Control arms/trailing arms?

[godwingn87]

I seem to be having an on going problem with my GN under WOT where the car sways left & right in the rear.. I have looked into it and it looks like the control arms are in pretty rough shape/rusty.. My car also appears to be riding crooked when I'm driving down the road.. I have a couple of questions to start- Is it control or trailing arms in the rear of our cars. I've heard it said both ways.
Second, is there a place that sales used arms for a good price? I've heard you can box stockers and they do well.. I wouldn't want to do mine as they appear to be bent a little.. I've had the front control arm bushings replaced recently and it helped a little but problem still not solved. I'm running about 27psi on alky and didn't notice it until I passed about 22 psi when I was tuning. It almost feels like when your hauling a heavy trailer and it tries to get away from you... Thanks in advanced for any help

Its both. Our control arms are trailing arms. Not all are. Some suspensions could be A-arm, ladder bar, panhard bar, etc.

You can get spare arms from a junkyard. They came on many cars. Note that the bolts holding them are body style bolts, and wont come out easily.

All of your 20+ year old arm bushings are likely trashed.
