SQUEAK AND RATTLE TROUBLE DIAGNOSES

Most of these incidents can be repaired by adjusting, securing or insulating the item(s) or component(s) caus-
ing the noise.

SUNROOF/HEADLINING

Noises in the sunroof/headlining area can often be traced to one of the following:

1.

Sunroof lid, rail, linkage or seals making a rattle or light knocking noise

2.

Sunvisor shaft shaking in the holder

3.

Front or rear windshield touching headlining and squeaking

Again, pressing on the components to stop the noise while duplicating the conditions can isolate most of these
incidents. Repairs usually consist of insulating with felt cloth tape.

SEATS

When isolating seat noise it's important to note the position the seats in and the load placed on the seat when
the noise occurs. These conditions should be duplicated when verifying and isolating the cause of the noise.
Cause of seat noise include:

1.

Headrest rods and holder

2.

A squeak between the seat pad cushion and frame

3.

The rear seatback lock and bracket

These noises can be isolated by moving or pressing on the suspected components while duplicating the con-
ditions under which the noise occurs.Most of these incidents can be repaired by repositioning the component
or applying urethane tape to the contact area.

UNDERHOOD

Some interior noise may be caused by components under the hood or on the engine wall. The noise is then
transmitted into the passenger compartment.
Causes of transmitted underhood noise include:

1.

Any component mounted to the engine wall

2.

Components that pass through the engine wall

3.

Engine wall mounts and connectors

4.

Loose radiator mounting pins

5.

Hood bumpers out of adjustment

6.

Hood striker out of adjustment

These noises can be difficult to isolate since they cannot be reached from the interior of the vehicle. The best
method is to secure, move or insulate one component at a time and test drive the vehicle. Also, engine RPM
or load can be changed to isolate the noise. Repairs can usually be made by moving, adjusting, securing, or
insulating the component causing the noise.
