ROLLOVER VALVE(S)

Two rollover valves are used. One of the valves is

permanently mounted to top/rear of fuel tank (Fig.
23). If replacement of this particular valve is neces-
sary, the fuel tank must be replaced. Refer to Fuel
Tank Removal/Installation in Group 14, Fuel System.
The other rollover valve is located on top of the fuel
pump module (Fig. 23). This valve may be serviced
separately. Refer to following steps for procedures.

REMOVAL

WARNING: THE FUEL SYSTEM IS UNDER A CON-
STANT PRESSURE (EVEN WITH THE ENGINE OFF).
BEFORE SERVICING THE ROLLOVER VALVE(S),
FUEL SYSTEM PRESSURE MUST BE RELEASED.
REFER TO FUEL PRESSURE RELEASE PROCE-
DURE IN GROUP 14, FUEL SYSTEM.

(1) Disconnect negative battery cable at battery.
(2) Remove fuel filler cap and drain fuel tank.
(3) Remove fuel tank. Refer to Fuel Tank Removal/

Installation in Group 14, Fuel System.

(4) Disconnect tube (line) at valve.
(5) The rollover valve is seated into a rubber grom-

met. Remove valve by prying one side upward and
then roll valve out of grommet.

(6) Discard old grommet.

INSTALLATION

(1) Install new grommet into fuel pump module.
(2) Using finger pressure only, press valve into

place.

(3) Install fuel tank. Refer to Fuel Tank Installa-

tion.

(4) Fill fuel tank. Install fuel tank filler cap.
(5) Connect negative battery cable.
(6) Start vehicle and check for leaks.

LEAK DETECTION PUMP (LDP)

The LDP is located in the engine compartment

under the battery tray and Power Distribution Cen-
ter (PDC) (Fig. 24). The LDP filter is attached to the
outside of battery tray (Fig. 25). The LDP and LDP
filter are replaced (serviced) as one unit.

REMOVAL

(1) Disconnect negative battery cable at battery.
(2) Remove battery. Refer to Group 8A, Battery for

procedures.

(3) Carefully disconnect rubber hose from bottom

of LDP filter (Fig. 25).

(4) Remove clip retaining LDP filter to battery

tray (Fig. 25) and remove filter from tray.

(5) Disconnect battery temperature sensor pigtail

wiring harness at bottom of battery tray.

(6) To gain access to LDP, the PDC must be par-

tially removed. Remove PDC-to-fender mounting
screw at rear of PDC. Unsnap PDC from battery
tray. To prevent damage to PDC wiring, carefully
position PDC to gain access to LDP.

REMOVAL AND INSTALLATION (Continued)

(10) Remove 3 LDP mounting screws (Fig. 26) and

remove LDP from vehicle.

INSTALLATION

(1) Install LDP to bottom of battery tray. Tighten

screws to 1 N·m (11 in. lbs.) torque.

(2) Carefully install vapor/vacuum lines to LDP.

The vapor/vacuum lines and hoses must be
firmly

connected.

Check

the

vapor/vacuum

lines at the LDP, LDP filter and EVAP canister
purge solenoid for damage or leaks. If a leak is
present, a Diagnostic Trouble Code (DTC) may
be set.

(3) Connect electrical connector to LDP.
(4) Install battery tray. Refer to Group 8A, Battery

for procedures.

(5) Install PDC to fender and battery tray (snaps

on to battery tray).

(6) Install LDP filter to battery tray (one clip).
(7) Install connecting hose to bottom of LDP filter.
(8) Connect battery temperature sensor pigtail

wiring harness.

(9) Install battery. Refer to Group 8A, Battery for

procedures.

(10) Connect negative battery cable to battery.

DESCRIPTION AND OPERATION

PROPELLER SHAFT

DESCRIPTION

A propeller shaft (Fig. 2), (Fig. 3), and (Fig. 4) is

the shaft which connects the transmission/transfer
case to the axle differential. This is the link through
which the engine power is transmitted to the axle.

The propeller shaft is designed and built with the

yoke lugs in line with each other which is called zero
phasing. This design produces the smoothest running
condition, an out-of-phase shaft can cause a vibra-
tion.

Tubular propeller shafts are balanced by the man-

ufacturer with weights spot welded to the tube.

PRECAUTIONS

Use the exact replacement parts when installing

the propeller shafts. The use of the correct replace-
ment parts helps to ensure safe operation. All fasten-
ers must be torqued to the specified values for safe
operation.

Also make alignment reference marks (Fig. 1) on

the propeller shaft yoke and axle, or transmission,
yoke prior to servicing. This helps to eliminate possi-
ble vibration.

CAUTION: Do not allow the propeller shaft to drop
or hang from any propeller shaft joint during
removal. Attach the propeller shaft to the vehicle
underside with wire to prevent damage to the joints.
