Question... I was changing out my struts. On the driver side as I was positioning the strut a leak started where the axle connects to the ___? Brown fluid. once I positioned the strut and aligned the bolt holes the leak stopped. Probably a half quart of fluid on the floor. Question is what fluid do i need to top off and where? Also why would the leak stop?? Did the seal not break? Thoughts? 2008 AWD ford edge SEL.
