slight vibration around 85-90 with slight throttle input
 

I am experiencing a slight vibration when maintaining a steady speed in the 85-90mph range. When I apply the throttle enough to keep up the pace, it seems like something in the drivetrain is out of spec.

Is there a guibo or some sort of bearing that could be going bad?

I'm hoping this is not an indicator of a larger issue.

anyone?

It might be your flex disc.

Whats a flex disc? Cost of repair?

Is a rubber piece between your drive shaft and tranny.

speed limit is 90 in MN? lol

Would you happen to know the cost of the part and cost to install? I hear that this vibration Im having can also be the torque converter but I rather try a cheaper route first if possible.>Thanks

Hmm...ive been battling the vibration issue for a year or two now. First i bought some kit off ebay that had cheap ass control arm bushings...so i bought oem bushings for the lower control arms and tried to press them in the cheap arms but the holes in the arms were way to big so i had my oem arms still but with 130K miles on them i was hesitent on using them cuz of the ball joints. they were very loose. So i pressed new oem bushings into them and overall no more shimmy on bumps etc. but at 80mph I get a front end vibration the steering wheel doesnt move or anything i just feel a vibration. The tires are new and balanced. I wanna blame the rotors but it has no impact on the steering and i dont feel anything through the peddle....but there is a definite vibration .....anyone have a clue? im not sure if a flex disc will cause this.....
