Axle Splines a Little Rough??

I bought the SG off of ebay and said it was newly rebuilt. I have only put about 700 miles on the car since putting the 8 3/4 in. I'm pretty sure the axles were in decent shape when i put them in. The pics of the axle are from the right side/passenger side with the adjuster nut, but both axles are similarilly kinda rough. The first four pictures are of the drivers side which seems to be worse than the passenger side. Its almost as if the inner spline is of better quality that the outer within the diff, and i can feel a definite difference running my finger from the rough outside spline to the smooth inside spline.
I may just have to take it to a driveline shop, i suppose. I was just hoping to change the crown and pinion from 3.23 to 3.73 myself and slide the axles back in, but may have to spend a bit of inspection dough.
