SQUEAK AND RATTLE TROUBLE DIAGNOSES

SE-23

< SYMPTOM DIAGNOSIS >

SEATS

When isolating seat noise it is important to note the position the seat is 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.

Causes 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 motor wall. The noise is then

transmitted into the passenger compartment.

Causes of transmitted underhood noise include:
1. Any component mounted to the motor wall
2. Components that pass through the motor wall
3. Motor 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, motor 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.
