I bought my 2010 Escape with about 60K miles. About a year later at 90K I feel that it wallows over dips and bumps a lot more and squats a lot more under braking and acceleration vs when I bought it it felt a lot tighter. I do treat this vehicle pretty harshly and California roads suck, so I suspect I need shocks. How long do they usually last? My coworker at the parts store thinks any factory shock would be toast by 90K miles, "especially the way you drive". Should I get OEM shocks or a set of KYBs? I want to avoid Monroe because they SUCK!
