I need help Bad Vibration

[4nturbo]

Im haveing some problems figuring this vibration out !!!
First off the car is a 95 Talon AWD Automatic pretty much stock
The vibration starts at around 50 mph and up. It is most noticeable at hi way speeds under even a slight load. If i let off the gas the vibration go's away touch the gas even a little and the vibration come's back. My first thought was a wheel or tire issue so I replaced them with NEW Mags and Tires ( I didn't like the stock ones anyway) did not help. Next I replaced all 4 rotors and brake pads with new no help. Also let me also say the steering wheel is rock steady with no vibration. The next thing I did was replace all 3 U-joints in the drive shaft did not fix problem. The carrier bearings and the axle's look to be in good condition no torn cv boots ect. I have also checked the ball joints and tie-rod ends they seem to be in good condition. also the car only has 78k miles. Just today I swaped out the drive shaft with a buddys drive shaft (known good) still no help. The motor mounts look good not torn or coming apart. Short off swapping out all the Axles and hub bearings one at a time Im running out of ideas on how to fix this problem. The only other thought I had was that it mite be Toqure converter shutter but the vibration seems to be brought on by speed and load not RPM.
Any ideas Im about ready to put a match to this thing its pissing me off

check your front end if you can jack the car up shake the front tire right to left feel for play. Did you get the tire's balanced when installed

I did check the front end for play tie-rods are good and tight. i also checked the ball joints at all for wheels. And yes the tires were ballenced.
Although I did not get hube centric rings with the new wheel that could also be an issue but I don't think that is the problem
