  1. Alignment Fundamentals Part One

  2. Suspension Systems • Designed to: • provide satisfactory vehicle control • acceptable driver effort • Maintains directional stability: • on various road surfaces • all types of weather • loaded and unloaded • towing

  3. Road Variables • Road Crown • Bumps & Pot Holes • Crosswinds & Cross winds created by other vehicles • Road surfaces • Side forces • Drive axle forces • Suspension part movement

  4. Rear Wheel Alignment & Vehicle Tracking • Thrust Line – Imaginary line @ 90 degree angle to the centerline of the rear wheels • Rear Wheel Offset – axle asm out of position, not parallel to centerline

  5. Improper Thrust Angle

  6. Wheel Base • The distance between the center of the front & rear wheels

  7. Tracking • Position of the rear wheels in relationship to the front

  8. Ride Height • The distance between the frame & the ground. If distance varied over ¼” between sides, handling can be affected.

  9. Camber Fundamentals • Inward/outward tilt of wheel from true vertical. • Vehicle will pull to side most positive. • Affects tire wear.

  10. Camber Fundamentals Negative Camber Positive Camber

  11. Jounce & Rebound • Jounce - Upward wheel movement • Rebound – Downward wheel movement

  12. Caster Fundamentals • Tilt of a line that intersects the lower and upper ball joints (strut mount) in relation to true vertical

  13. Caster Fundamentals

  14. Positive Caster • Helps return to straight ahead position • Increases steering effort, the wheels try to stay straight • Pos caster helps maintain directional stability • Too much affects steering, rapid wheel return • Pulls to side with the most pos caster.

  15. Negative Caster • Decreases directional stability • Reduces steering effort

  16. Tire Wear • Caster has effect on tire wear
