  2. Suspension System DUAL CONTROL ARM SUSPENSION 13 806 '1. 'Supports the weight. 'Provides a smooth ride. •Allows rapid cornering with ut extreme body roll. 'Keeps tires in firm contact it the road. 'Prevents excessive body squat. MACPHERSON STRUT SYSTEM 'Prevents excessive body dive. •Allows front wheels to turn side-to-side for steering. •Works with the steering system to keep the wheels in correct alignment.
  3. Suspension System Basic Parts Control arm — movable lever that fastens the steering knuckle to the vehicle's body or frame. Steering Knuckle — provides a spindle or bearing support for the wheel hub, bearings and wheel assembly. Control arm bushings Kingpin Steering knuckle
  4. Suspension System Basic Parts Ball Joints — swivel joints that allow control arm and steering knuckle to move up and down and side to side. Today's complex import suspension systems aren[t tolerant af excessive wear. Sprinqs — supports the weight of the vehicle; permits the control arm and Wheel to move up and down.
  5. Suspension System Basic Parts Shock absorbers or dampeners — keeps the suspension from continuing to bounce after spring compression and extension. Control arm bushinq — sleeves that allows the control arm to swing up and down on the frame. Control arm bushings
  6. Suspension System LOW SPEED BUMP WITH THZ PATENTED LEHMAN LEAN SUSPENSION' LOW SPEED SUSPENSION BUMP WITH INDEPENDENT Non-independent suspension has both right and left wheel attached t the same solid axle. When one wheel hits a bump in the road, its upward movement causes a slight tilt of the other wheel. Independent suspension allows one wheel to move up and dow with minimal effect to the other.
  7. Suspension System upper control arm shock absorber coil spring stabilizer ball joints @ 2006 Merriam-Webster, Inc. rear shackle shock absorber leaf spring front hanger Coil sprinq is the most common type of spring found on modern vehicles. Leaf sprinqs are now limited to the rear of some cars.
  8. Suspension System Torsion bar (large spring rod) •One end is attached to the frame and the other to the lower control arm. 'Up and down of the suspension system twists the torsion bar. •It will then try to return to its original shape, moving the control arm to its original place.
  9. Suspension System Sway Bar (Stabilizer Bar) 'Used to keep the body from leaning excessively in sharp turns. 'Fastened to lower control arms. (rubber bushings are used) 'During cornering, centrifugal force makes the outside of body drop and Inside raise. 'The bar's resistance to twisting motion limits body lean in corners.
  10. Suspension System Shock absorbers •Limits spring compression-extension movements to smooth the vehicle's ride. •Without shock absorbers, the vehicle would continue to bounce up and down long after striking dip or hump in the road. O

'Strut assembly often replaces the upper control arm. 30647969 Cap 3546189 trut Mount 3546730 SWAY BAR
  12. Suspension System Checkinq Shock Absorber Condition Bounce test 'Push down on one corner of vehicle's body. •Release the body and count the number of times the vehicle rebounds. •Good — no more then two rebounds. Leakinq Shocks •Check for signs of leakage. 'If oily and wet, replace it. vCP4
  13. Suspension System Replacinq Coil Sprinqs Need to compress the coil spring, before removing it. Warning —A compressed coil spring has a tremendous amount of st ed energy.
  14. Suspension System Checkinq Ball Joints Ball joints Non-load Load carrier LOAD CARRIER • SPRAG CN FOLLOWER 0 'ON ON VACPHERSON $TAut 'If spring on lower control are, jack stand under the control arm. •If spring on upper control arm, jack stand goes under frame. If any play found, place it. PAtSSK* LOAD CARR t
  15. Suspension System Tie Rod Inspection Part shown above Inner tie rod Adjustment (closest to the sleeve vehicle center) Outer tie rod (closest to the wheel) Move the wheel side-to-side, should be no play.
  16. Suspension System Always grease all the grease points.
