And in the pic above, Im gonna say the top one is the drivers side and the lower is the passenger. If you look at the half shaft, it as well has the half spline. The smooth part is where the seal rides. So half spline for the half shaft (right) and half spline for the pass (left).
what he said..

and to the genius who says abs and non abs are waayy different axles theyre not that different.. the difference is a small ring on the outer part of the axle that the abs wheel speed sensor reads of of, a non abs axle will work in an abs car, it will just throw an abs light..

i personally buy all my axles from bumper to bumper.. and i always ask for NEW axles, not reman..
