This type of spring comprises a long bar that connects between the frame and the lower/upper control arm.
What is a torsion bar?
Only this type of suspension system can set diagnostic trouble codes.
What is Active Air Suspension?
If this is faulty, you may have a noticeable drop is engine speed when the steering wheel is turned at idle.
What is the power steering pressure switch?
An integral part of any suspension system used to isolate two metal parts from contacting each other.
What is a bushing?
This steering system has a large tube that moves side to side and is directly attached to the outer tie rod end.
What is a rack and pinion steering system?

What is CAN (Controller Area Network)?
In this system, the driver can select pre-programmed suspension stiffness.
What is an air suspension system?
This part is found only on the rear of a vehicle and takes the place of a strut rod.
