moan/fog horn sound not only while turning but while in park when van first start up. Have not fix problem trying to get the right answer.
Moaning, vibrating noise heard/felt when turning the steering wheel at slow speeds.
Replaced steering pump reservoir, which seemed to help, somewhat.
I fixed the problem by simply adding power steering fluid to the reservoir approximately 3/8" over the max fill line. The noise is gone completely. Try this before replacing anything.
Got the same problem. I saw somewhere that it may be just a filter in the power steering oil reseervoir. Looks like cleaning or replacing this filter would eliminate the noise.
while pulling out from a parking space, during right turns. a monaing or grumpling sound can be herd.
