You have air in the lines from changing everything out. if the put and rack and pinion are new you have to work the wheel back and forth to get the air out of the lines

    its going to take awhile for it to get broken in so the foaming may be there for awhile but mostly its normal until all the air is out of the lines

Sounds like it hasn't bled all the air out of the system yet. Did those new parts not come with proper instructions for bleeding out the air? I would think it will take a while before it's all out (air) due to replacement of both parts. I'll see what I can find, but normally I would run engine, & turn steering back & forth slowly until it's out but maybe that vehicle has a different procedure. Will see what we can find.

    Same as I thought, Make sure you check fluid level often & run it end to end,slowly, 20-25 times. If it still growls a little, you still have air, check fluid level & keep trying.

    Only thing that comes to mind is fluid lines reversed on pump, or improper fluid.

I installed a power steering pump for a 99 mitsubishi eclipse spyder gs...my question is, i noticed a leak under the car by the drivers side running through a tubing, what could it be?


Rack and pinion is leaking on it. It has 2 small metal tubes on it that transition the fluid from one side to the other when turning that are bad about getting small pin holes in them over time.

Loss of power steering


If fluid level is up and pump drive belt is not slipping it could be an early indication of either a pump issue or seals/valving issue in steering sector/steering rack.

If fluid looks like it has a metallic look to it like some paint finishes do- replacement of both units is in order.

If fluid looks clean, just dark and oxidized, look for loose or leaking hoses. Also check for possible mechanical interference with steering, loose colmn to dashboard, loose or binding flex coupling, or loose power steering rack, inner and outer tie rod bind, even ball joints or king pins that might be close to siezing.

The steering is hard to move and the steering warning light is on. Please let me know what to do I need to urgently resolve it.


The servo unit on the steering has failed . Look inside the engine bay for oil leaks - if none are present then the entire steering rack will have to be replaced - the internal seals have failed.

Where do you put power steering fluid in a 2007 malibu Ltz.


Power Steering Fluid Power steering pumps are ordinarily lubricated with power steering fluid. Use the correct type for the vehicle. Check the owner's manual if you are unsure.

Usually it's a belt driven power steering fluid pump that has hoses that lead to the rack and pinion steering.

Unscrew the cap and add power steering fluid to it there.

a few possibilities.
Low power steering fluid. check for correct amount on pump filler measureing guage.

Loose power steering belt. check to see if the belt slips over the power steering pulley while trying to turn the steering wheel. may need an assistant.

last, but most expensive. Rack and pinion steering bar is defective and needs replacing.

Power steering pump is stiff on occasion not only in the morning but sometimes during the day also.fluid is at normal level. belts have been replaced last year?


The fluid check valve built into the power steering pump may be bypassing your pressurized fluid back to the reservoir, and not assisting your steering input. You may need a new pump. The only way to know for sure is to have the power steering output checked with a guage set.

Orange fluid leak (most likely power steering fluid)


Check your hoses around your power steering resevoir, you might have a pin hole leake in one of the hoses. Make sure to keep an eye on the fluid level. As long as you keep fluid in it you won't burn out the pump.

Power steering fluid leaks quickly out 1989 Volvo 740 GLE wagon


The most obvious places are the Power steering rack itself - at each end, and the hoses that are attatched to it.
A leak at the pump is easily spotted.

Hoses are cheaper to replace than seals on the rack (which may require a new unit)
