I have a '93 Ranger, 2.3L w/ the M50D Transmission. The Power Steering Pump is leaking badly and I guess needs to be replaced. I know you need a special tool to get the pulley off. Other than that trick is there anything particularly difficult about this job? I was reading the Haynes Manual on it last night and it seemed kind of generic. Haynes has you taking both front wheels off to do this job. Not sure why. Any help and direction you all can give me will be most appreciated. Thanks.

Power Steering Pump and Pulley

Removal

1. Disconnect the power steering return hose at pump connection and drain fluid.

2. Remove the pressure hose from the pump.

3. On the 2.3L I-4 and 4.0L V-6 engines, slacken belt tension by lifting tensioner pulley in a counterclockwise direction. On Ranger 3.0L V-6 engines, slacken belt tension by lifting tensioner pulley in a clockwise direction. Remove drive belt from under tensioner pulley and slowly lower pulley to stop. Remove the drive belt from the power steering pump pulley.

4. Remove the drive belt from the power steering pump pulley.

5. Remove the oil dipstick tube, if necessary.

6. Remove the power steering pump bracket support brace, if equipped.

7. Install Steering Pump Pulley Removal Tool T69L-10300-B or equivalent on the pulley.

8. While holding the remover tool nut stationary with a wrench, rotate the inner spindle of the remover tool clockwise until the pulley is pulled off the power steering shaft.

NOTE:
Do not apply pressure on the pump shaft. Pressure will damage internal thrust areas of the pump.

9. Remove the bolts attaching the pump to the bracket and remove the pump.


Installation

1. Install the pump on the bracket. Install and tighten attaching bolts to 41-61 N-m (30-45 ft-lbs). On 4.0L engine, tighten to 47-64 N-m (35-47 ft-lb).

2. Position the support on the bracket. Install mounting bolts and tighten to 47-64 N-m (35-47 ft-lb).

3. Install the Steering Pump Pulley Replacement Tool T65P-3A733-C and install the pulley. Remove the tool.

NOTE:
Fore/aft location of pulley on power steering pump shaft is critical. Incorrect belt alignment may cause belt squeal or chirp. Make sure pull-off groove on pulley is facing front and flush with end of shaft ± 0.254mm (± 0.010 inch).

4. Install the belt on the pulley.

5. On the 2.3L I-4, Ranger 3.0L V-6, and 4.0L V-6 engines, position and rotate drive belt on engine. While lifting tensioner pulley in a counterclockwise direction (clockwise on Ranger 3.0L V-6), slide belt under tensioner pulley and lower pulley to belt.

6. Install the power steering pump bracket support brace, if removed.

7. Install the oil dipstick tube, if removed.

8. Install the pressure hose tube nut into pump outlet fitting and tighten to 41-54 N-m (30-40 ft-lb).

9. Connect the return hose to the pump, and reposition the clamp.

10. Fill the reservoir with Premium Power Steering Fluid E6AZ-19582-AA (ESW-M2C33-F) or equivalent. Start the engine and turn the steering wheel from left to right without hitting stops to remove air from the system.

11. Check for leaks and recheck the fluid level.

 

Make sure that is the front seal that is leaking. Usually it is one of the hoses. The high pressure hose developes a pinhole and gets oil everywhere. So be sure before tearing it apart and possibly save yourself some headaches.jd

 

Thanks for the suggestions and direction. I will let you know what I find.

 

O.K. so it turned out to be the high pressure hose on the PS Pump. The motor mounts had sagged enough to let the hose make contact with the frame and rub a hole. We replaced the left side mount and the hose and are good to go now. Thanks.
