supra vibrating past 60mph

[jeddyminit]

so i took out my car on the freeway couple nights ago and i noticed past 60mph the whole car would vibrate under acceleration, but when my foot was off the pedal it would be fine. the faster i went the more violent the car would shake.
i already changed out the motor mounts and center carrier bearing on the driveshaft. what else should i look into? any help is appreciated.

thanks

Check the UniJoint alignment in the drive shaft, it should be o---o---o front to rear.

Just to repeat IJ (for the first time in SM history I'm sure... ) it should NOT look like this

Keep in mind this shaft is sitting flat on the ground in all 3 pictures.

If that all lines up, check and see if there's play in the carrier bearing. If that also checks out, see if you've got a wheel out of balance. I've seen a lot of people complain about vibrations and it's just because they've either flat spotted their tire or a wheel weight fell off.

There is side to side play on the carrier bearing. I will try and balance the rears but i highly doubt thats going to solve anything.. I use tape weights on my wheels so i dont think it would come off..
