Me and Hotstartup changed my Differential Fluid tonight. also my oil and coolant. I took some pics of the differential fluid change for you guys. its pretty easy to do..
jack up the car...remove the passenger side front wheel, remove the lower plastic shield under the front of the car
the green circle is the drain plug, the red circle is the fill plug.
take out the differential fluid drain plug...
drain old fluid out (mine was really dark and dirty)...clean area and plug...put back in drain plug.....remove fill plug...
fill differential fluid back up. we used a hose because the fill hole is hard to get to. see the pics below.
put back in the plug..and you're done! One 1.1L bottle of fluid is all you need. we used Quaker State brand.
