P/S noise/moan/vibration

The P/S on my 2008 a moaning noise in cold weather but does not in warm weather. I have checked the fluid for level and foaming but everything looks normal. I question if it may be a harmonic but can't figure what would cause in in temps below 50 degrees and not above that temp. Even after 40 miles in cool weather it sound like it has low or burned fluid yet is normal in warmer temps from start up to key off. Any ideas?

Time to change fluid. Power steering fluid or ATF in your case will break down over time and require flushing the system now and then. As for the older 24V's its every 30K miles. As for getting it done check out AH64ID article. http://articles.mopar1973man.com/3rd-generation-dodge-cummins/53-engine-system/119-power-steering-flush

Synthetics are not required. I can get down to -25 to -30*F during the winter with standard petroleum Power steering fluid without a issue. Don't let the synthetic go to your head thinking it goes farther. Make sure you still change the power steering fluid ever 30K miles because the power steering system doesn't have a filter in it so if there is debris it will be pump through the system like it out not.
