DIAGNOSTIC INFORMATION AND PROCEDURES
SQUEAK AND RATTLE DIAGNOSIS
ConditionProbable CauseCorrection
Rattle Coming From the
Side Rail
Improperly connected brake
lines.
Tap lightly on the brake lines and listen for a
rattle.

Install plastic tie straps to secure the brake
lines tightly together.
Rattle Under Vehicle at
Higher RPM
The heat shield contacts with
the underbody.
Raise the vehicle and perform a visual
inspection.

Bend the heat shield slightly to gain
clearance from the underbody.
Squeak From the Front
of the Vehicle in Cold
Weather
Poor front stabilizer shaft
insulators taping.
While the vehicle is cold, perform a test drive
and achieve full front suspension travel by
driving through a dip in the road.

Remove the insulators and wrap teflon tape
around the stabilizer shaft. Reinstall the
insulators over the tape.
Thump From Rear of
Vehicle on Bumps
Improperly secured spare tire in
the rear compartment.
Open the rear compartment and perform a
visual inspection of the spare tire and the
tools.

Tightly secure the spare tire and all tools.

Perform a road test to verify that the noise is
eliminated.
Glass Knock Coming
From the Rear of the
Vehicle When Driving
Over Bumps
An out-of-adjustment hatchback
latch.
Test drive the vehicle in order to verify this
condition.

Loosen the latch nuts and adjust the latch
downward.
Rattle Coming From
Door
The door lock solenoid is loose.
Remove the door trim panel and check if the
solenoid is loose.

Tighten the solenoid bolts.

Rattling electrical connectors
inside the door trim panel.
Tap on the trim panel and listen for a rattle.

Remove the trim panel and wrap foam
padding around the connectors as required.
Squeak When
Operating Doors
A lack of lubrication of the door
hinge pins.
Operate the doors and listen for squeaks.

Lubricate the door hinge pins with light oil
and coat with lithium grease.

A lack of lubrication of the door
hold open link arm.
Lubricate the door hold open link arm with
light oil and coat with lithium grease.
