I have owned a 87 ss for 12 years now and cant figure out why the right rear of car sits lower. I have replaced shocks,coil springs. What else is there? could this be a twist in the frame?any ideals or thoughts would be very helpful.

 

Hi there and welcome to the forum!!
If you have replaced shocks and springs then yes, it is possible that your frame could be twisted. If your Monte has ever been raced or driven with sudden and repeated hard accelerations, then it is a very real possibility that the frame is twisted. 4th Gen Montes (G bodies) are notorious for what they call the GBody twist.
Here is some information I got from another source that may give you some ideas on what else to look for.
"Start by checking the simple things. Body mounts and if your frame might be rotted around them. Most g-bodies have some rot around the bushings. Replace the mounts and fix the frame with the repair washers then go from there. You can help a lot with the simple things, factory frame braces from Grand Prix's, aftermarket rear frame/bumper tie in, radiator cross bars, back seats cross bars, etc. "

 

The GBody Twist. That sounds like a hip new dance move.

 

I laughed about it when I first heard of it too.
Unfortunately, it is all too real.

 

thanks I will look further into it
