What Did You Learn This Month?
Night School would not be complete without a quiz! Don't worry about your test-taking skills or grades. This is an open-magazine, true or false test. Clues can be found within the Night School text, photos and captions. Have a good month!
True or False Questions:
1. A beam axle with leaf springs is a strong, reliable frontend design. Load ratings reflect the beam size, spring rate, frame gauge, and the steering gear and linkage stamina.
2. Loose kingpin bushings and pins cause "kingpin shimmy." Worn ball joints can create a similar effect on A-arm suspension systems.
3. Ford twin I-beam front suspension uses semi-elliptic leaf springs, just like the 1964 and earlier Ford front suspension designs.
4. Frontend wander can be a kingpin issue. It can also be the result of loose leaf-spring bushings, worn shackles, loose tie-rods, or steering gear play.
5. Steering knuckle bushings on a kingpin front axle should be beaten in and out with a broad hammer. If the edges peen over, just straighten them out with a course file.
6. The idler arm on A-arm front suspension moves in unison with the pitman arm. The idler arm mounts to the right framerail. This is a common wear item.
7. Cutting coil springs changes ride height. It also alters the camber angle of the front wheels. If you lower a truck by this method, there will be less suspension travel.
8. If you need to remove a tie-rod end, beat on the end of the ball stud. This will knock the ball stud loose without damaging any parts.
9. Chevrolet and GMC light trucks first used independent front suspension in 1952. The trucks of the '50s benefited from this design.
10. Steering linkage on kingpin front axles is simpler and has less tie-rod ends than double A-arm front suspension. Ford's twin I-beam uses simpler steering linkage as well.
