yes you do. remove the cover and drain the fluid. make sure it is in neutral and spin the driveshaft around until you see a 8mm bolt in the differential. take that out and then remove the cross pin (the big round metal bar that goes straight through the differential) then push the axles in (towards the middle of the car) and remove the "c clip" on each axle. (they push right off, they are not bolted in or anything) and then remove the axles. and then a little trick if you didnt know it already is use the end of the axle to remove the axle seal instead of trying to beat it out with a hammer and chisel.
hope this helps.
