Will an escalade EXT rear axle bolt up to a tahoe?

[man n black]

I have a 2013 tahoe and the rear axle went out. destroyed. almost irreparable.....

@OP Please elaborate.

Almost everything inside any axle housing regardless of make should be removeable, replaceable and upgradeable.

You might be better served by upgrading the parts inside the current axle housing rather than switching to an used OEM housing with unknown history.
