Diagnosis needed
On a cold start on a cold (around freezing or less) morning, the power
steering makes a moaning noise. The power steering fluid seems frothy. After a few minutes of driving the noise goes away. I see no evidence of a fluid leak. Could air be getting into the system that is forced out as I drive and as everything warms up? I added quite a bit of Lucas PS additive a few days ago. Hasn't made a difference. |

How low was it when you added the additive?
In any event, if it keeps up, either ignore the noise, or expect to be spending some money to replace the PS Pump (If you are lucky.)

Top posting because you did?
I said I added it a few days ago. I don't want to destroy the rack avoiding replacing the pump. OEM pumps are expensive, but 3rd party ones aren't.

The things you don't think of. After 219,000 miles, I should think about
replacing the p/s fluid. Thanks, folks! Ken Chuck wrote: > It might be that the cold temperature is causing the pressure relief > valve to open, and you are hearing the valve buzzing.

With 200k + Miles, I'd sort of expect the wear on the pump to be enough that
a new one is in your future, or you just wait until the power steering becomes "weak", and then replace the pump. With new fluid and warmer weather, you may find that the effectivity of power steering is not what it should be, due to pump wear and fluid without all the stuff that accumulated over the years.
