Front shock absorbers were both leaking heavily. These were replaced in 09/2013 and 10/2012 previously. No, I don't offroad my Marquis. It just eats shocks for some reason. The shift indicator cable broke. When shifting into Park, it suddenly was reading Rark. And Neverse, Deutral and 2rive. After a week, the cable fully broke so it showed "1" all the time. I know my car is #1 all the time!
