Checking for Refrigerant LeaksEJS0020U
Perform a visual inspection of all refrigeration parts, fittings, hoses and components for signs of A/C lubricant
leakage, damage and corrosion. A/C lubricant leakage may indicate an area of refrigerant leakage. Allow
extra inspection time in these areas when using either an electronic refrigerant leak detector or fluorescent
dye leak detector.
If dye is observed, confirm the leak with an electronic refrigerant leak detector. It is possible a prior leak was
repaired and not properly cleaned.
When searching for leaks, do not stop when one leak is found but continue to check for additional leaks at all
system components and connections.
When searching for refrigerant leaks using an electronic leak detector, move the probe along the suspected
leak area at 1 to 2 inches per second and no further than 1/4 inch from the component.
CAUTION:
Moving the electronic leak detector probe slower and closer to the suspected leak area will improve
the chances of finding a leak.
Checking System for Leaks Using the Fluorescent Leak DetectorEJS0020V
1. Check A/C system for leaks using the UV lamp and safety glasses (J-42220) in a low sunlight area (area
without windows preferable). Illuminate all components, fittings and lines. The dye will appear as a bright
green/yellow area at the point of leakage. Fluorescent dye observed at the evaporator drain opening indi-
cates an evaporator core assembly (tubes, core or expansion valve) leak.
2. If the suspected area is difficult to see, use an adjustable mirror or wipe the area with a clean shop rag or
cloth, with the UV lamp for dye residue.
3. After the leak is repaired, remove any residual dye using dye cleaner (J-43872) to prevent future misdiag-
nosis.
4. Perform a system performance check and verify the leak repair with an approved electronic refrigerant
leak detector.
NOTE:
Other gases in the work area or substances on the A/C components, for example, anti-freeze, windshield
washer fluid, solvents and lubricants, may falsely trigger the leak detector. Make sure the surfaces to be
checked are clean.
Clean with a dry cloth or blow off with shop air.
Do not allow the sensor tip of the detector to contact with any substance. This can also cause false readings
and may damage the detector.

REMOVALNJSU0031S01CAUTION:
Before removing the rear suspension assembly, disconnect
the ABS wheel sensor from the assembly. Failure to do so may
result in damage to the sensor wires and the sensor becom-
ing inoperative.
Remove suspension assembly.
1. Disconnect parking brake cable from caliper and remove brake
caliper and rotor.
Suspend caliper assembly with wire so as not to stretch
brake hose.
Be careful not to depress brake pedal, or piston will pop
out.
Make sure brake hose is not twisted.
2. Using a transmission jack, raise torsion beam a little, and
remove nuts and bolts from the trailing arm, shock absorber
assembly (lower side) and lateral link (Body side).
3. Lower transmission jack, and remove suspension.
4. Remove strut securing nuts (upper side). Then pull out strut
assembly.

INSTALLATIONNJSU0031S02Install suspension assembly.
CAUTION:
Refill with new brake fluid “DOT 4”.
Never reuse drained brake fluid.
1. Attach torsion beam, at trailing arm and lateral link, to vehicle.
Do not tighten bolts at this time.
SRA698A
2. Using a transmission jack, place lateral link and control rod
horizontally against torsion beam. Tighten lateral link on
vehicle.
3. Attach shock absorber assembly to vehicle. Then tighten the
lower side of shock absorber assembly.
4. Lower torsion beam to fully extended position. Remove trans-
mission jack and tighten torsion beam, at trailing arm, to speci-
fied torque. Refer to SU-20.
5. Install brake caliper and rotor, then connect parking brake
cable to caliper.
6. Install ABS wheel sensor.
