Thats the one. Pretty sure thats whats going on. I wonder if the actual TSB was updated to include more years.

Ok, so I have the plastic insulator thing on order and have figured out the part number for the mount thanks to @915_Tahoe. The mount and lower cushion are pretty cheap. I suppose I should replace it all since it will be in my hand when I take it apart.

Ordered the insulator, upper and lower body mount. Not happy to have to lift the body up off the frame but will update as things progress.

Just a thought as we like to help spend other people's money here, but since you will need to take all the mounting bolts out at least on the one side of your vehicle, why not just replace all of them on that side and be done with that side.

From what I have read as well as what I see form a visual inspection all my body mounts are in good shape. I understand the noise is due more to the design and movement of the mount rather than the condition. I ordered the mount parts too as insurance so I have them in hand when I take it apart. Replacing all of them would come to the tune of $400 per side.

I see - Like I said, we like to help spend other people's money.

I was gonna say, the body mounts aren’t cheap. I was looking into doing the Trailblazer body mount swap in order to drop the body 1/2” or whatever it is until I saw the complete set of mounts costs a small fortune. Glad to hear you have a plan for this issue George!

Why not go Poly?

Less than $200 for all of the body mounts and they won't dry rot or deteriorate like rubber.

Plus you can get them in red for more HP.
