Inspect an independent rear suspension by looking for signs of damage on the bushings or excess rust on the fastening hardware or suspension components. As the wheels of a vehicle move up and down, the suspension must accommodate this movement and still keep the wheel from moving away from the vehicle or inward toward the center of the vehicle. Electronic Suspension Systems 120. Which of the following about the scenario is true? Suspension is the term given to the system of shock absorbers and linkages that connect a car to its wheels. The steering system converts the rotation of the steering wheel into a swivelling movement of the road wheels in such a way that the steering-wheel rim turns a long way to move the road wheels a short way. Basically, the hydraulic system is right in the middle between the two. Some aluminium components are found in springs and dampers, but the most important aluminium applications are the structural suspension parts, i.e. lmaria86. Typical gas-charged shocks are pressurized with 130 to 150 PSI. 1 - The EXPLORE Method.
