Let the modding Begin!!

***NOTE - This was done on a 1999 2.5L Ranger. It may vary some on different motors and vehicles. This is just a general guide as to how to do it. Also, I replaced my pump because the old one was whining. The new pump did NOT fix this. It made it worse.

Tools Needed:

• Assorted Wrenches
• Power Steering Pulley Puller Kit
• Heater (If garage is cold)
• ATF (Automatic Transmission Fluid)
• Channel Lock
• 3/8" Breaker Bar or Ratchet

You need to go out and rent a power steering puller kit if you dont have one. It will look like this:


The first thing you need to do is get the belt off of the pulleys. Put a 3/8" Breaker bar or a 3/8" ratchet in the slot on the idler pulley to releave the tension off the belt. Make note of the routing of the belt.



Take the belt off the Power Steering Pulley. You do not need to remove the whole belt from the truck. You can if you want to though.

The next thing to do is pull the pulley off of the power steering pump while it is still mounted to the motor. You cant get the bolts out to take the pump off anyway without taking the pulley off. This is the setup you will need to get the pulley off:


You will turn the nut counter clockwise on the bolt




Next thing to do is get the high pressure side line off. This is the one that is threaded and has a head on it. For me this took a 18mm open ended wrench to get it off. I suggest putting a rag under it when taking it out since there is some fluid in the pump.




Next I took the three bolts out of the front of the pump to remove the pump from the bracket. I believe this was a 17mm socket but dont hold me to it.


After the pump was free. I removed the clamp that is holding on the return line on the back of the pump. I used a pair of channel locks to get it off.


Once everything is off the pump, pull it out.




Now put your new pump in. Put your return line back on and then put the bolts in. Tighten them up snug. Then put you high pressure side line back on.


You will need this tool setup from the kit to put the pulley back on.




The inside of the pump shaft it threaded. Tighten the bolt into it. You now start tightening the nut on the threaded bolt until the pulley is back on. You can eye ball the pulley to see if it is inline with the other pullies on the motor.






Now that you have your pulley back on, put the belt back on. Make sure it is in the correct order. You can look at the sticker on the truck infront of the motor to tell you how to put it on.

Now fill the reservoir back up with fluid. Mine takes ATF. Consult your owner's manual for the correct fluid.

Yay, your done. Now start your truck up and see if it works.

 

You said your engine was whining but this didn't fix it, it made it worse. Did you ever fix it?

 

The whining/moaning etc is caused by a bad pump, OR air in the line, it seems Ford systems have terrible air lock areas.

Obviously with a new pump, it's not the pump any longer, but i've had a vacuum pump on mine several times, gets a little better each time, then once the steering wheel shudder is down to a minimum or gone, short drives will help get rid of more air.

Top up the fluid when it's cold, vacuum more if you want/need and go for another 5-10 minute drive, top up fluid when cold again - it should be getting quieter.

 

my pump came with a teflon washer and one small neopreme washer but no instruction on where or how.

 

I used that in the high pressure line, i used the one that seemed to sit flat with the end of the hose, but had to carefully walk it into the female side so it wouldn't fall over and foul the passage-way.

 

after replacing mine it turned on truck now my truck shakes like I have a bad idle thinking I didn't align the pulley ?

 

Look at the face of the pulley and see if it is sitting flush with the shaft on the pump. Also look at it while engine is at idle, if it's on crooked, you will see the wobble
