Broken Motor Mounts

little space at the bottom in there? idk

To add to the H3 mount reviews..

There are small vibrations through the steering wheel and brake pedal at times, low rpms, near idle.
Feels more like a typical 90's vehicle. If you want Lexus smoothness, or to save some bucks, get stock fluid filled.

No regrets at all, I prefer the durability here, just know there is a little tradeoff.

oh yeah. I still need to order and do the passengers side. but other than no longer having the click/clunk when starting. I haven't noticed any negatives to the hummer mount on a hybrid. since they don't idle when stopped very often, harder seems to be just fine.

I gotta get that 2nd one ordered. I see a bit of timing retard under certain conditions and before I run some hpt logs to try and tune it out, I wanna make sure it's not the motor sitting on the hard cross pin on that side the knock sensors are hearing. I put some 93 in it and didn't see any change, so my theory is all these bad mount aren't great for the timing either since it's basically metal to metal on the mount once it rubber rips

My drivers side has been busted for a few years now, and I've had a GM one sitting in the shop to replace it with. One day it will get done.

I just did this project. At the same time, I also replaced the transmission mounts and I replaced the front sway bar bushings and links. My two teenage boys helped me and they like when I write instructions so that they can make progress when I'm busy working or grabbing another beer. So I created a DIY write up and made notes during the work. I just updated my DIY and am posting it here in the hopes that it will be useful to others who follow.

Please note that I started by plagiarizing an earlier DIY write up so some of the text may look familiar. Also, I'm sure that I have typos and other problems. Message me if you catch anything that needs fixed and I'll update and repost.

GOOD LUCK!
