Easy get rid of the tyre, replace with the spare and go for a run.
If it still there it might be driveline related, are the front hubs locked?
Unlock them and go for a run.

Also try rotating the tyres, drivers side to passengers side

Gday
Just change the same wheel and
check again. The squeaky grind is more likely to be a universal joint gone solid , that will make the whole vehicle shake.

Gday
You must also remember that the uni joint when worn out is not always loose. The rollers will become locked and rigid, the only way to find out is to undo the end of the shaft and move in all directions to see if one way is ceased.
Check all joints this way. If you have a centre bearing,
check it as
well.

You have mentioned vibration rather than wobble or shake so the following may not be useful.
GQ shake is common and there's lots of discussion across the net about various problems and solutions. Some solutions turn to panhard rod being replaced/repaired. Lifted
suspension seems to exaggerate the problem.
GQ's are apparently sensitive to balance of wheels and many people get on-car balance done - I tried this with a replacement set of wheels and it worked
well for me.
My original problem turned out to be near-new tyres being out of round. But I reckon the on-car balance with replacement wheels was better than the off-car balance that I have had done since.
Good luck

I would be checking tyres for out of round to start with .
the sqeak you mention under acceleration my guess would be uni joints , make sure you replace them with greasable ones
the steering wobble in
mine was found to be lack of preload on the front swivel head bearings . after about 10 yrs of putting up with it ,fixed .
