Broken Motor Mounts

[LanceD]

I just replaced a mount in an 07 escalade 6.2. It fits great. Here are side by side pics of old and new. New mount is the 25847739 part number.

Thanks for those pics.

This makes me want to change both of mine. The memory of doing one of them snaps me back to reality.

Luckily the driver side is much easier. Today I swapped out the mount on my 2011 Tahoe PPV. Side by side pics with the hummer mount.

Dude, I'm still so mentally drained from the memories of replacing mine, I barely floor it in fear of damaging my Anchor mount.

I still hammer on it. Nothing is better than Sport Mode, WOT, windows down through a tunnel. If I break it, then I'll get an H3 mount.

That's the spirit!

We have a SPORT mode? Got me thinking of my M3 days

Only if you have the BB Tune. It's an option to replace Tow/Haul mode. Also known as the "Haul Ass" button.

Or a supercharger. My Denali is in "sport mode" all the time.

You got me there. I'm confined to mods that don't have a price ending in "K"

Just to add another confirmation... Replaced the (severely broken) driver side mount on my '08 Yukon Denali yesterday with the H3 mount (PN 25847739). Fit great and the vehicle feels so much better now. Didn't really notice much (if any) change in any engine vibration feel.

Ok the driver side just broke on my 08 avalanche was it hard?

It wasn't too bad. I had watched a ton of the Youtube vids out there on it beforehand, so I had a good idea of my plan of attack. Went in from the top, removed the steering shaft (after securing the steering wheel), and just took my time.

Many write ups out there. I have one out there for a 4x4.

Here's the one I did. No pics but it chronicles what I did to the letter.

Add me to the list. 08 Yukon Denali. Last year I replaced the drivers mount. It's broken again. I'm also having issues with O2 sensor hitting the body under load with my long tube headers.


I went with Atomic Racing poly engine mounts made for the gmt900. I've been living with toasted mounts so long I doubt I'll notice much increase in NVH. Good price and fast shipping. More $$ than Hummer mounts but surely stronger!

After I install in the next week or so, I'll report back with my impressions.

Bad mount.

Those look like they might be harsh without any rubber at all but who knows. I was reading some guys over at pt.net that were running solid mounts and they said they weren't too bad but they didn't know the H3 mounts worked and there wasn't much choice for high HP applications. Actually is AFP a guy from that forum?

These have poly, so not as bad as solid mounts. Eventually I'll be cammed and supercharged so I'll skip the Hummer mounts.

Yes, atomic from pt.net. Great guy who really helped me tune my engine and transmission. Well, I paid for his help but $$ was cheap and he knew his stuff! Lol, and I'm not getting anything out of pushing his services and products.
