Recently when i dumped 0w20 in my PS system, I turned the steering lock to lock with both wheels off the ground to push out the old fluid and it made a big fuss with binding noises and an occasional clunk that sounded like it was coming from the tops of the struts. Plenty of resistance too. Any way to free these things up or do i just need to put new quick struts in the car? 2005 Chrysler Minivan
