'93 Jimmy 4x4,4.3,W : Loud High Pitch noise

Is it an automatic? Does it "clang" like a person beating on a large piece of steel? when you gun the throttle out of gear does it come and go. If it does, its a Flexplate. Is it a stick? if so, does it do it when the clutch is in or out? Does it do this in neutral in the driveway or only while IN GEAR. In Gear and rolling means maybe a wheel bearing, so does it do it while Coasting? if your coasting and it stops its a transmission, if it continues, sounds like a wheel bearing front or rear on the passenger side.

Its easier to find it if you can do it in the driveway, as running down the road next to it can get really tiring for the wife.

Or does it Squeal like a revolving part held again a grinder might?

Figure out if its a transmission throwout bearing problem or a clutch issue, or if automatic if it has to do with Transmission or maybe the flexplate is cracked and clanging around.

You need to isolate this down fast as if its a wheel bearing, that can be cheap if found early, or extremely rude (expensive and dangerous to others) if found too late or neglected.

Not Really it is a more steady whine, but not the squeel sound of a belt or powersteering pump.

It goes in any gear, including park, and reverse.

had the wheel berrings, Toression bar, and sway bar replaced/repaired

More like that, thats what made me think berring. It stops for a second when you intialily hit the acceceratator, bu when your steady on the gas it starts again.
