I was just more curious because when i was changing the sway bar i grabbed one of the bars in the suspension (not sure which one) but it goes to a low mounted bracket on the rear spindle and looks more like a solid bar than a control arm. And the bushing which connected it to the spindle seemed really loose cause i could move/twist the bar with my hands. Is this the trailing arm?
