Power steering
Had a whining noise from the pump..put new pump on put fluid in and still no power steering..but no more whining noise from the pump.
My car has 180000 miles.
My car has an automatic transmission.
Experienced mechanics share their insights in answering this question :
Hello, the whining noise the old pump had is aeration usually from low fluid level that will damage the pump, that means there is a leak of fluid. This system is a closed type system no leaks allowed. First check the condition of the hoses, should be clean, dry and no visible cracks. You need to check the output of the new pump, if that’s good. Next step would be an issue with the steering rack itself. If you’d like, a certified Your Mechanic Technician can come to your location and check the pump and steering assembly.

power steering fluid is leaking
ANSWER : With a power steering fluid leak that big, you certainly should have the vehicle inspected as soon as possible to find the exact cause. Any of the components you listed can be the source of the leak. The power steering pump as well as the rack & pinion steering unit rely on the fluid for lubrication as well as cooling. The whining you hear is from the pump when the fluid runs low or empty. Your issue can be caused by something as simple as a fluid hose right now, but continued ’running dry" of the power steering fluid, can result in damage to both the pump and the rack & pinion unit. If that happens, you can take what may be a repair of a few hundred dollars and turn it into a repair of a couple of thousand dollars.

ANSWER : This suggests that you may have a leak somewhere else in your power steering system such as one of the hoses or the rack and pinion system. As you may know, the power steering system is a highly pressurized system that can have as much as 300+psi of pressure in the system at times, so it is not uncommon for these types of leaks to happen. If you’d like to get this fixed, I would recommend having an expert from YourMechanic come to your location to diagnose the leak in your power steering system and make the the necessary repairs to fix it.

Chrysler 3.8 L. T&C power steering rack and pump replacement.
ANSWER : As you may know, the power steering rack pumps power steering fluid through a series of small reed valves that help to produce hydraulic pressure as the system is pressurized by the pump. This is what allows the power steering system to assist you in steering your car. When either the pump or the rack is not working properly, one or the other can sometimes over compensate for the other to a certain degree, but will eventually be overworked and fail. It sounds like this may have been the case in your situation. I would suggest having a second opinion on the previous mechanic’s work. If you’d like a professional from YourMechanic can come to your home or place of business to properly diagnose and repair your power steering system.

power steering problem.
ANSWER : Hello. Noise could be a sign of trapped air, low fluid level, or a mechanical fault in the pump. While the system is cold, check the fluid level. If the fluid level is OK, remove the cap and turn the steering wheel left and right to full extent while it is on. If there is air in the system, that will help purge it. Replace the cap. If the noise remains, it needs to be determined if it is coming from the pump or another accessory, pulley, or belt. YourMechanic has experts in this type of power steering diagnosis and once the fault is found, they will let you know of the cost to repair.
