Once I get to exactly 70mph in my Camaro, the thing starts shaking real bad. The one time I went 100 my shifter was shaking so bad I could barley grab it. The car still tracks straight though. Is this just an alignment issue or do most third gens shake at higher speeds.

 

my car is smooth at 120mph. they are not suppose to shake. vibrations means something is unbalanced. perhaps driveshaft. wheels. etc. get them checked.

 

Same here, I would gat the wheels balanced first, then a aluminum equilibrated drive shaft.

 

I was getting some weird vibrations last summer, it was because a cap fell off of my rear u-joint.

and loopingz in your profile on the side it says you have a "9 bolts borg wagner" its a 9 bolt borg warner. just wanted to let ya know

 

Thanks for your input, now I will remember. It is gorrected!

 

Allignment has nothing to do with the vibration. The problem is most likely in the wheels/tires being out of balance. I don't know how so many people get these issues confused.

 

Never discount the Transmission mount. I have a 400 with a Turbo 400. We chased a vibration that pulsed at 65 and was speed related. Changed every thing. Last week had a custom drive shaft built that required a bigger loop. Still had the vibration. Took the transmission mount out and put a stock mount in and it is as smooth as any SCCA road racing car can be. Go figure. I believe that it was just so tight that it was transmitting all vibrations into the body.

 

Well that's out, I already had all my caps fall off at once. That was a whole lot of vibration! I guess I will try to balance the wheels again.

 

For me it was the torque arm mount that was shreded to pieces, i replaced that with a poly one and it was running perfect after that
