Sloppy tie rod ends, or any other slop in the steering/suspension will cause just that when the slightly unbalanced wheel's rotation speed hits the resonant frequency of the failing structure. Which accelerates the wear of the failing part, which will often lower the resonant frequency of the structure so the vibration/hop happens at a lower road speeds.
So... replace whatever's sloppy, and be a zealot about tire rotation and balancing for as long as you've got a difficult to balance combination hanging on the ends of the axles. I'm wondering if the tire monkey who mounted and balanced your set even knows about match mounting. A lot of them don't these days.

The rod ends are on the list, but I was hoping to get that done after the plenum. (which I still do not have the plate yet.
)About how long do I have till the steering falls apart? lol

I would start by ruling things out first.
1. With tire balancing, does the vibe move or change?
2. Condition of shocks, age most importantly, leaks, could just take out and see if compressible by hand.
3. Visually inspect the TREs. Clean them up. Get load off the steering and check for play. Lube up all your TREs.
Take a systematic approach as it will help you get a better idea and confidence in some parts over others.

There's no telling, but when it goes you'll be the first to know.
Magnifying what Wh1t3NuKle has said, it seems a good time to get serious about inspecting the front suspension and steering very carefully. Especially with a 4WD it can be a real pain to troubleshoot front wheel motion -- there are lots and lots of parts flying in formation under there and any one of them being worn can manifest itself as wheels doing their own things and wearing tires at a helluva rate, too.
That said, replacing the tie rod ends you know to be sloppy with good quality replacements would be a very good thing to do, and if you make it a point to always lube them when doing oil changes you'll probably never have to replace them again. I've never replaced a tie rod end that was consistently lubed on schedule unless there were monster tires involved.
