Tips/tricks for separating lower ball joint 2018 Tahoe PPV?

[CrashTestDummy]

We're mostly done loosening/removing everything on the front of our '18 PPV to install the Beltech 2" drop kit. We are struggling with separating the lower ball joint from the spindle, though. We've tried wailing on it with a BFH, slipping something between the LCA and spindle and jacking it up to hopefully wedge the piece between the two and separate them, heat with a BFH, pretty much everything I can think of except a ball joint separator tool. I'd like to NOT do that, as it'll tear up the boot. Heck, we even got out our sorta-power tool and wedged that between the LCA and spindle. Nada!!

We used a pitman arm puller on the tie rod and upper ball joints, but, sadly, it's too short for the lower. IIRC, when we did our '10 Tahoe, all it took was a jack under the lower stud and a BFH. That's not getting us anywhere this time. It's pretty rust-free, being a Texas vehicle, but I do now have it soaking in PB Blaster in case that helps any.

While we could do LCAs AND the drop kit, it'll add another $500 to the project. The ball joints and bushings look in otherwise good shape for a 103K mile vehicle.

Thoughts? Tips? Tricks? Thanks!!

Penetrative fluids, and worst case scenario heating up the spindle at risk of ruining the joint.

Combination of these was how I did mine with the same kit. I remember having a hard time as well.

On the old cast iron spindles two hammers would pop it out. One big hammer to buck it with and a good sized ball peen to hit it. Hit the knuckle on the side. Has never failed me. Not sure what's actually there on your machine.
