Need to replace power steering pump.

Remove the accessory drive belt from the pump
Remove the pressure hose from the pump
Remove the return hose from the pump

Remove the bolts from the pump.

Remove the power steering pump from the vehicle.

Remove the power steering pump pulley from the pump

Remove the reservoir from the pump

Install the pump to the vehicle.

Notice: Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.

Install the power steering pump bolts.

Tighten
Tighten the power steering pump bolts to 34 N·m (25 lb ft).
Install the return hose to the pump.
Then just reverse what you did to remove.
Once you have it al back together fill the resevoir.
Do not over fill

Start the engine. Rotate steering wheel from left to right. Check for sign of cavitation or fluid aeration (pump noise/whining).

Verify the fluid level. Repeat the bleed procedure if necessary

Below is the proceedure for replacing your power steering pump.
Good luck.





REMOVAL AND INSTALLATION

1. Disconnect the negative battery cable.
2. Disconnect and cap the power steering pump hoses.
3. Remove the accessory drive belt.
4. Remove the power steering pump pulley using a suitable puller tool.
5. Remove the pump mounting bolts and remove the pump from the vehicle.

See Figures 1, 2 and 3

Fig. Fig. 1: On some vehicles, you must use a puller to remove the power steering pump pulley

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.
