SQUEAK AND RATTLE REPAIR

Squeaks and rattles are caused by the unwanted move-
ment between parts of a vehicle. There are threemeans to
prevent squeaks or rattles.

S

 

Attach the parts securely so that there is no relative
motion during the operation of the vehicle.

S

 

Separate the parts so that there is no contact dur-
ing operation.

S

 

Insulate the parts so that no squeaks or rattles oc-
cur with the movement of the parts. Low uniform
friction surfaces can be used to eliminate ”stick–
slip” motion.

DIAGNOSIS

WATERLEAK DIAGNOSIS

The repair of waterleaks in the body requires proper test-
ing and diagnosis. Repair waterleaks by adjusting the mis-
aligned parts and using the proper repair materials. First,
determine what conditions cause the leak. For example,
the leak may occur only when the vehicle is parked on an
incline, or water may appear only in the spare tire compart-
ment. Second, test the area for the source of the leak us-
ing the following testing methods. If the general leak area
is found, determine the exact entry point of the leak by us-
ing a water hose or an air hose. If the general leak area is
not obvious, use the watertest stands to determine the
area of the leak. It may be necessary to remove some inte-
rior trim panels or some parts in order to locate the leaks.

Important :  It is necessary to find the origin of all the leaks
before making any repairs. Random repairs may stop the
leak only temporarily and may make future repairs more
difficult. Continue localized testing in the general area in
order to ensure that all leaks are found.

Generalized Testing

1.  Set up the watertest stands.

1)

1/2–inch by 36–inch Pipe

2)

Full–jet Spray Nozzle #1/2 GG–25 or Equiva-
lent Nozzle Height at 1,600 mm to the Floor

3)

1/2–inch Coupling

4)

1/2–inch by 1/2–inch by 1/4–inch Reducing T
(Right Only)

5)

1/2–inch Coupling (Left Only)

6)

1/2–inch Cross (Right Only)

7)

1/2–inch Tee (Left Only)

8)

5/8–inch Input Hose (2 Feet Long, Right Only)

9)

1/2–inch Pipe–to–Hose Nipple (Right Only)

10) 1/2–inch Close Nipple
11) 1/2–inch Cross with Weld–on 1/2–inch Cap
12) 1/2–inch by 12–inch Nipple
13) 1/2–inch Cap
14) 5/8–inch Female Hose Coupling
15) 5/8–inch Cross Hose (12 Feet Long)
16) 5/8–inch Hose Quick Connect
17) 1/2–inch Pipe–to–Hose Nipple
18) 1/2–inch by 30–inch Pipe (Straight)
19) 1/4–inch Water Pressure Gauge (Right Only)

2.  Set up the watertest stand leak test.

3.  Perform the watertest stand leak test. Refer to”Wa-

tertest Stand Specifications”  in this section.

4.  If the local water pressure does not allow the re-

quired water pressure of 155 kPa (22.5 psi), move
both stands closer to the vehicle so that the water
spray overlaps.

Localized Testing (Spot Test)

1.  Do localized testing with a water hose or an air

hose.

2.  Begin testing by spraying the air or the water at the

base of the suspected leak area. Continue spraying
the air or the water upward until the leak is found.

Water Hose Test

1.  Place another person inside the vehicle in order to

detect the location of the leak.

2.  Use a water hose without a nozzle.

3.  Begin spraying the water at the base of the sus-

pected leak area. Continue spraying the water up-
ward until the leak is found.
