Steering and Suspension

Technician A says a worn or damaged idler arm can cause front-end shimmy. Technician B says a worn or damaged idler arm can cause hard steering. Who is correct?

Technician A says to avoid using heat on any part of the steering linkage, Technician B says if parts must be heated in order to remove them, the parts must be replaced. Who is correct?

Rack-and-pinion steering systems are being discussed. Technician A says they require two outer tie-rod ends . Technician B says they do not require inner tie-rod ends. Who is correct?

Which of the following tire wear patterns will result from excessive negative camber?

What direction must the top of a tire and wheel assembly be moved to add more positive camber?

Torqueing lug nuts beyond specifications may distort the disc brake rotor.

Adjustable air shocks can be manually filled

Shock absorbers are always mounted vertically, not at an angle.

Springs absorb wheel jounce and rebound.

The faster a shock absorber moves, the more resistance it has to the movement.

Springs are rubber mounted to reduce road shock and noise.

Torsion bars operate on a twisting motion.

In a rack-and-pinion steering system, the rack is the steering input and drives the pinion in order to move the wheels.

The front-wheel suspension design greatly influences steering geometry.

Parallelogram steering arrangements typically use a rack-and-pinion mechanism.
