Exam 46: Suspension Systems

In what type of leaf spring is the center of the spring mounted to the vehicle's chassis and the outer ends fastened to the ends of the axle housing or wheel spindles?

To reduce noise and friction, multileaf springs have interleaves of zinc and ____________________ placed between the spring's leaves.

The core of any suspension system is the ______.

A technician is checking a suspension complaint. He depresses the front bumper a few inches by hand then releases it. When the front bumper is released, it oscillates up and down about three times before coming to rest. What could be the problem?

What is the first step in diagnosing a suspension system concern?

Technician A says a weak suspension spring can affect the wheel alignment. Technician B says a weak suspension spring can cause poor braking. Who is correct?

Shock absorbers dampen spring movement rather than absorb shock.

Semi-independent suspensions are used on the rear of many front-wheel drive cars.

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

Which of the following is not a type of leaf spring?

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

Springs are rubber mounted to reduce road shock and noise.

Strut designs are being discussed. Technician A says in the conventional MacPherson strut, the coil spring surrounds the upper part of the strut. Technician B says in the modified MacPherson strut, the coil spring is located between the control arm and frame/unibody. Who is correct?

Describe the major difference between conventional frame construction and unibody construction.

A variable rate spring design that has a cylindrical shape with unequally spaced coils is called a(n)____________________ rate coil spring.

Identify some ride characteristics gained from using fiber composite springs.

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

Technician A says periodic adjustment of the torsion bars is necessary to maintain the proper ride height. Technician B says torsion bars are interchangeable from side to side. Who is correct?

Electronically controlled suspensions are ______ systems.

Torsion bar suspension is usually found on ______.
