Broken Motor Mounts

[bottomline2000]

Yeah I've literally never heard of the passenger side going bad. I suppose it's possible but unlikely.

The torque of the engine pulls on the drivers side mount. My 05 GTO literally ripped the drivers side mount in half. I went to a billet mount with rubber inserts afterwards. NVH went up slightly, but at least the engine stays in the car. Suxs to see this problem with the trucks since the mount is so complicated.

Not being a jerk but yes. At one point or another, I think there has been a complaint about all of these. Chief of which are motor mounts and cracks in the dash.

My interest is renewed since I just bought a bagged 08 Silverado CC.

Pics/video or it never happened . Any update on the custom motor mount that was recently installed? Initially no complaints about vibrations but some times your opinion changes after more testing.

Just updated my 4wd how to thread on this. Just hit 7 months on my el cheapo mount from Amazon. No issues so far.

If you look at the auto zone part number. It is the same as the anchor brand on Rock auto, O'Rielley's house brand, and Advanced auto also.

Same as Amazon where I found one for a steal (28 bucks). Anchor brand and all.

Yes, evidently the motor mount issue is something that GM has failed to properly diagnose because I had a '99 Tahoe that had the issue with the broken motor mount. I guess because I really enjoyed the '99 Tahoe, I decided to purchase a '08 Tahoe, and guess what...YES, another broken motor mount. My '08 also has the cracked dash. I am keeping my eyes open for the same issues with the newer SUVs because I do like GM SUVs, but I will definitely hesitate to buy another one if these issues persists.

tbqh GM doesn't give a damn because if they did these issues would have not happened. My 2004 was bulletproof and the jury is out on my 2013. Only time will tell. Good Luck.

Someone provided feedback that there is a heavy duty motor mount sold by GM that looks like it fits the hummer H3.

Details below. Similar engine I think but not sure if it will work or not.

I saw this mentioned in another thread recently and am considering trying it. Actually, I'd replace both with it. I'm not doing anything until I'm ready to install headers, though.

I did this yesterday. Yea It's a real pain for sure. You basically have to work completely blind to get those top bolts on the block. My truck is an AWD, removing the steering shaft is a big help, and it's only 2 bolts. I didn't remove the drivers halfshaft... didn't see the need.

Did you use the Hummer mount?

Went to the dealer today. They told me the Hummer one won't fit...

The said $100 for a new OEM mount and 2.1 hours to install it.

I'd make them show me both and explain why it won't fit.

WTF....some people successfully installed. Sometimes dealerships are dumb. Can anyone that installed or plan to install take some pics and compare?

@NathanJax, you gave them same model # posted above?

I have to stop back by there so I'll talk to another person about it as well.
