Exam 46: Suspension Systems

Variable rate springs handle a load of up to 30 percent over standard rate springs in some applications.

How does a stabilizer bar work?

The ____________________ spring design uses only a single leaf.

Adjustable air shocks can be manually filled.

Technician A says the shackle prevents fore and aft movement of a leaf spring. Technician B says most leaf springs are semi-elliptical. Who is correct?

The ____________________ bar provides directional stability by reducing body roll.

What is the purpose of an air shock system?

A weak spring will NOT cause _____.

The simplest types of electronically controlled suspension systems are automatic level control systems that use electronic height sensors to control an air compressor linked to ____________________ shock absorbers.

Control arms are attached to the frame of the vehicle with ____________________ elastomeric bushings.

Ball joints are being discussed. Technician A says a load-carrying ball joint supports the car's weight and is generally found on the control arm that the spring rests on. Technician B says all ball joints require periodic lubrication. Who is correct?

Suspension bushings are being discussed. Technician A says the rubber bushings used in a control arm flex and twist as the control arm moves up and down. Technician B says rubber bushings should be lubricated with petroleum-based lubricants every 30,000 miles. Who is correct?

A short-long arm suspension system is also called a(n) ____________________ length arm suspension system.

The ____________________ bar provides directional stability by reducing body roll.

Which of the following would NOT cause rattling noise on road irregularities?

Springs carry the weight of the vehicle and absorb shock forces.

The most advanced computer-controlled suspension systems are true active suspensions. They use high-pressure _____ actuators to carry the vehicle's weight rather than conventional springs or air springs.

Technician A says a typical car shock has more resistance during compression [jounce]. Technician B says mounting shock absorbers at an angle improves vehicle stability and dampens accelerating and braking torque. Who is correct?

Vehicle height is checked with the fuel tank ______.

Identify three tasks that an independent front wheel suspension system must perform.
