Loss of level while running(power steering)and foamy
I replaced the steering gearbox and the power steering pump and filled it up and now when running the fluid level goes down and it foams up.
on the bottom of the pump it has 2 lines but only one has vacuum would that have anything to do with it

Re: loss of level while running(power steering)and foamy
ThTere is aur in the system. Lit sit overnight and then chk. There is no vacuum, it is a return line. I should leak if it can **** air. Remember you replaced the whole system and all the air has to be purged. Chk in yhe morning, giving the air a chance to seperate. Good luck.. Make sure pump does not run low again or it wil take air again.. Do not rev engine while purging further, it just agitatws rge oil ans air.

If the pump went dry there is a chance that it was damaged....replace the line, re-fill with the proper power steering fluid to the full mark, cap it, start the car and turn the wheel all the way right, then left a few times to help fill the rack with fluid. check the level and top it off as necessary. drive the car a few miles and re-check the level. Whining after the reservoir is full indicates damage to the pump, steering rack or both.
spray down pump and hoses with degreaser and wash off. After its dry, use recomended fluid to fill. Start engine and turn steering wheel all the way left, and all the way right a couple of times. This will blead the air from the system. Now shut off and check fluid. Make sure it is full. Now drive the car down the road and make turns, and drive it back and check fluid level. If its still foamy and not leaking fluid, your pump ma be bad.
set the front wheels in straight ahead position by driving vechicle a short distance on a flat surface. raise and support the vechicle safely on jack stands.place a drain pan below the steering gear. disconnect negative battery cable.disconnect fluid lines.cap the openings.mark the relationship of the pitman arm to the pitman shaft.remove pitman shaft nut and then remove the pitman arm from the pitman shaft using puller J - 6632. remove the steering gear to frame bolts and remove the gear assembly. TO INSTALL align the flat of the flexible coupling with the flat on the shaft push the coupling onto the shaft until the wormshaft bottoms against the end of the shaft.install the pinch bolt. make sure the bolt passes through the shaft undercut. tighten the pinch bolt to 75 ft lbs. place the steering gear into position guiding the coupling bolts into the proper holes in the shaft flange. install the steering gear to frame bolts and torque to 66 ft lbs.install the coupling flange nuts and washers. make sure the coupling alignment pins are centered in the flange slots. tighten the nuts to 20 ft lbs. maintain a coupling to flang dimension of 0.250 - 0.375 inches. install the pitman arm.install the hoses. you are done except bleeding power steering system. BLEEDING POWER STEERING. fill the the power steering pump reservoir to the proper level and let the fluid remain undisturbed for at least 2 minutes. start the engine and run it for only about 2 seconds.add fluid as necessary. keep doing this procedure until fluid level stop dropping. then raise the front of vechicle so the front wheels are off the ground.set the parking brake and block both rear wheels front and rear. manual transmission should be in neutral. automatic transmission should be in park. start the engine and run it at approximately 1500 rpm. turn the wheels off the ground to the right and left lightly, contacting the stops.add fluid as necessary. lower the vechicle and turn the wheels right and left on the ground.check the level and refill as necessary. if the fluid is extremely foamy, let the vechicle stand for a few minutes.with the engine off and repeat the procedure. if fluid looks foamy. once all done.dont drive vechicle on highway until normal steering is obtain.
It'll get foamy when there's air in the system, as you're likely to have with a leak or a low fluid level.
Let it settle back down to fluid, check the level, and top it off. If you're lucky, that'll get you running actual liquid again through the pump which should stop the whine for a while. If not, start by lookinf or and fixing any leak and move on from there. The steering gear doesn't like running on foam, and those puppies ain't cheap.
Your problem could be a pressure side hose that has a rupture that only leaks in extreme conditions. Inspect to replace with new to repair problem. First make sure you have removed the pump caps off of the hose fittings. If ok, it appears you may have a stuck valve in the rack assembly. Replacing the rack should solve your problem.-------The new pump should be self-bleeding by turning the wheels left and right. Let sit over night to release air bubbles, recheck fluid level.------Check the tension of the drive belts on the pump, as they may be loose.The power steering pump and reservoir is located on the front of the engine driven by one of the fan belts. There is a removable cap on the top with a dipstick attached. With the engine off, fill this up to the full mark with power steering fluid. Replace the cap, start the engine and check for leaks. On the back of the pump are two hoses either one could be leaking.REPAIR PROCEDURE: 1. Wipe the power steering cap and area free of dirt. Remove the power steering cap.
2. Use a siphon pump to remove as much fluid as possible from the power steering fluid reservoir.
3. With a helper in the vehicle, raise the vehicle on an appropriate hoist.
WARNING :POWER STEERING FLUID, ENGINE PARTS, AND THE EXHAUST SYSTEM MAY BE EXTREMELY HOT IF THE ENGINE HAS BEEN RUNNING. DO NOT START ENGINE WITH ANY LOOSE OR DISCONNECTED HOSES. DO NOT ALLOW HOSES OR POWER STEERING FLUID TO TOUCH HOT EXHAUST MANI FOLD OR CATALYST.4. Locate the power steering cooler attached to the crossmember support plate. Slide back the clamp and disconnect one of the two power steering return hoses at the power steering oil cooler and drain fluid in an appropriate container. 5. Have the helper turn the steering wheel back and forth quickly several times to force as much fluid as possible from the steering gear. 6. Reconnect the hose at the oil cooler using the original clamp. 7. Lower vehicle so the vehicle tires are not contacting the ground.9. For proper fluid fill and bleeding air from the power steering system:
a. Fill the power steering reservoir to the top of the fill range using Mopar power steering fluid (ATF+4) p/n 05013458AA.
b. With the engine OFF and the vehicles tires off the ground, slowly turn the steering wheel back and forth (lock to lock) slowly 20 times to force fluid into the steering gear.
c. Fill the power steering reservoir to the top of the fill range.
d. Start engine and let run for a few seconds, then turn oft engine.
e. Check fluid level and add if necessary.
f. Start engine, and slowly turn the steering wheel lightly contacting the left and right stops.
g. Stop the engine and check fluid level. Add fluid if necessary.
h. Lower vehicle, start engine and slowly turn steering wheel lock-to-lock.
I. Stop engine and check fluid level. Add fluid if necessary.
j. If fluid is extremely foamy, allow vehicle to stabilize a few minutes, then repeat steps "i" and "j" until the fluid level remains constant after running the engine and turning the steering wheel from lock to lock.
10. Inform the vehicle owner/operator that a steering vibration may be noted for a few hundred miles until the air is completely removed from the steering system.This will help. Thanks please keep updated.please do rate the
solution positively .thank you for using fixya
Problems associated with low power steering fluid… Hard Vehicle Steering A low power steering fluid level can often times cause a vehicle's steering to become hard and labored. Adequate amounts of power steering fluid are necessary to enable a vehicle's power steering system to function and operate at optimum levels. A lack of power steering fluid in a vehicle's power steering system reduces the amount of hydraulic fluid pressure necessary to efficiently operating the various parts of the entire power steering system. Power steering fluid supplies the fluid force needed to operate the power steering gears and to enable power steering gearbox operation. Low power steering fluid levels reduce this hydraulic pressure, which commonly results in hard vehicle steering. Pump Noise It is very common for a low power steering fluid level to cause significant power steering pump noise. An adequate amount of power steering fluid is required to ensure the proper function and longevity of a power steering pump unit, which is a belt-driven pump responsible for housing and circulating power steering pump fluid. A low level of power steering fluid results in increased power steering pump friction, heat, and wear, all of which can significantly reduce the operational life of the power steering pump while at the same time cause excessive power steering pump noise. Fluid Boiling
Many times a low power steering fluid level can result in excessive heating of power steering fluid, a condition that can seriously degrade the fluid and cause it to boil. A low power steering fluid level results in less available fluid to both lubricate and cool a power steering pump unit. A lack of power steering pump lubrication and cooling leads to excessive heat being generated within the power steering pump unit itself, a condition that translates into the available level of power steering fluid becoming super-heated and degraded. When this happens it is common for the power steering fluid to boil and lose all of its lubricating and heat-reducing capabilities.
The power steering gearbox is a set of gears within a vehicle's power steering system designed to facilitate movement of a vehicle's front wheels. The power steering gearbox is connected to the power steering pump by hydraulic fluid lines that deliver a constant supply of power steering fluid to the power steering gearbox. A low power steering fluid level, especially a chronic and severe low power steering fluid level, can lead to increased friction and wear within the power steering gearbox assembly, a condition that can significantly shorten the operational life of the power steering gearbox and negatively affect its operation
if gets low definitely a leak foam is pump mixing fluid with air roar is pump cavitation check lines or pump for leak keep fluid at recommended level air bound unit can cause steering difficulty and or failure if need have trained mech look into problem
FIRST OF ALL YOU HAVE TO REMOVE POWER STEERING FLUID.USING A SUCTION GUN OR LARGE SYRINGE.REMOVE MUCH FLUID AS POSSIBLE.WHEN DONE REMOVING POWER STEERING FLUID.YOU NEED A INLINE WRENCH AND OPEN BOX END WRENCH TO REMOVE THE POWER STEERING HOSE.YOU HAVE TO REMOVE POWER STEERING LINE FROM THE RACK.UNDER THE CAR SAFELY RAISE AND SUPPORT VECHICLE. THEN REMOVE THE TIRE OR WHEEL.THEN REMOVE THE INNER FENDER SPLASH SHIELD.ITS GOING TO BE A TIGHT FIT AND HARD PLACE TO GET YOUR HAND TO REMOVE THE POWER STEERING LINE FROM BOTTOM.WHEN DONE.MAKE SURE NEW POWER STEERING HOSE OR LINE HAS NEW O RINGS.WHEN INSTALLING THE THE NEW STEERING HOSE.WHEN ALL IS DONE BLEED POWER STEERING SYSTEM. FILL UP POWER STEERING PUMP TO CORRECT FLUID LEVEL.THEN LET IT SET FOR 2 MINUTES UNDISTURBED.THEN START THE ENGINE RUN IT FOR 2 TO 3 SECONDS.ONLY CHECK THE RESERVOIR AND ADD MORE FLUID AS NECESSARY.REPEAT THE OPERATION UNTIL THE FLUID LEVEL REMAIN CONSTANT.NOW RAISE FRONT OF THE CAR UNTIL THE WHEELS CLEAR THE GROUND START THE ENGINE AND INCREASE THE SPEED TO ABOUT 1500 RPM.NOW TURN THE STEERING WHEEL GENTLY FROM STOP TO STOP CHECK THE FLUID LEVEL.LOWER THE VECHICLE TO THE GROUND WITH ENGINE STILL RUNNING MOVE THE CAR FORWARD SUFFICIENTY TO OBTAIN FULL RIGHT LOCK FOLLOWED BY FULL LEFT LOCK BUT DONT HOLD THE SREERING WHEEL FIRMLY AGAINST THE STOPS.RECHECK THE FLUID LEVEL IF THE FLUID IN THE RESERVOIR IS EXTREMELY FOAMY ALLOW THE CAR TO STAND FOR A FEW MINUTES.WITH ENGINE OFF.WHEN JOB IS FINISH. WARNING DONT DRIVE CAR ON ROAD IF YOUR FLUID STILL FOAMY OR POWER STEERING PUMP MAKE NOISES.REBLEED THE SYSTEM AND CHECK FLUID LEVEL AND CHECK FOR LEAKS.DONT DRIVE CAR UNTIL YOU START FEELING NORMAL STEERING.IF YOU HAVE TROUBLE DONT DRIVE.HAVE IT TOWED TO THE NEAREST GARAGE.
sounds like you may not have all of the air out of the system. one way you can bleed the system is to fill the resivoir start your vehicle and turn the wheel all the way to the right count to ten then the same to the left. shut off your vehicle and check fluid level. if it look realy foamy let it sit a wile. repeat and your problem should be solved.
