My power steering is not working, i changed the pump, and pulley, also changed the fluid and bleed it in. what else could it be? Also, when steering the wheel inside the cab, i hear a little ticking coming from the steering colunm, could it be an electrical issue?

first you need to remove power steering pump drive belt and fluid using a large syringe or siphon pump.then you need place drain pan under vechicle where power steering pump located,remove power steering return line and remove power steering pressure hose using a flare nut wrench,make sure drain pan catch power steering fluid. once you have the power steering pump return hose and pressure hose remove,then remove power steering pump mounting bolts then remove power steering pump.take old power steering pump and new power steering pump to machine shop or garage so they can transfer drive pulley from old power steering pump to the new pump,once you have new power steering pump ready to install be sure to buy new pressure hose o ring if equipped, you need to bleed power steering system once you have new pump in place with every thing back in place cant give you bleeding procedure you did not tell me vechicle type you working on.

YOU FIRST YOU NEED TO REMOVE COOLANT RECOVERY RESERVOIR. YOU NEED TO REMOVE DRIVE BELT.NOW PLACE DRAIN PAN UNDER CAR IN LINE WITH POWER STEERING PUMP.NOW SIPHON OUT MUCH POWER STEERING FLUID OUT RESERVOIR USING A SIPHON.ONCE FLUID REMOVE OUT POWER STEERING PUMP.USE A DEEP 3/8 SOCKET ABOUT 13M OR 14 M YOU NEED A SHORT EXTENSION AND A 3/8 RATCHET WRENCH.TO REMOVE POWER STEERING PUMP.TO LOOSEN BOLTS, TAKE DEEP SOCKET IN PULLEY HOLES . LOOK THROUGH POWER STEERING PULLEY HOLES ALIGN DEEP SOCKET THROUGH THE PULLEY HOLES TO THE PUMP BOLTS. LOOSEN ALL THREE BOLTS. YOU HAVE TO TURN PULLEY THREE TIMES TO REMOVE ALL THE POWER STEERING PUMP BOLTS.ONCE POWER STEERING PUMP BOLTS REMOVED.TAKE OLD POWER STEERING PUMP TO THE MACHINE SHOP.THEY WILL HAVE TO REMOVE PULLEY OFF OLD PUMP AND TRANSFER DRIVE PULLEY TO NEW POWER STEERING PUMP.NOW WHEN YOU INSTALL NEW POWER STEERING PUMP.MAKE SURE TO BUY A NEW O RING FOR THE HIGH PRESSURE HOSE TO POWER STEERING PUMP. WHEN ALL DONE BLEED POWER STEERING PUMP. WITH THE FRONT WHEELS TURNED ALL THE WAY TO THE LEFT AND THE IGNITION KEY OFF, CHECK THE POWER STEERING FLUID LEVEL AND IF LOW ADD FLUID UNTIL IT REACHES THE COLD MARK ON THE DIP STICK.SAFELY RAISE FRONT WHEEL OFF GROUND BY SUPPORTING FRONT OF THE CAR USING JACK STANDS, MAKE SURE CAR SITTING ON SOLID LEVEL GROUND. START THE ENGINE AND ALLOW IT TO RUN AT FAST IDLE.RECHECK THE FLUID LEVEL AND ADD MORE IF NECESSARY TO REACH THE COLD MARK ON THE DIP STICK.BLEED THE SYSTEM BY TURNING THE WHEELS FROM SIDE TO SIDE WITHOUT HITTING A STOPS.THIS WILL WORK THE AIR OUT OF THE SYSTEM. DONT ALLOW THE RESERVOIR TO RUN OUT OF FLUID. WHEN AIR IS WORKED OUT OF THE SYSTEM.RETURN THE WHEELS TO THE STRAIGHT AHEAD POSITION, AND LEAVE THE ENGINE RUNNING FOR SEVERAL MINUTES BEFORE SHUTTING OFF. RECHECK THE FLUID LEVEL.ROAD TEST THE VECHICLE TO BE SURE THE STEERING SYSTEM IS FUNCTIONING NORMALLY WITH NO NOISE.RECHECK THE FLUID LEVEL TO BE SURE ITS UP TO THE HOT MARK ON THE DIP STICK WHILE THE ENGINE IS AT NORMAL OPERATING TEMPERATURE ADD FLUID IF NECESSARY.

FIRST OF ALL TURN OFF RADIO REMOVE NEGATIVE BATTERY CABLE. THEN REMOVE POWER STEERING PUMP FLUID FROM POWER STEERING PUMP.USING A HAND PUMP SIPHON. BE CAREFUL DONT GET POWER STEERING FLUID ON CAR PAINT IT WILL DAMAGE PAINT JOB.PUT A DRAIN PAN UNDERNEATH CAR TO CATCH POWER STEERING FLUID THEN DISCONNECT POWER STEERING PUMP LINES.REMOVE POWER STEERING PUMP ADJUSTER BOLT AND MOUNTING BOLT.REMOVE POWER STEERING PUMP.MOST OF THE TIME NEW POWER STEERING PUMP DONT HAVE DRIVE PULLEY ON IT SO TAKE TO A MACHINE SHOP THE WILL REMOVE PULLEY FROM OLD PUMP AND PRESS ON THE PULLEY TO NEW POWER STEERING PUMP.BESURE TO BUY NEW O RINGS TO END OF PRESSURE LINE.ONCE NEW POWER STEERING PUMP HAS PULLEY IN PLACE AND YOU HAVE NEW O RING FOR HIGH PRESSURE LINE.INSTALL NEW PUMP.ADJUST BELT TENSION.NOW BLEED POWER STEERING PUMP WITH FRONT WHEELS POINT STRAIGHT A HEAD POSITION.POUR POWER STEERING FLUID IN PUMP UNTIL FLUID LEVEL ON COLD MARK ON POWER STEERING PUMP DIP STICK.KEEP ADDING FLUID UNTIL FLUID STOP DROPPING. START THE ENGINE LET IT RUN AT IDLE ADD MORE FLUID IF DROPS KEEP FLUID ON FULL COLD MARK.ON DIP STICK TURN OFF ENGINE.CHECK TO MAKE SURE POWER STEERING PUMP NOT LEAKING AT THE LINES THEN.SAFELY RAISE SUPPORT FRONT OF THE VECHICLE WITH JACK STANDS. MAKE SURE VECHICLE ON SOLID LEVEL GROUND CHECK.FLUID LEVEL MAKE SURE AT FULL COLD MARK. NOW START ENGINE.LET IDLE MINUTE.THEN TURN STEERING WHEEL ALL THE WAY TO THE LEFT TO RIGHT SEVERAL TIMES WITH OUT STOPPING IT IN PLACE. CHECK POWER STEERING FLUID WHEN FLUID LEVEL STOP DROPPING.AND FLUID IS NOT A TAN COLOR WHICH MEAN LOTS OF AIR IN SYSTEM. TURN OFF CAR UNTIL AIR BUBBLES DISAPPEAR.CHECK FLUID LEVEL BLEED POWER STEERING AGAIN. DONT DRIVE VECHICLE UNTIL STEERING FEEL NORMAL.IF FLUID REMAIN TAN WITH AIR BUBBLES CHECK FOR LEAKS AT POWER STEERING PUMP PRESSURE HOSE ORING. AND CHECK POWER STEERING LINES TO PUMP FOR LEAKS.

1. Installation is the reverse of the removal procedure. Tighten the pump mounting bolts to 18 ft. lbs. (25 Nm).
2. Bleed the power steering system to remove trapped air. Air in the system could cause noise and or damage to the pump.

BLEEDING

This procedure requires the help of an assistant.

1. With the engine OFF, the wheels off the ground and turned all the way to the left, fill the fluid reservoir to the FULL COLD mark on the fluid level indicator.
2. With an assistant checking the fluid level and condition, bleed the system by turning the wheels from side to side without hitting the stops. You should repeat this at least 20 times, making sure to 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.
See Figure 4

Fig. Fig. 4: Power steering bleeding procedure

1. Start the engine, and while it is idling, recheck the fluid level and add as necessary to reach the FULL COLD mark.
2. Return the wheels to the center position. Lower the front wheels to the ground and continue running the engine for 2 or 3 minutes.
3. Road test the vehicle to make sure the steering functions properly and is free of noises.
