Replaced power steering unit on 95 maxima It sill whines?
Check the tension on the belt. A power steering pump will whine if there is too much belt tension, putting pressure on the side of the pulley.
Was this answer useful?
Thanks for the feedback!
Cost for replacing a power steering belt is $50.00. Stop being greedy, That's what got us in this ugly world, with ugly minds. Money is the root of all evil; wh…ich is the main topic of all that surrounds us. SAD VERY SAD.
Just unscrew both sides of the hose you are replacing. Compare it to your new hose, check if the new hose came with the proper O-rings if not reuse the old ones. Once you have… tightened up both ends of the hose if is a good idea to use a floor jack to lift the front of the car just enough to raise the tires off the ground. Take the cap off of the power steering pump. Turn the steering wheel to the left and right until you do not see any more bubbles come up (add more fluid as needed). Once you confirm you dont see anymore bubbles put the cap back on, lower the car and start the vehicle, turn the wheel a few more times, it may or may not be making the squeeling noise this is normal once you drive it around for a day or so the noise should stop. If you are talking about the high pressure power steering hose on the maxima 2002 some of the above will not be helpful. I suggest going to. http://forums.maxima.org/showthread.php?p=7590103#post7590103 or you might find the following helpful, too.

Suggest reading most posts, esp. ones with pictures, esp. latest 2010 ones. Taking off about an hour once you locate hose and bolts (see pictures in forum) and putting on about 1.5. because of difficulty getting banjo lined up and reconnecting center bracket plate and screw.(I used tie wraps- works perfectly). Attached upper bracket loosely then, let hose drop down, attached banjo then center, then tightened top. I used 10mm open ended wrench for flange nut, 10mm socket wrench for 2 bolts on upper connection, 1 bolt screw on middle connection, 24mm socket with long handle for banjo, bottom connection. Used turkey baster to which I attached long straw with clear box tape to drain reservoir and quart plastic milk container for old fluid. Also used alum baking pan for oil drain pan below banjo nut. Of course plenty of paper towels for excess oil on hose. Emptied reservoir first using improvised turkey baster. Disconnected top flange first, other 2 holding bolts at top, pulled out sensor plug, pulled back and after cleaning upper hose under insulation( leaking fluid) ,disconnected center screw(center bracket) and then went for the banjo nut after jacking car up with Nissan jack and using standard jack stand on right side. Once removed tire able to reach banjo behind wheel well with 24mm socket and long handle. Be sure to place oil pan under the banjo nut. Your hands will get dirty and fluid will leak after you place hose on ground.(use paper or something else under hose). Once disconnected took my hose to Pirtek, a national firm that repairs hydraulic hoses. They can do if metal ends are not damaged. Their website is http://www.pirtekusa.com/. If in Southern Cali and near Commerce can talk to Mgr. Ramiro Galvez. Cost about 48 bucks and repaired in about 30 minutes in-house. Cannot do from mobile truck. Very clean shop with friendly, knowledgeable staff. Say they do all the time because of cost or replacement hoses(see forum). Hose is better than original because braided on outside and steel braided on inside. I suspect other nationwide shops are the same. Very pleased with work and cost. Putting back on by loosely attaching upper bracket bolts then drooping hose in position, lining up lower banjo bolt and screwing in(hard), then loosening upper bracket bolts, folding back top part of hose then connecting center bracket screw(I used tie wraps), then reconnecting upper bracket bolts, flange nut and sensor plug. Fill reservoir to cold max, turn car on and turn wheel from stop to stop slowly several times and check reservoir. B sure to fill to cold max. Be sure to check for leaks esp. at banjo before replacing tire and lowering car. Heard some noise(air in system) Local master mechanic sez takes about 500 miles to work out whenever change pump or hose. Good Luck and try to repair if you can. U'll save bucks.
There are three reasons why you would hear a whine in powersteering. The first reason is when the steering wheel is turned tofar. The fluid flow to the pump is cut off forcing… the pump intopressure relief. The pump has to recirculate the high pressurefluid within itself because there is nowhere for this fluid to go.If this is done to long then the fluid can heat up causing thefluid to break down and causing parts inside the pump to experiencemetal-to-metal contact. A second reason why whining could occur isbecause of an increase in the pump speed. The more fluid that isforced through the ports at a time can causes a velocity and thefluid cannot move fast enough. The vanes inside the pump cause avacuum, which will fill with oil vapor immediately. When the vanereaches the high pressure port a vacuum cell is opened and oilrushes in to fill the void. The third reason when the oil in thereservoir really gets churned up or is low. This will allow abubble into the pump.
To replace power steering fluid on a 95 Geo Metro, open the hood. There is a large yellow knob labeled with powering steering fluid only. Drain the old power steering flui…d and place new fluid.
This is your power steering pump failing, I would suggest replacing it sooner rather than later.
I am no expert, but how many miles are on the vehicle? I have found on the internet that there is a bulletin out for 2001 Dodges concerning power steering. If your p/s unit ha…s a whining noise it may be caused by a partially clogged reservoir. In addition, since 2001, Dodge recommends automatic transmission fluid instead of p/s fluid. I confirmed this with 2 Dodge dealerships and with the owner's manual. I had my car's fluid changed and the garage put in p/s fluid, in hopes that the groaning noise would disappear. it didn't and that is when I discovered on-line that ATF should be used instead and that replacing both the fluid and reservoir should solve the problem. On-line a person replaced the pump and then the rack. No change. He replaced the reservoir and the noise went away. Rob
Begin by loosening the tensioner pulley on the front of your 1996 Nissan Maxima engine. Slide the tensioner pulley to the right. The old power steering belt will become lo…ose and can be removed. Put the new power steering belt on. Tighten the power steering belt by sliding the tensioner pulley to the left.
First check that theer is enough power steering fluid in it, if that doesn't solve the problem then it needs reapir or replacement when it gets worse.
Trun your steering wheel to full lock left and right and hold it in full lock (One side at a time) for about 10 seconds if it is the steering pump that is whicning the w…hine sound will change when in full lock.
um that is hard to say
IF ITS NOT LOW ON FLUID THEN THE PUMP NEEDS TO BE REPLACED. IF ITS NOT LOW ON FLUID THEN THE PUMP NEEDS TO BE REPLACED.
* Disconnect the negative battery cable * Loosen the tensioner and remove the drivebelt * Using a large syringe or suction gun suck as much fluid out of the power st…eering fluid reservoir as possible.Place a drain pan under the vehicle to catch any fluid that spills out when the hoses are disconnected * Loosen the right front wheel lug nuts,raise the front of the car and support it securely on jackstands and remove the wheel * Working under the car remove the pressure line to pump banjo bolt then detach the line from the pump.Remove and discard the copper sealing washers.They must be replaced when installing the pump.Wrap a plastic bag around the end of the hose to prevent fluid spillage * Loosen the clamp and disconnect the fluid return hose from the pump and plug the hose * Detach the right tie-rod end from the steering knuckle arm and swing the tie-rod to the rear out of the way * Remove the pump mounting bolts then guide the pump out through the fenderwell
Check the fluid level; if ok is there any chance someone could have topped it off with brake fluid? (You can substitute Dexron transmission fluid but brake fluid is a WHOLE d…ifferent critter). Or it could just be wearing out.
It probably needs power steering fluid added.
Your power steering is low on fluid .. Top it up
Check the belt tension. it is too hard on the bearing or it's running dry.
One source of whining could be many things but the first that comes to my mind is the Alternator. The CV joints could possibly make this noise too but I would personally consu…lt a mechanic about this. any motor attached to the engine could be a cause but I would take it to a mechanic: alternator, compressor, water pump, etc.
