< SYMPTOM DIAGNOSIS >
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 c an 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 is important to note t he position the seat is in and the load placed on the seat
when the noise is present. 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. 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 thes e 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.

DRIVE PINION
7. Using drift [SST: ST33200000 (J-26082)], press the pinion front
bearing inner race to drive pinion as far as drive pinion nut can
be tightened.
8. Install front oil seal as shown in figure with the drifts (A and B). CAUTION:
 Never reuse oil seal.
 When installing, n ever incline oil seal.
 Apply multi-purpose grease onto oil seal lips, and gear oil
onto the circumference of oil seal.
9. Install companion flange (1). NOTE:
When reusing drive pinion, align the matching mark (B) of drive
pinion with the matching mark (A) of companion flange, and then
install companion flange (1).
10. Temporarily tighten drive pinion lock nut to drive pinion. CAUTION:
 Apply anti-corrosion oil to th e thread and seat of the drive
pinion lock nut
 Never reuse drive pinion lock nut.
11. Tighten to drive pinion lock nut using flange wrench (A), while adjusting pinion bearing preload torque using preload gauge (B).
CAUTION:
 Adjust to the lower limit of the drive pinion lock nut tight-
ening torque first.
 After adjustment, rotate dri ve pinion back and forth 2 to 3
times to check for unusual no ise, rotation malfunction,
and other malfunctions.
12. Install differential case assembly. Refer to DLN-169, "
Assem-
bly".
