Across
  1. 2. A steel bar attached to the lower control arms or axle assembly and to the body or frame; designed to minimize body roll when the vehicle is cornering. Also called sway bar or anti-roll bar.
  2. 3. A depended style rear axle that drives the wheels
  3. 8. A suspension component that dampens the oscillations (bounce) of a spring
  4. 10. In springs, the number of times a spring oscillates or bounces before returning to its rest point
  5. 13. A method of suspending the wheels on a vehicle so that the movement of one wheel affects the opposite wheel
  6. 15. A small fitting threaded into a component for the injection of grease.
  7. 16. The angle of the steering axis with respect to the vertical axis only viewed from the side.
  8. 17. A tool used to compress the spring in a MacPherson-type strut for disassembly and assembly.
  9. 18. A tool used to free the axle from the bearing in the steering knuckle.
  10. 22. A reference line that splits the vehicle in half
  11. 24. The space frame or unitized body construction approach used for most modern cars, in which there is no separate frame.
  12. 25. The height at which the vehicle should rest on its suspension
  13. 26. A front suspension system in which the steering knuckle pivots on upper and lower ball joints and the strut is mounted rigidly to the body at the upper strut mount.
  14. 29. The most damaging wheel alignment angle. Compares the distance of the front positions of each wheel on the same axle to their rear positions.
  15. 31. A strut-style shock absorber that has the spring separate from the strut.
  16. 32. A thick, tough bag filled with air that acts as a spring
  17. 33. A length of steel bar fastened to a control arm at one point and the vehicle’s frame at another.
  18. 34. A bar used in many rear suspensions to limit front and rear movement of the rear axle.
  19. 36. A combined coil spring, shock absorber, and bearing plate used as a front suspension component in many front wheel drive cars.
  20. 37. Vehicle weight that is carried by the springs.
Down
  1. 1. A tool used to safely compress coil springs for removal and installation
  2. 4. A method of suspending the wheels on a vehicle that permits each wheel to respond individually to varying road conditions
  3. 5. Upward movement of a wheel that compresses the spring.
  4. 6. Inspecting steering and suspension components prior to performing a wheel alignment.
  5. 7. A length of steel wound into a coil shape
  6. 9. A wheel alignment angle referencing the tracking of the rear suspension compared to its geometric centerline
  7. 11. A long, semi-elliptical piece of flattened steel used on the rear of many vehicles.
  8. 12. A ball joint that supports the vehicle weight carried by the springs
  9. 14. A system that uses a fixed rear axle that twists slightly under loads.
  10. 17. The amount of force needed to compress or twist a spring a certain amount.
  11. 19. Vehicle weight that is suspended beneath the springs and therefore is not carried by the springs.
  12. 20. A driving condition in which the front tires reach their cornering limit before the rear tires.
  13. 21. A solid rear axle that does not drive the rear wheels.
  14. 23. The release of stored energy from a spring.
  15. 27. The portion of a body-over-frame vehicle on which the body is mounted
  16. 28. performed by the technician to look for obvious concerns, such as fluid leaks or severely worn tires.
