Lifted Caddy throws me around over bumps, uneven roads,

Did u do it yourself? If the shocks were not changed they can be stretched and cause uneven ride.

No, and yea Shocks were changed.

So I replaced the lower ball joints and don't really see a difference. Oh well.

I know this thread is 5 months old, but if you're still having issues and haven't replaced you panhard bar with the Spohn yet, you definitely need to. I'm about 90% sure that's your problem. Spohn GMSUV-104B Adjustable Rear Panhard Track Bar is what you need.
