  1. Steering Going in the right direction

  2. Steering systems • Conventional (parallelogram) • Rack & Pinion • Electronic (new in 2002) • steer by wire • Audi/Volvo

  3. Conventional Adjuster Sleeve Gear Box Idle Arms PS Pump Pitman Arm center link Tie Rod

  4. How it works

  5. Conventional Steering • AA Pitman Arm • BB Gear Box • CC Center Link • DD Idler Arm • EE Tie Rods

  6. Recalculating Ball • used on many trucks and SUVs • linkage that turns the wheels

  7. Inside the gear box Seal • Worm gear • threads are filled with ball bearings • recirculate through the gear as it turns. • without the balls in the steering gear, the teeth would come out of contact with each other for a moment, making the steering wheel feel loose

  8. Rack & Pinion

  9. Rack & Pinion • Rack & Pinion Eliminates center link, idler arms, & gear box

  10. Rack & Pinion

  11. Pinion Gear Rack Rack & Pinion

  12. Power Rack & Pinion • two fluid ports, • one on either side of the piston. • Supplying higher-pressure fluid to one side of the piston • forces the piston to move, • which in turn moves the rack, providing the power assist.

  13. Conventional VS. Rack & Pinion

  14. Steer by Wire • Sensors pick up the driver's steering inputs and send this information to two microcomputers which, in turn, control an electrically driven steering gear. • completely eliminate the mechanical connection between the steering wheel and the steering

  15. Idler arms By replacing worn idler arms you can reduce vehicle wander, excessive play in the steering wheel and abnormal tire wear.

  16. Idler Arms Idler Arms hold the steering linkage in place.

  17. Manual Steering • Steering Linkage • Parallelogram Steering Linkage • Rack and Pinion • Manual Steering Gear • Steering Wheel & Column • Steering Dampener

  18. Power Steering • External Piston Linkage System • Internal Piston System • Power Assist Rack & Pinion • Components

  19. Electronically Controlled Power Steering Systems • Electric/Electronic Rack & Pinion System

  20. Ball Joints • Ball Joints are the pivot points on which the front wheels turn. By replacing worn ball joints with • Ball Joints, you can reduce front-end noise, looseness and tire wear.

  21. Power Steering Pumps • Loud squealing cause by a worn or loose Power steering belt

  22. Rotary pump at work

  23. Power Steering Gear Box

  24. Power Steering Box

  25. Steering column

  26. Steering column

  27. Steering column

  28. Steering Knuckle

  29. Tie Rod to Wheel
