Trailing arms are a type of control arm used on the rear of older vehicles. They are phased out on newer cars since the nature of this system causes camber angles to change when cornering. As with other control arms, trailing arms utilize bushings and ball joints to connect them to the frame and wheel.
Trailing arms will more likely require the bushings or ball joints replaced than the actual arm itself. Still, extreme circumstances, rust, and other possibilites could lead to the arm itself to require replacement.
Replacing control arms varies in difficulty depending on the vehicle, its age and condition. Always consult with an automotive technician if you are unsure about any repair!
