A mid-
range frequency (200- 800 Hz) noise between drumming and whine. Also described as a hum.
Hum
Mid- frequency (200- 800 Hz) steady sound, like a small fan motor. Also described as a howl.
Hz
Hertz; a frequency measured in cycles per second.
Imbalance
Out of balance; heavier on one side than the other. In a rotating component, imbalance often causes
vibration.
Inboard
Toward the centerline of the vehicle.
Intensity
The physical quality of sound that relates to the strength of the vibration (measured in decibels). The
higher the sound's amplitude, the higher the intensity and vice versa.
Isolate
To separate the influence of one component to another.
Knock
A heavy, loud, repetitious sound, like a knock on the door.
Moan
A constant, low- frequency (100-200 Hz) tone. Also described as a hum.
Neutral Engine Run- Up (NERU) Test
The operation of the engine through the normal rpm range with the vehicle standing still and the
transmission disengaged. This test is used to identify engine related vibrations.
Neutralize/Normalize
To return to an unstressed position. Used to describe mounts. Refer to Bound Up.
Outboard
Away from the centerline of the vehicle.
Ping
A short duration, high- frequency sound, which has a slight echo. Klj . 7 ba

Lateral runout means measuring the movement or "wobble" of a wheel or tire at the sidewall. Radial
runout means measuring the out-of-
round at the tread surface.
Rustling
Intermittent sound of varying frequency (100- 2000 Hz), sounds similar to shuffling through leaves.
Shake
A low- frequency vibration (5-20 Hz), usually with visible component movement. Usually relates to tires,
wheels, brake drums or brake discs if it is vehicle speed sensitive, or engine if it is engine speed
sensitive. Also referred to as a shimmy or wobble.
Shimmy
An abnormal vibration or wobbling, felt as a side- to-side motion of the steering wheel in the driveshaft
rotation. Also described as waddle.
Shudder
A low- frequency vibration that is felt through the steering wheel or seat during light brake application.
Slap
A resonance from flat surfaces, such as safety belt webbing or door trim panels.
Slip Yoke/Slip Spline
The driveshaft coupling that allows length changes to occur while the suspension articulates and while
the driveshaft rotates.
Squeak
A high- pitched transient sound, similar to rubbing fingers against a clean window.
Squeal
A long- duration, high- pitched noise.
Static Balance
The equal distribution of weight around the wheel. Statically unbalanced wheel and tire assemblies can
cause a bouncing action called wheel tramp. This condition will eventually cause uneven tire wear.
Tap
A light, rhythmic, or intermittent hammering sound, similar to tapping a pencil on a table edge.
Thump
A dull beat caused by two items striking together. Tick Klj . 9 ba

and evaporative emission noises. The Ultrasonic Leak Detector includes a multi-
directional transmitter
(operating in the ultrasonic range) and a hand- held detector. The transmitter is placed inside the
vehicle. On the outside of the vehicle, the hand- held detector is used to sweep the area of the
suspected leak. As the source of the leak is approached, a beeping sound is produced which
increases in both speed and frequency.
Squeak and Rattle Repair Kit
The squeak and rattle repair kit (Rotunda tool number 164- R4900) contains lubricants and self-
adhesive materials that can be used to eliminate interior and exterior squeaks and rattles. The kit
consists of the following materials:
zPVC (soft foam) tape
z Urethane (hard foam) tape
z Flocked (black fuzzy) tape
z UHMW (frosted) tape
z Squeak and rattle oil tube
z Squeak and rattle grease tube
Tracing Powder
Tracing powder is used to check both the uniformity of contact and the tension of a seal against its
sealing surface. These tests are usually done when a suspected air leak/noise appears to originate
from the seal area or during the alignment and adjustment of a component to a weatherstrip. Tracing
powder can be ordered from Crest Industries as ATR Leak Trace. Carry out the tracing powder test as
follows:
a. Clean the weatherstrip.
b. Spray the tracing powder on the mating surface only. c. Close the door completely. Do not slam the door.
d. Open the door. An imprint is made where the weatherstrip contacted the mating surface seal. Gaps or a faint imprint will show where there is poor contact with the weatherstrip. Klj . 13 ba

Index Card
Place an index card or a piece of paper between the weatherstrip and the sealing surface, then close
the door. Slowly withdraw the index card or paper after the door is closed and check the amount of
pressure on the weatherstrip. There should be a medium amount of resistance as it is withdrawn.
Continue around the entire seal area. If there is little or no resistance, this indicates insufficient contact
to form a good seal. At these points, the door, the glass, or the weatherstrip is out of alignment. Klj . 14 ba
