Anyone hear balance driveshafts?

If not do you know anyone local to me that will?

Fayette county, PA.

thank you

 

I had my stock steel driveshaft "balanced" by a good shop using a magnetic pulse system; no improvement with the 70 mph vibration. Replaced the shaft with an aftermarket shaft (Denny's), no more vibration.

 

No idea where that is in PA, but Denny's does all my DS work, he's up here in Buffalo, NY.

 

Thanks for the replies.

there is actually a place 20 mins. away.

its called fayette welding, but they do drive shafts.

i bought my aluminum drive shaft used but it still vibrates, however i used the same u-joint.
is it possible my drive shaft is out of balance or could it be the u-joint?

it starts vibrating at 70 and quits at around 90. it's so annoying!!

(when doing 70) i let off the gas it does not vibrate. as soon as i touch the pedal it starts.
