i was driving on the highway last weeek when all of a sudden my car started to shake really bad. i limped it hime and had my uncle look at it today and we found that a bar on the rear had snapped causing the passenger side tire to shake. it runs from the middle off the car to the tire is threaded on both ends and attached to adjustment pieces for realignment. he did not know the name of the part so im looking for the name so i can get it replaced

 

Sounds like a rear lateral arm. Does it look like the bar I am showing in the pic below with the red lines by it?



If so, I know this as a rear lateral bar. Sadly, RockAuto.com does not have a pic of a lateral bar....

 

here is a link to the parts list with a picture LINK W SUSPENSION/REAR; W SUSPENSION/REAR (JL9); W SUSPENSION/REAR (JL9,J65); W19-27 SUSPENSION/REAR (JL9,J65); WS69 SUSPENSION/REAR (JL9,J65);. Fits: 2000 Chevrolet Monte Carlo SS | Nalley Buick GMC Brunswick

 

My car has same problem and in the diagram it's the bar where number 32 is and it's bent what is that bar called ??

 

I believe that is the trailing arm or the track bar. Leaning towards the track bar.

 

Its called a Lateral arm..... Highlighted/outlined here in red...
Yours is the same one on the opposite side correct?

 

Your right David... couldnt remember that name though haha.

 

I got it from Jason(Maniac) post #2
