Can I have some help with a TC drop

So I've removed my Sway Bar, replaced my muffler, replaced my Ujoints but I'm still having vibration under acceleration after doing the budget 2" lift that floats around here.

After replacing all those things it's gotten significantly better, but it's not gone. It gets better when I load the car up with 4 bodies a dog and 3 days worth of camping gear, so I'm at the point where I can only imagine a tcase drop is the missing piece. Being as the extra weight simulates the drop in the driveline a tcase drop would create.

Is there a kit/height you guys recommend for my 2" lift? And can I get it done without a jack? Can I just do one side then the other?

Thanks for the info guys
