Hi my name is ***** ***** I will be happy to assist with this today.In some cases I may need more info to assist better.I apologize for any delay.

Most likely there is still air trapped in the power steering system causing this issue here.Below is the proper power steering bleed procedure that needs followed to remove all air.I would do this one more time properly and see if this corrects the fault.If it continues try it again as sometimes purging all air can be difficult.If the procedure is not done correctly this issue occurs as well.

CAUTION: The fluid level should be checked with engine off to prevent injury from moving components. Use only Mopar(R) Power Steering Fluid. Do not use automatic transmission fluid. Do not overfill.

Wipe filler cap clean, then check the fluid level. The dipstick should indicate FULL COLD when the fluid is at normal temperature of approximately 21°C to 27°C (70°F to 80°F).
1. Fill the pump fluid reservoir to the proper level and let the fluid settle for at least two 2 minutes.
2. Start the engine and let run for a few seconds. Then turn the engine off.
3. Add fluid if necessary. Repeat the above procedure until the fluid level remains constant after running the engine.
4. Raise the front wheels off the ground.
5. Start the engine. Slowly turn the steering wheel right and left, lightly contacting the wheel stops.
6. Add power steering fluid if necessary.
7. Lower the vehicle and turn the steering wheel slowly from lock to lock.
8. Stop the engine. Check the fluid level and refill as required.
9. If the fluid is extremely foamy, allow the vehicle to stand a few minutes and repeat the above procedure.

I apologize for the delay as I was offline when you replied last night.

Was this a noise issue before the pump was changed as well?

Customer: replied 9 months ago.
No the noise wasn't there till after the pump was changed but the noise sounds as if there was no power steering fluid in the reservoir
Expert:  Pete replied 9 months ago.

O.k.,since the noise was not an issue until after this was replaced and you have followed the power steering bleed procedure here it sounds like you have obtained a faulty power steering pump.I have seen some of these faulty new out of the package and had to parts warranty it (obtain another new one from the facility you purchased it from at no cost to you) and replace it again,then follow the correct bleed procedure above to correct this issue.

If the procedure was followed,you have no air bubbles and fluid is full the pump is faulty needing replaced again unfortunately.I would contact the facility you got it from and let them know and they should be able to provide one at no cost to you.

Let me know if you need anything else and feel free to rate my help here as this is how I receive credit for my time.Your 5 star rating is appreciated

Thanks Pete
