (25847739) hummer H3 mounts?
should I get 2 of them or what I'm confused and there is so much on this thread that its hard to get straight.

Yes. It fits both sides and that's the ones you want to use.

Those specs don't make sense. The top one says stud thread diameter is 1.5"/ .059 mm and the bottom one says 1.75"/ 1.75 mm. Something doesn't add up.

Agreed, but I don't recall a "stud" on the mount other than the frame locator. Someone's done this any said it worked, right? I remember seeing that it was good to go.

Yes it's been verified to work on both sides, SUV's and pickups. Quite a few guys have installed it.

That's what I thought. Just another example of published specs not always matching the real thing.

Long time lurker, well not too long but ....
Anyway, in case anyone is still wondering if the hummer's fit on NNBS tahoe, 2007 4wd, they do and ill upload the pics in a day or two

Posted this to be another one who verifies and will confirm with engine bay pics
Not sure how the truck ride's now as its still with the mechanic for tune-ups and stuff, but im excited that I've got those new mounts

Thanks everybody who shared their knowledge and also @windog for shedding light on the part number

My sincere apologies for taking a long time to update, i hope those may clarify any doubts, engine is a 5.3, nnbs, 2007 tahoe (2007+) replaced both sides with same part number but unable to get a clear picture for passenger side View attachment 196789
