All the following are typical automotive suspension system problems EXCEPT:

• bad control arm bushings

• damaged flex plate

• fatigued (weakened) suspension springs

• bad ball joints

A vehicle’s body bounces five times after a shock absorber bounce test is performed. Technician A says this indicates that the shock absorbers are in good condition. Technician B says the results of this test indicate bad shock absorbers. Who is right?

. A vehicle’s curb weight is being measured. Technician A checks curb weight with the vehicle’s gas tank empty. Technician B says adhering to the vehicle’s manufacturer-specified curb weight is unnecessary when trying to take an accurate measurement of the vehicle’s curb height. Who is right?

A full-size pickup truck’s coil springs are being replaced. During this procedure, Technician A unbolts the ball joint on the control arm before compressing the coil spring. Technician B says that a new larger coil spring that fits outside of the spring seats can be safely installed to improve vehicle ride quality. Who is right?

• Both

• Neither

Technician A says leaf spring service often involves spring assembly or bushing replacement. Technician B says leaf springs are used in many late-model pickup trucks because they cannot break. Who is right?

A vehicle is brought into the shop with a possible ball joint problem. Technician A says if the ball joint is dry, it has collapsed inward and will feel hard to the touch because of a lack of grease. Technician B jacks up the vehicle, moves the control arm and joint with a long pry bar, and checks the movement and play against manufacturer specifications to check if the ball joint is worn. Who is right?

• A

• B

• Both

• Neither

The fastening of most modern ball joints with the vehicle’s suspension components is accomplished with:

• epoxy glue

• snap rings

• a press-fit method

• All of the above

A vehicle’s front tires are worn. Technician A tells the vehicle owner that worn control arm bushings may have caused this problem. Technician B tells the owner that stiction between suspension rubber bushings and metal parts must be maximized for the best system performance. Who is right?
