How do I replace the power steering fluid hose?
I've got a slow leak in my power steering near the rack and pinion. Is this something I can fix myself, and if so, how do I go about doing so?
Is this a good question?

This is from a service bulletin. Sorry that there are no pictures, even though it references Figure 3 for the correct way to wrap the hose in place. I would say to pay close attention to where it is now, maybe even take a picture for yourself.
REPLACE POWER STEERING HOSE:
1. Cut 850 mm (33.5 in.) of power steering hose (p/n 05135964AA) or equivalent.
2. Cut 790 mm (31 in.) of 15.9mm (5/8 in.) or 17.5 mm (11/16 in.) convolute tubing. Place the convolute tubing around the power steering hose.
3. Open hood and remove the power steering reservoir cap.
4. Raise the vehicle on an appropriate hoist.
5. Locate the power steering cooler attached to the crossmember support. Remove the forward (closest to front of vehicle) hose from the cooler and tube. Drain the power steering fluid in an appropriate container.
6. Remove the two tension clamps from the removed hose and install on the new power steering return hose.
7. Install the new hose and tension clamp onto the power steering cooler.
8. Wrap the hose clockwise around the perimeter and on top of the power steering cooler as shown in (Fig. 3). Install the hose and tension clamp to the power steering return tube.

1 - COOLER RETURN TUBE (CLOSEST TO FRONT OF VEHICLE)
4 - TIE STRAP LOCATIONS
2 - RETURN TUBE TO RESERVOIR 5 - POWER STEERING COOLER
3 - CROSSMEMBER SUPPORT 6 - POWER STEERING COOLER HOSE (ROUTE CLOCKWISE)
9. Use two tie straps to strap the return hose to the power steering cooler and pressure steering hose shown in (Fig. 3).
10. Lower vehicle and open hood.
11. Proceed to “Steering/Pump - Standard Procedure”.

STEERING/PUMP - STANDARD PROCEDURE
WARNING:FLUID LEVEL SHOULD BE CHECKED AND ADJUSTED WITH ENGINE OFF TO PREVENT INJURY FROM MOVING ENGINE COMPONENTS.
CAUTION: Use only Mopar® ATF+4 Automatic Transmission Fluid (MS-9602) in power steering system. Use of other Mopar® power steering fluids (MS5931 and MS9933) should be avoided to ensure peak performance of the power steering system under all operating conditions. Do not overfill. Read the fluid level through the side of the power steering fluid reservoir. The fluid level should be within “FILL RANGE” when the fluid is at a temperature of approximately 21°C to 27°C (70°F to 80°F).
1. Wipe the filler cap and area clean, then remove the cap.
2. Fill the fluid reservoir to the proper level and let the fluid settle for at least two (2) minutes.
3. Start the engine and let run for a few seconds, then turn the engine off.
4. Add fluid if necessary. Repeat the above steps until the fluid level remains constant after running the engine.
5. Raise the front wheels off the ground.
6. Start the engine.
7. Slowly turn the steering wheel right and left, lightly contacting the wheel stops.
8. Add fluid if necessary.
9. Lower the vehicle, then turn the steering wheel slowly from lock-to-lock.
10. Stop the engine. Check the fluid level and refill as required.
11. If the fluid is extremely foamy, allow the vehicle to stabilize a few minutes, then repeat the above procedure.

Do not use any PS fluid with a stop leak. This can sometimes clog your PS pump. Just have the hose replaced. It can be easy or hard depending on the type of vehicle. Another thing, this goes for the radiator. Adding stop leak into your radiator can clog your water pump.

You need to make sure that you get the correct hydraulic hose and fittings otherwise a lot of problems can come from trying. GL my good man, GL.

if it's the pressure hose, make sure you have a lift, you have about 2" to loosen up one of the fittings, and make sure you have an 18 mm shorty wrench, it's not fun, but I did it in about an hour but my neighbor let me use his lift, I would say about 3 hours on the ground and many many swear words

Use pb blaster and let it sit to soak into the threads and if that dont work since ur replacing the hose use heat until the nut turns glowing orange and den quickly use a flare wrench with the appropriate size and break it loose
The more pb blaster the better and heat like a peopane torch bottle or something let me know how it goes

Have you tried filling it up with one of those combination power steering fluid and leak sealers to see if that helps?
