Agreed.
We just did the axles in my 96 EX, and they definitely take a little "encouragement." You'll definitely know when they go in. I was pretty freaked out watching the guy that was helping me when he popped the first one in back when we did the tranny. I thought he was going to snap the axle before it was even in, but it definitely takes a pretty good shove to get them in.
Highmile is right too -- make sure you do the tranny side of the axle first.
