Whining/Groaning Power Steering Pump
My 1985 380SL has been sitting for a month or so, and I just had her detailed and ready for Spring here in the Bay area. She started right up, but I immediately noticed a bit of whining/groaning when turning the wheel, and it was somewhat "heavy."
I checked the PS fluid reservoir, and it was topped off, and I couldn't find any evidence of leaks anywhere.
Is the PS pump possibly failing, or could it be a blocked filter at the bottom of the reservoir?
Just wondering what else I should check before escalating this to my mechanic.
