Low tone of horn sound can be heard while I drive at times regardless of speed. It seems like the sound disappeared after I add more power steering oil. But the moaning sound returns in a few months.
Over time trash and debris builds up in this system from wear of parts of the system. There is a screen in the bottom of the fluid reservoir that clogs with this debris. When this occurs the power steering pump is "starved" for fluid and makes a whining noise when turning the wheels especially at low speeds. Replacing the pump will not fix this problem. To fix this problem I bought a new reservoir (about 25 bucks) and replaced the old one. Before I installed the new reservoir I completely flushed all of the old fluid and debris out of the system. I have 220000 miles on my van now and still using that orginal power steering pump.
Replaced power steering pump, but still makes the noise
moaning or loud noises occur when I turn the vehicle - haven't had it repaired but may need a new power steering reservoir, the steering rack is leaking on rt side.
We had the same moaning noise and had the stearing replaced for around 760.00 but two years later the same noise is back. Not sure what to do now.
moaning/grinding noise when turning steering wheel at slow speed
fog horn/moan rack leaking
Moaning noise when turning at low speeds. Did not hear this at high speeds. Thunking noise sometimes heard on tight turns and no response when turning. Mechanic will be replacing just the Rack, not the Pinion for $760.00. Will see if this fixes the issue.
