STEERING GEAR INPUT SHAFT SEAL
REMOVAL
1. Remove the steering gear from the vehicle(Referto19-STEERING/GEAR-REMOVAL).
CAUTION: Do not overtighten the vise on the gear case. This may affect the adjustment
2. Mount the steering gear upside down over a drain pan in a soft jawed vise.
3. Place a drain pan under the gear and rotate the input shaft back and forth several times lock-to-lock to discharge
the fluid from the steering gear
4. Drain all the remaining fluid from the gear.
5. Rotate the input shaft (4) from stop to stop and
count the number of turns using a 12 point socket
(2).
NOTE: The pitman shaft will not clear the housing
if it is not centered.
6. Center the input shaft (4) by rotating it from the
stop back 1 1/2 turns to achieve center position.

POWER STEERING PUMP - INITIAL OPERATION
WARNING: THE FLUID LEVEL SHOULD BE CHECKED WITH ENGINE OFF TO PREVENT INJURYFROMMOV-
ING COMPONENTS.
CAUTION: MOPAR
ATF+4 is to be used in the power steering system. No other power steering or auto-
matic transmission fluid is to be used in the system. Damage may result to the power steering pump and
system if any other fluid is used, and do not overfill.
Wipe filler cap clean, then check the fluid level. The dipstick should indicateCOLDwhen the fluid is at normal
temperature.
1. Turn steering wheel all the way to the left.
2. Fill reservoir up to FULL HOT level and crank engine until it just starts.(DO NOT TURN STEERING WHEEL).
Then turn vehicle off. And recheck fluid level, to Full COLD.
3. Crank engine again until it just starts, (DO NOT MOVE STEERING WHEEL). and turn vehicle off. Recheck fluid
leveltoFullCOLD.
4. Turn engine on again, (DO NOT MOVE STEERING WHEEL) and let the vehicle idle for 5 minutes. If possible
apply a 20 in-Hg vacuum to the reservoir, while engine is idling.
5. Turn engine off and recheck fluid level, to FULL COLD.
6.If the Steering gear is replacedensure reservoir is at FULL HOT level, start engine and turn wheel to left. Stop
Engine and recheck fluid level to FULL HOT. Start engine and turn wheel to the right. Stop engine and check
fluid level is at FULL COLD.
7. Fill the pump fluid reservoir to the proper level and let the fluid settlefor at least two (2) minutes.
8. Start the engine. With the engine idling maintain the fluid level.
9. Raise the front wheels off the ground.
10. Slowly turn the steering wheel lock-to-lock 20 times with the engine off while checking the fluid level.
NOTE: For vehicles with long return lines or oil coolers turn wheel 40 times.
11. Lower the front wheels and let the engine idle for two minutes.
12. Turn the steering wheel in both direction and verify power assist and quiet operation of the pump.
If the fluid is extremely foamy or milky looking, allow the vehicle to standa few minutes and repeat the procedure.
CAUTION: Do not run a vehicle with foamy fluid for an extended period. This may cause pump damage.
REMOVAL
GAS ENGINE
1. Drain and siphon the power steering fluid from the
reservoir.
2. Remove the serpentine belt.
CAUTION: Do not remove the fitting on the pump
that the high pressure hose screws into. The fit-
ting may come loose unless it is backed up using
another wrench. If the fitting does come loose, it
must be retightened before continuing. (57 - 67
Nm, 40 - 50 lb.ft.). If this fitting comes out of the
pump body, the internal spring and valve parts will
fall out of the pump and they cannot be reinstalled
properly. If this occurs the pump needs to be
replaced with a new pump.
3. Disconnect the return hose (3).
4. Disconnect the pressure hose (4).
5. Access to remove the three bolts securing the pump to the cylinder head can be gained thru the pulley holes (1).

STANDARD PROCEDURE
INITIAL OPERATION
WARNING: The fluid level should be checked with engine off to prevent injury from moving components.
NOTE: Remove as much of the old fluid out of the system as possible with a suction tool or by removing
a hose, when a component has failed. Then refill it with fresh fluid until itis clean. This may have to be
done more than once.
CAUTION: MOPAR
ATF+4 is to be used in the power steering system. No other power steering or auto-
matic transmission fluid is to be used in the system. Damage may result to the power steering pump and
system if any other fluid is used, and do not overfill.
Wipe filler cap clean, then check the fluid level. The dipstick should indicateCOLDwhen the fluid is at normal
ambient temperature.
1. Fill the pump fluid reservoir to the proper level and let the fluid settlefor at least two minutes.
2. Start the engine and let run for a few seconds then turn engine off.
3. Add fluid if necessary. Repeat the above procedure until the fluid levelremains constant after running the engine.
4. Raise the front wheels off the ground.
5. Slowly turn the steering wheel right and left, lightly contacting the wheel stops at least 20 times.
6. Check the fluid level add if necessary.
7. Lower the vehicle, start the engine, and use the DRB III to activate the hydraulic fan on full fan operation.
8. Turn the steering wheel slowly from lock to lock.
9. Stop the engine, check the fluid level and refill as required and repeat the process
CAUTION: Do not run a vehicle with foamy fluid for an extended period. This may cause pump damage.
10. If the fluid is extremely foamy or milky looking, allow the vehicle to stand a few minutes and repeat the pro-
cedure.
11. While the vehicle is in park, use the DRB III to activate the hydraulic fan to full fan operation and briefly rev the
engine up to 3000 rpm to fully engage the hydraulic fan.
12. Check the fluid level add if necessary.
RETURN HOSE - COOLER TO PUMP
NOTE: Review all Warnings and Cautions. (Refer
to 19 - STEERING - WARNING).
CAUTION: Cap all open ends of power steering
hoses, power steering pump fittings and steering
gear ports when disconnected. This will prevent
the entry of foreign material into the components
during servicing.
