oOo QUESTION ABOUT 500SEL STEERING WHEEL oOO

[Mercedes_NY]

HI GUYS ... SOMETIMES DURING DRIVING THE STEERING WHEEL OF MY 92' 500SEL GETS CLEARLY TOUGH ( NEEDS SOME FORCE TO TURN IT ) ... I CHECKED THE STEERING FLUID AND IT WAS OK ... AFTER CAR IS SHUT OFF AND PARKED FOR AN HOUR OR SO, SUDDENLY EVERYTHING DISAPPEARS AS IF THERE WAS NO PROBLEM BEFORE ... THIS HAPPENS FROM TIME TO TIME ... LIKE ONCE A WEEK OR SO ... ANY SUGGESTIONS ..? THANKS IN ADVANCE

I think they had speed sensitve steering on that model, I think it controlled fluid flow.
Maybe someone else can add info to it!
