1. The ______system allows a vehicle’s tires & wheels to move up and down as they roll.
2. Suspension can be grouped into 2 broad categories: ______& ______.
3. The perfect suspension system balances understeer and oversteer, resulting in ______steering.
4. Compressing springs is known as ______. As springs extend, they are said to ______.
5. Springs can be one of 4 types: ______, ______, ______, & ______.
6. ______weight is all of the weight supported by the springs. ______weight is all of the weight not supported by the springs. The more sprung weight, the better the vehicle will ride.
7. Control arms are connected to the steering knuckles with pivoting joints called ______joints.
8. ______limit spring oscillations (jounce & rebound), but don’t effect ride height.
9. ______shocks are filled with low pressure nitrogen gas to prevent (oil) fluid aeration (bubble formation).
10. Options on shock absorbers include the ____________feature & adjustable stiffness.
11. A ______assembly consists of a shock, coil spring & an upper damper/pivot bearing. (No upper ball joint)
12. A ______bar or stabilizer bar prevents the vehicle body from leaning excessively in sharp turns.
13. A ______rod is a lateral control rod that limits sidetoside axle movement during cornering.
14. Suspension systems can be of the ______ ______arm, ______bar, or the
______design. Slightly modified versions of each type can be found.
15. ______suspension systems can be either, independent, semiindependent, or nonindependent.
16. Electronic ______control systems use computerization to monitor and maintain correct ride height.
17. ______suspensions use PCMcontrolled hydraulics for ride control instead of springs & shocks. ~~~ 18. The ______system must provide control of the steering wheels, maintaining the correct amount of effort to transmit “road feel” to the driver’s hands.
19. In rack & pinion steering, the ______is a flat steel bar with gear teeth. The ______is a small gear that meshes with the rack, it is rotated by the steering wheel and steering shaft.
20. ______steering columns help prevent driver chest & face injury during collisions.
21. ____________steering boxes are heavier & more complicated than rack & pinion.
22. On parallelogram steering, the ______arm and the ______arm support the ends of the center link. Tie rods & tie rod ends connect the steering system center parts to the knuckles.
