An alternate procedure to inspect steering linkage for looseness is called:
steering link check
steering movement check
dry park check
lock-to-lock check

, 41. The correct answer is B. Retorquing a short time after installation (50 to 100 miles)
to ensure full seating is important. Retorquing at an appropriate interval even when
wheels are not removed is also an important adjunct to operating safety. Consult
the manufacturer for torque specifictions and procedures and retorquing mileage
intervals.
64. The correct answer is A. The kingpin or knucklepin secures the steering knuckle
to the axle. It can be either tapered or straight, depending on the manufacturer.
Inspection and lubrication of the kingpin must be performed in accordance with the
manufacturer's recommended service procedures.
69. The correct answer is C. The steering linkage can also be inspected using
a procedure called a dry park check.' With the engine off, have an assistant
rotate the steering wheel from side-to-side while you inspect the steering
linkage joints for looseness. Any side-to-side movement of the steering
linkage joints is cause for
replacement.
62. The correct answer is D, neither technician is right. Since toe-in is
affected by caster and camber, it should be the last adjustment made. Toe-in is the
amount that the front of the front wheels are closer together than they are at the
back of the
front wheels.

28. The vehicle's suspension system must do all of the
following EXCEPT:
,A. support the load
B.articulate the load (that is, maintain alignment during up-and-down
motion)
C. remove excess energy that otherwise becomes stored up in
the springs and prevents smooth ride
D.provide a rigid foundation for frame or trailer support

21. The correct answer is B. Tread wear is uneven on tandem drive axles for
two reasons: First, the distribution of power is not perfectly equal between all the
wheel positions and rotation will equal out the variations. Second, when a tandem
axle
tractor takes a corner, the forward axle's tires scrub a bit more than those on the
rear axle; rotation equalizes this wear, too.
28. The correct answer is D. The suspension system is, by nature, not rigid, as a
rigid system would transfer all the energy generated as the wheels run over
bumps to the frame and the load. Even systems designed to support extreme
loads at least incorporate rubber cushioning. The system must obviously
support the load, keep the vehicle's axles and frame in appropriate
alignment for safe steering and level support, and remove excess energy
(with shock
absorbers)
22. The correct answer is C. This is because this sum gives the relationship
between the centerline of the wheel and the centerline of the kingpin (or knuckle
support pivots with lighter duty type front axles). This angle is built into the
knuckle forging and remains constant unless the spindle is damaged during use.
Toe-in and caster do not have any effect on this angle.
2. The correct answer is C, both technicians are right. Either a worn shackle
bushing or worn shock bushing can cause noise due to looseness when the truck
hits a good bump. If there is clearance between the rubber bushing and mounting
, bolt,
