New ps pump that whines under acceleration
Hey guys hopefully someone can help me out, I just got done replacing my whole steering system, new box, hoses and a pump. Steering has tightened up immensely but my pump under acceleration sounds like a little supercharger under the hood. Is this because it’s a new remanufactured unit? It doesn’t make noise at idol or when turning the wheel at a standstill. I did the proper bleeding process and the fluid doesn’t look foamy.

It sounds like you still have air in the lines at this point.
What kind of power steering fluid did you use?
Did you flush the system?
I just did the Durango gear, and new pump. It took a whole lot of work to bleed the whole system.
If you have a Mighty-vac I would suggest using that to help bleed the air out. The Cherokee power steering system is a bear to get all the air out of the lines.
Did you have anyone help you on the bleeding?
It totally helps to have someone turning the steering wheel lock to lock, whilst you keep adding fluid, and checking for air bubbles while your Jeep is up on the jack stands.

You ALWAYS have to flush the system, even when new.
The re manufacture/ manufacturer uses crappy transmission fluid usually when pressure testing the components.
Also there will be small metal particles in the fluid after the rebuild.
So basicly it will take you around three quarts of PSF to flush, and bleed the system properly.
Don't use ATF for power steering fluid.
Spend a few bucks and buy good fluid, it will save you grief in the long run.
