I have a 2011 Denali with broken driver side. I have been look at the threads and saw where Jennifer from GMC customer service can possibly help with this problem.

If your ride is out of warranty, not seeing how GM customer service can help you.
Yeah good luck. Broken motor mounts are common even after replaced. You can use the H3 mounts. Guys have had good success with those.

Replace all three at same time regardless of whatever you choose. The weakest motor mount immediately begins wearing out the newest mount.
Motor mounts are tuned. When they wear, they rely more on the other dampeners to compensate. There actually is a scientific equation to each mount set up based on lifespan, comfort, performance, etc.

Would you happen to know the part number for the H3 motor mount or what year to ask for. Thanks

Can anyone advise me on how difficult it is to change all 3 motor mounts on a 2007 Yukon XL Denali (6.2L)? I don't believe that I have a broken one, but with 135k miles on it, perhaps it makes sense to be proactive, if it is not a major pain in the ass to do so.

2wd or awd?
2wd easy from the buttom, just support engine and pull one at a time. with front diff just requires a little more time to work the bolts to the engine block, with stock exhaust manifolds it shouldnt be bad
transmission iirc is on a removable cross member. support transmission/tcase . unbolt it and the crossmember to swap
