I broke 3 bolts the other day when I was lowering the rear end. 2 were in the top part of that arm and 1 was on the pass. side for the lower arm. What exactly do these arms do? And how can I possibly get these bolts out? one of them is broken inside the lower arm. Do you think I could drive it a few miles to a shop to get the bolts removed? I didn't want to try driving very far. I did however drive it around the block because I was so anxious becuase I havent driven it in about 3 months.

 

The lower part is the panhard rod, the upper is the panhard rod brace. The panhard rod keeps the rear end centered under the car while turning.

 

Thanks, I was really getting annoyed because I didn't know the name.

 

GM also likes to call them the track bar and track bar brace.
