1. Rear Suspension Styles

2. CBC Auto JF Rear wheel drive

3. CBC Auto JF Live Axle with leaf springs Wide leaf springs control side sway wellWide leaf springs control side sway well A large amount of unsprung weightA large amount of unsprung weight Leaf springs take up a lot of spaceLeaf springs take up a lot of space

4. CBC Auto JF For every action there is an equal & oposite reationFor every action there is an equal & oposite reation When the wheels turn clockwise, the the rear axle housing trys to turn counterclockwiseWhen the wheels turn clockwise, the the rear axle housing trys to turn counterclockwise Axle wind upAxle wind up

5. CBC Auto JF Note the axle is mounted off center on the spring This helps prevent axle wind up

6. CBC Auto JF Mounting one rear shock in the front of the axle and one behind the axle helps to reduce wind up and axle tramp

7. CBC Auto JF Live Axle with coil springs The upper control arms control lateral movement (side movement)The upper control arms control lateral movement (side movement) The lower control arms control differential torque (wind up)The lower control arms control differential torque (wind up) Side movement

8. CBC Auto JF Watt’s Link A Watt’s link allows the suspension to travel up and down while preventing the axle from moving side to side.

9. CBC Auto JF Watt’s Link used on a Mazda RX-7

10. CBC Auto JF Diff. Housing Note... single leaf spring on independent suspension (RWD)

11. CBC Auto JF Trailing arm suspension

12. CBC Auto JF When the “A” shaped control arms are mounted at an angle, they are called semi-trailing control arms When the “A” shaped control arms are mounted at an angle, they are called semi-trailing control arms Used on several sports cars Handles cornering loads better

13. CBC Auto JF Multilink independent rear susp. Note Hydraulic mount on this model Superior noise and vibration dampening Hyd. mount Nissan P-146

14. CBC Auto JF Rear suspensions on front wheel drive vehicles

15. CBC Auto JF Semi-independent rear suspension The axle assemble twists, which gives the semi- independent effectThe axle assemble twists, which gives the semi- independent effect

16. CBC Auto JF Semi-independent rear suspension The axle assembly acts as a sway barThe axle assembly acts as a sway bar Track bar controls side movementTrack bar controls side movement

17. CBC Auto JF Tracking bar with diagonal brace Another style also used with a semi- independent rear suspension

18. CBC Auto JF MacPherson strut rear suspension Is this Fords better idea???

19. CBC Auto JF MacPherson strut rear suspension Note... toe adjustment toe adjustment Toyota

20. CBC Auto JF Modified MacPherson strut rear suspension Common on FWD vehicles Ford

21. CBC Auto JF Double wishbone type rear suspension Some models have flexable rubber bushings Mazda

22. CBC Auto JF Torque loads create bushing and control arm deflection during braking, corning, acceleration and deceleration. This causes a toe change to enhance straight line stability Toe change during corning leads to quickerand more responsive steering
