If the splines were not misaligned before they are probably gonna be so now. You are not supposed to turn it with just one axle in there. That is what causes the misalignment. You will get it back with instructions in previous post though so dont worry.
If everything is stock on your axle then there is a threaded adjuster (see pic) on the passenger side of the axle. You can try to back that of, then do the spline aligning trick. If you succed dont forget to set the axle play back to specs with the adjuster. Sorry bout my poor spelling and english.
