What did you do to your NNBS GMT900 Tahoe/Yukon Today?

I balanced mine like a see-saw on some jack stands to find the center of balance sans motor.

And what did you learn? How much did it move?

I learned where I should position it on my lift. Ended up being about 9.5" back from where I normally center it.

It took three tries and was still slightly rear-heavy, but I could lift it with one finger in the hitch. I feel that was close enough and didn't warrant another dance with the jack and stands.

So percentage wise.... 10.5% ???

Add fuel and rebalance.

I considered for a brief second stopping and calculating that, but quickly lost interest cuz I wanted to get under it ASAP. I'm lazy.

Lol

If I ever lift it or any Tahoe again with no engine, I'm gonna remove the third row seats and drain or add fuel to put it at the 1/4 tank mark. I drew a mark on the floor for reference for this project.

Tisk tisk.... all that talk about it and no follow through.

Turns out my estimate of being 8”-12” further back was pretty damn close then.

Be sure to post pics of your new drain set-up in action.

You do know your CG will move back a tiny bit more when you drain your transmission, right?

Yeah, but not enough to exert anything the lift's anchors won't hold!

You were pretty close. But a little bit made quite a difference. Out of the three tries, the jack and stands were positioned within a ~4" area.

Just know it'll make your interior feel smaller and more closed in. Not good if you're a claustrophobe.

My 300 was all black inside.
