Broken Motor Mounts

[the blur]

2011 Escalade, 75,000 miles. Just did a motor mount. Sounded like a rear end clunk. 4 different people heard it in the rear. I have no idea what the motor was banging on, to make it sound like it was coming from the rear. Only under hard acceleration was it noticeable.

Have the extended warranty, dealer changed it, and banged the warranty company pretty hard. Dealer still sucks, but I only had a small deductible to pay.

Preach. I heard mine the same way. There's been a few posts on here of people chasing a "rear end clunk" only to find it was the mount. I'm guessing the sound travels through the frame but is most audible below and behind the driver because of the extra sound and thermal insulation on the firewall and floorboard.

Dropped off my truck at the dealer this morning to replace the drivers side mount, as soon as we look under neath, we notice the passenger side is completely sheared off...

expensive day...

How da hell does that happen? Maybe the PO did some heavy reversing, like pushing a loaded trailer uphill in reverse?

So did you do the same mount on both sides?

Once the drivers side is busted, it puts twice the strain on the passenger side

Yeah, but I was thinking it would just compress the passenger side more, much less shear it. I guess I'll order two mounts when I'm ready to do mine. Trans mount ok?

i see all these blown mounts and have to wonder how i never tore one up in my 97 3500 or the 03 2500 hd. i plowed with both and showed them no mercy.

the 97 i put 175,000 on it, the 03 had 105,000 when i sold it.

Because those mounts were solid rubber unlike the 07- up which are liquid filled. That's why the Hummer mounts are better replacements, they're solid rubber too.
