2013 Tahoe gear swap 3.08-4.10 questions

Remind me again what a semi-floating and full-floating axle is, or what the differences are?

Are they the same as a solid axle and independent axle? If so, I'm just not used to hearing them called semi or full floaters

The main feature is that in a semi-floater, the axle shaft is doing double duty - providing twist AND carrying the weight. In a full-floater, the axle only provides twist. The axle housing carries the weight. Makes it much more durable and robust.

I have the 10.5" full floater in my Suburban 2500. I call it the Godzilla axle. The manufacturer, American Axle, rates it to 8600 lbs load-carrying capacity. The limiting factor is the weight rating of my tires.

Well, if memory serves, all 2007 Yukon and Yukon XL Denalis were AWD, so the axle didn't appear until 2008 and was used until 2014. Mine came from a RWD Escalade. This also applies to Escalade ESV and Yukon XL Denali with RWD.

My local junkyard has 3 Denali’s. They are older models…..I checked on LQK online and they have a few for $236. Some others are more expensive.

What years and what does LKQ have? 9.5" AXN?
