Clunk

Clunk is a metallic noise heard when the automatic transmission is engaged in REVERSE or DRIVE. The noise may also occur
when the throttle is applied or released. Clunk is caused by transmission calibration, backlash in the driveline or loose
suspension components and is felt or heard in the vicinity of the rear drive axle.

Bearing Rumble

Bearing rumble sounds like marbles being tumbled. This condition is usually caused by a worn/damaged wheel bearing. The
lower pitch is because the wheel bearing turns at only about one-third of the driveshaft speed. Wheel bearing noise also may
be high-pitched, similar to gear noise, but will be evident in all four driving modes.

Steering Linkage Inspection and Backlash (Free play) Check


CAUTION: Steering gear boots must be handled carefully to avoid damage. Use new clamps when installing steering gear
boots.

Inspect the boots for cuts, deterioration, twisting or distortion. Check the steering gear boots to make sure they are tight.
Install new boots or clamps as required.


NOTE: The following steps must be carried out with assistance.

1. With the wheels in the straight ahead position, gently turn the steering wheel to the left and the right to check for free
play.

between moving components such as the steering wheel to steering column shroud.

Grunt (Squawk/Whoop)

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 medium speed steering input.

Hiss (Swish)

Hiss or Valve Hiss is a high-frequency sound coming from the steering gear when the system is loaded. It is a rushing or
'swish' noise that doesn't change frequency with RPM. Hiss is the general noise generated by the flow of hydraulic fluid through
restrictions in the steering system. Restrictions include the rotary steering valve, power steering tubes, connectors, tuning
orifices, etc. Hiss can be air-borne and structure-borne, but the structure-borne path through the steering intermediate shaft is
usually dominant.

Moan (Groan)

Moan is the general structure-borne noise of the steering system. Moan is primarily transmitted to the driver via the body
structure through the pump mount, engine mounts, power steering lines and power steering brackets. On some vehicles, moan
is a loud humming noise, often present when the wheel is turned and the system is loaded. It may change frequency with
engine RPM and if the system is loaded or unloaded.

Steering Gear Knock (Steering Gear Slap)


CAUTION: DO NOT attempt to adjust the steering gear yoke. Failure to follow this instruction will invalidate the steering
gear warranty.

Steering gear knock is a rattle sound and steering wheel vibration caused by separation of the steering gear and pinion while
driving over bumps. It is a structure-borne noise transmitted through the intermediate shaft and column. Steering gear knock
can also be heard as a 'thump' or impact noise that occurs with the vehicle stationary when the steering wheel is released
from a loaded position and allowed to return to rest. Noise occurs with the engine on or off.

Rattles

Rattles are noises caused by knocking or hitting of components in the steering system. Steering rattles can occur in the engine
compartment, the suspension, or the passenger compartment. Rattles can be caused by loose components, movable and
flexible components, and improper clearances.

Squeaks/Scrapes

Squeaks/Scrapes are noises due to friction or component rubbing anywhere in the steering system. Squeaks/Scrapes have
appeared in steering linkages and joints, in column components and in column and steering wheel trim.

Weep

Weep is an air-borne noise, occasionally generated when turning the steering across lock at a constant rate. When present on
a vehicle the noise, once initiated can often be maintained across a large proportion of the available steering movement.

Whistle

Whistle is similar to hiss but is louder and of a higher frequency. It is also more of a pure tone noise than hiss. Whistle is
air-borne and is generated by a high flow rate of hydraulic fluid through a small restriction.

Zip

Zip noise is the air-borne noise generated by power steering pump cavitation when power steering fluid does not flow freely
through the suction hose from the reservoir to the pump. Zip primarily occurs during cold weather at start-up.

Steering System Vibrations and Harshness
Buzz
Buzz is a tactile rotary vibration felt in the steering wheel when steering inputs are slow. Buzz can also be called a grinding
feel and it is closely related to grunt and is caused by high system gain with low damping. Buzz is generally excited during
parking manoeuvres with low to medium speed steering input.

Buzz (Electrical)

A different steering buzz can be caused by pulse width modulated (PWM) electric actuators used in variable assist steering
systems. This buzz is felt by turning the ignition key to run without starting the engine and holding onto the steering wheel.
In extreme cases, the buzz can be felt with the engine running also.

Column/Steering Wheel Shake

Column shake is a low frequency vertical vibration excited by primary engine vibrations.

Underbody sealer

Under floor areas and the front part of the spare wheel well are treated with a plastisol PVC underbody sealer. This material is
not suitable for re-treatment. When repairing areas of underbody sealer, strip the factory-applied underbody sealer back to a
suitable break point. Ensure that a clean metal surface is exposed and that the edge of the existing adheres soundly to the
panel.

Apply new underbody sealer between primer and surface paint operations. Apply seam sealer as necessary before application
of underbody sealer. Ensure that blanking plugs and grommets in the floor pan (except those used for wax injection) are fitted
before underbody sealer application. Refit any heat-fusible plugs which have been disturbed in repair with the aid of a hot air
blower, or replace with rubber grommets


CAUTION: Ensure that suspension units, wheels, tires, power unit, drive shafts, exhaust and brakes, (including all
mounting points), are shielded prior to application of fresh underbody sealer. www.JagDocs.com
