Will atf puty in steering pump and geer box make power steering box more noise than using power steering fluid in the jeep cherokee

MS5931 IS THE ONLY FLUID THAT CAN BE USED FOR THE POWER STEERING SYSTEM. NO EXCEPTIONS!

Important note: The factory fill power steering fluid for all 1999-2004 Grand Cherokees is a unique fluid, MS5931. ATF+4 (MS9602) should not be mixed or used as a “topping off” fluid on the Grand Cherokee WJ. All WJ models should be serviced using ONLY the special MS5931 fluid. ATF+4 is NOT an approved Power Steering Fluid and should never be used under any circumstances. Note that all fluids will darken in color with usage and fluid color is no longer an indication of fluid condition.
The 'foaming' you describe is almost certainly air getting into the system. The power steering pump will cause a suction effect in the pump and then pressurize the system. Look for loose hose clips, damaged piping, and leaking seals on the pump body between the pump and its fluid reservoir

The hydraulic fan runs off of pressure from the power steering unit. I would recommend that you check the fluid level on your power steering pump. It is more common for the power steering pump to give issues than for the fan to go out. That being said, if you can notice any whining noise, lag, or lack of assist when turning the steering wheel, it is either the fluid level, or the power steering pump.

I hope that you have found this information to be useful, and if I can be of any further assistance, please let me know. Thank you for using fixya!

Yes, it could lead to abnormal wear, and early failure. Check your power steering fluid.

Use power steering fluid available in auto parts stores. If you can't find power steering fluid, use Automatic Transmission Fluid (ATF) -- they're essentially the same.

It would be best to follow what your user's manual specifies, but I assume you don't have that.

P.S. Some manufacturers even specify ATF for the power steering pump.

For the Power Steering Pump, refer to the 1995 ZJ Service Manual (Section-19-Steering / page 9 and next)

Hope helped with this (remember rated this help) Good luck.

dextron II or III

If its a whining noise, check the power steering fluid level and fill if low, otherwise you may have a pump going out or a loose belt

Use Dexron® II or ATF Plus/Type 7176 automatic transmission fluid (or their superceding fluid type).

use what the manual suggest to use. it should be standard power steering fluid. do not use ATF. ATF is automatic transission fluid.
you only use this if the manual says to usually only on a merzades.
the wining noise could be the pump breaking it's self in. it will do this for a while untilt he pump is completley broke in and is used to the being used.

If it only goes stiff part of the time, the box is probably OK.

Before considering major surgery:

• check the power steering fluid level.
• condition of the fluid
• condition and tension on the belts
• check for low or uneven tire pressure
• check steering linkages for damage (did someone borrow the car recently?)

If none of these check out, then consider replacing the pump.
