CAUTION: If a steering gear assemb ly is returned under warranty with leaking seals, but there is also
damage to the steering gear boot/boots the steering gear warranty will be invalid. This is due to the steering
gear seals being damaged due to fore ign materials entering the steering gear boot and damaging the steering
gear seals thereafter.

Description of Specific St eer
ing System Noise Types
Bel
t Squeal
Belt squea
l is a high frequency air-born
e noise generated by slippage of the ribbe d Vee belt on the power steering pump
pulley. Squeal increases with system loading and at the end of lock.
Clonk

Cl
onk is a structure-borne nois
e heard as a loose-sounding rattle or vibration coming from the steering column. Clonk can
be identified by driving and turning over cobblestones, rough roads, or high frequency bumps such as 25-50 mm tall tar
strips. Clonk requires a tie-rod load impact.
Column Knoc
k
Col
umn knock is a loose-sounding rattle or
vibration generated by the steering column shaft contacting other portions of the
column assembly. The noise is both audible and tactile. Column knock is generate d by driving over cobblestones or rough
pavement. It is not necessary to turn the steering wheel to create this noise.
Column Ra
ttle
Co
lumn rattle is a metallic sounding no
ise created when applying a highly impuls ive force to the steering wheel. Column
rattle is often used to combine the more general group of column noises includin g clonk and column knock. Column rattle
noises can be caused by clonk, knock, l oose column components, bonus parts etc. A series of parked, straight-line driving,
and cornering test should be carried out to isolate the source/sources.
Gr
inding/Scrape
Gr

inding is a low frequency noise in the column when the st
eering wheel is turned. Is generally caused by interference
between moving components such as the st eering wheel to steering column shroud.
Gr
unt (Squawk)
Grunt

is a "honking" sound elicited when coming off one of
the steering stops. Grunt is generally excited during parking
manoeuvres with a low to me dium speed steering input.
