Have a Isuzu Trooper 94 double camshaft 3.2 doc the steering wheel is very heavy to turn toward the sides. I Change the pump power and given service, but continuous heavy turning the steering wheel

Your steering is power assisted. The pump is driven via a toothed wheel from the engine.
I would suspect something is obviously awry with the pump or there is no/low fluid in the system.

SERVICE PROCEDURE: THE POWER STEERING FLUID REPLACEMENT PROCEDURE IS A TWO-STAGE PROCESS: FIRST, FLUSHING THE OLD FLUID FROM THE SYSTEM WITH NEW FLUID; AND SECOND, BLEEDING THE SYSTEM TO REMOVE ANY TRAPPED AIR. THE FOLLOWING TWO SEQUENCES OUTLINE THE STEPS IN EACH PROCEDURE.

FLUSHING THE POWER STEERING SYSTEM 1. RAISE THE FRONT END OF THE VEHICLE OFF THE GROUND UNTIL THE WHEELS ARE FREE TO TURN.

2. REMOVE THE FLUID RETURN LINE AT THE PUMP RESERVOIR INLET CONNECTOR.

3. PLUG THE INLET CONNECTOR PORT ON THE PUMP RESERVOIR.

4. POSITION THE FLUID RETURN LINE TOWARD A LARGE CONTAINER IN ORDER TO CATCH THE DRAINING FLUID.

5. WHILE A SECOND PERSON FILLS THE RESERVOIR WITH NEW LOW TEMPERATURE CLIMATE SERVICE FLUID, START AND RUN THE ENGINE AT IDLE.

6. TURN THE STEERING WHEEL FROM STOP TO STOP.

NOTICE: DO NOT HOLD THE WHEEL AGAINST STOPS WHILE FLUSHING THE SYSTEM. HOLDING STEERING WHEEL AGAINST WHEEL STOPS WILL CAUSE HIGH SYSTEM PRESSURE, OVERHEATING, AND DAMAGE TO THE PUMP AND/OR GEAR. 7. CONTINUE DRAINING UNTIL ALL OF THE OLD FLUID IS CLEARED FROM THE POWER STEERING SYSTEM. ADDITION OF APPROXIMATELY 1 QUART OF NEW FLUID WILL BE REQUIRED TO FLUSH SYSTEM.

8. UNPLUG PUMP RESERVOIR INLET AND RECONNECT RETURN LINE.

9. TURN ENGINE OFF, AND FILL RESERVOIR TO THE "FULL COLD" MARK.

10. CONTINUE WITH FOLLOWING PROCEDURE "BLEEDING THE POWER STEERING SYSTEM".

BLEEDING THE POWER STEERING SYSTEM AFTER REPLACING THE FLUID OR SERVICING THE POWER STEERING HYDRAULIC SYSTEM, YOU MUST BLEED AIR FROM THE SYSTEM. AIR IN THE SYSTEM PREVENTS AN ACCURATE FLUID LEVEL READING, CAUSES PUMP CAVITATION NOISE AND OVER TIME COULD DAMAGE THE PUMP. TO BLEED THE POWER STEERING SYSTEM PROCEED AS FOLLOWS:

1. BEGIN WITH THE ENGINE OFF, FRONT WHEELS OFF THE GROUND, AND WHEELS TURNED ALL THE WAY TO THE LEFT.

2. ADD LOW TEMPERATURE CLIMATE SERVICE FLUID TO THE "FULL COLD" MARK ON THE FLUID LEVEL INDICATOR.

3. BLEED THE SYSTEM BY TURNING THE WHEELS FROM SIDE TO SIDE WITHOUT HITTING STOPS.

IMPORTANT: THIS MAY REQUIRE TURNING THE WHEELS FROM SIDE TO SIDE TWENTY TIMES. ON SYSTEMS WITH LONG RETURN LINES OR FLUID COOLERS, TURNING STEERING WHEEL LOCK-TO-LOCK FORTY TIMES MAY BE REQUIRED. KEEP THE FLUID LEVEL AT THE "FULL COLD" MARK. FLUID WITH AIR IN IT HAS A LIGHT TAN APPEARANCE. THIS AIR MUST BE ELIMINATED FROM THE FLUID BEFORE NORMAL STEERING ACTION CAN BE OBTAINED. 4. START THE ENGINE. WITH THE ENGINE IDLING, RECHECK THE FLUID LEVEL. IF NECESSARY, ADD FLUID TO BRING THE LEVEL TO THE "FULL COLD" MARK.

5. RETURN THE WHEELS TO THE CENTER POSITION. LOWER FRONT WHEELS TO THE GROUND. CONTINUE RUNNING THE ENGINE FOR TWO OR THREE MINUTES.

6. TEST THE VEHICLE TO BE SURE THE STEERING FUNCTIONS NORMALLY AND IS FREE FROM NOISE.

IMPORTANT: INSPECT FOR FLUID LEAKAGE AT CONNECTION POINTS ALONG THE POWER STEERING SYSTEM. 7. RECHECK THE FLUID LEVEL AS DESCRIBED IN STEPS 3 AND 4 EXCEPT THAT THE FLUID LEVEL SHOULD NOW BE UP TO THE "FULL HOT" MARK AFTER THE SYSTEM HAS STABILIZED AT ITS NORMAL OPERATING TEMPERATURE.

double posted now double answered, do we get 3 time?
its the only 16pin empty female on car.... D-shell shaped in USA.

Here is a diagram, I just want to make sure we have the correct information or engine damage will occur. double check these specs. 1999 ISUZU TROOPER V-6 WITH A 3.2 OR 3.5 ENGINE.

Here are two diagrams to line up camshafts and crankshaft. hope this is helpful. good day.

I had this happen on my 94 automatic. 4x4 "engages" but no power to front wheels. One of the front axles went bad so the 4x4 doesn't engage on either front wheel. It was a $800 fix.

you need the ignition key to unlock it, if it doesn't work with the key you may need a new key.

Firstly, if your steering wheel will rotate about an inch, while in the locked position, do the following:

1) swing the wheel as far as it goes, then hold it tightly in position (it may want to return back to position, butdon't let it go!)

2) insert key into ignition, and turn key to "ON", not start.

3) see if steering wheel will now release...


Please advise if this works...

If no, then need to go to next step...

Await your response....

check the power steering pump, if its good than it will be rack and pinion issue. the pump create a high pressure to help assist with steering, and the rack and pinion work like hydraulic cylinder which receive the pressure from the pump and the steering work like control valves. by turn left or right you controling the pressure to make the wheels turn either right or left. check and see if you have any leaks.

turn steering wheel full right then full left should go away after a while

youre leaking steering box is most likely an easy fix, the leak can be rectified by changing the lower shaft seal but this means removal of the pitman arm. you can remove the seal and get it matched up at any industrial supplier
