Question for everyone: I just rebuilt my entire front end with all new Moog parts. I replaced pretty much all the links and also the ball joints. I have just balanced the tires and performed a wheel alignment. My car still shakes over 60 just like it did before I did all thei work. Does anyone have any idea what else could be causing this? My car is a 87 Iroc-z Convertible.

 

drive shaft?Maybe if it is out of balance. Maybe it is out of shape due to contact with foreign object.

 

would the drive shaft couse only the front to shake?

 

Well if only the front chakes it could be that the new pieces you put in are not set-up right. It could aslo be warped rotors. A driveshaft with worn u joints comes to my mind. You will feel that vibration all over the car though.

 

Look at this....I had the same problem.....still do.....there is some info that may be useful to you though....
