The safety is just that - for safety. I'm willing to bet that most all motor mounts have some kind of fail safe in the event of failure.

Yes they addressed my problem, for $1200. I'm sure they're happy. I'm happy they fixed the problem, but not happy that this is the 2nd time I've had to replace mounts, this time at my expense.

In my case I was hearing and feeling a bad clunk every time I pulled away from a stop. The slip joint issue is similar bur far less severe. And the true test is to pop open the hood, have someone stand alongside the truck, the with your foot firmly on the brake hit the gas pedal quickly for a moment. In my case the engine jumped 3 inches on the drivers side. The noise was the mount hitting the safety cage round the mount that prevents the engine from moving too far.

I guess the safety cage on the mount is an indication that GM kinda knows they have a problem with these mounts?

I have read other posts about broken motor mounts and this was the first I read of the clunk as a symptom along with it.

The problem you described is exactly what my brothers Denali was having. 2007 6.2. He kept thinking it was something in the drive shafts/axels with the AWD, I was thinking the slip joint as it was what commonly came up when researching the problem. I read from posts long before about how easy it was to test if you have a bad motor mount, but nothing really along the line of all the symptoms that went along with it. Thank you for your post, now my brother is at ease and can finally get the problem fixed!

Ill try to get a video of the clunk and the engine if I can.
