it shakes a lil at 30 mph and 40 Mph a big shake, any other speed is fine, went 90 its smooth, I just got my Tires Balanced, and Aligned. And Still the Shake, What are any other Possible parts that can Make the car shake like this ? Friend said Maybe Driveshaft, but i'm not sure ? Thanks

 

And It a 91 Vert if that helps

 

what shakes... the seat the steering wheel... are you using the brakes? did it shake before the wheel balance...

 

Tell us where the vibrations is coming from. The front or rear? Also does the wheel shake? shake under braking?

If its from the drive train, suspect:
Drive shaft U-joints
Trans mounts
Motor mounts
Possibly (not sure) diff. mounts

Steering Wheel:
Bushings
Tie rods

Under Braking
Check rotors, may be warped...


I'm not sure about anything else that would make a vibration or shaking but I would suspect these first...

 

less than likely for the drivetrain if it happens in certain speeds.

 

The Whole Entire car shakes, if its in gear, out of gear, or even braking. I did drive it off of the Road when i crashed it a while ago but i fixed the damage from it, the rear tire had a terrible Camber.


I don't Think the Frame Being bent would make the car shake only 35-40 MPH.


Thx for Replying

 

The problem could be in the one rear tire with camber. Or did he fix it? ... Did the balancer check for tire seperation and bent rims?

 

It sounds to me like your driveshaft.I Damaged my driveshaft and the car would drive normally and smoothly untill About 80km and hour.Once I hit that speed,A terrible grinding sound would start and get louder and louder untill I hit about 140.It was as if armageddon itself was occuring inside the car.Horrible vibration all through the car that I could feel in my bones.I called dave at Mazdees and described the problem.His first guess was the driveshaft and after I drove over and had it replaced,IT drove smooth and perfect.Does this sound anything like what your experiencing?

 

not the driveshaft.... that would be a shake that gets worse as you speed up.

Not a bent car... your car would dog track or pull when you drive.

Have the balance double checked. you dont know how many times i've had to rebalance another techs job at work due to: weights flying off, porr balance to start with, laziness.

check for lumpy or separating tires.

you said its the whole car so pay special attn to the rear.
