Splines are different in the REAR diff (96=26 & 98=28), the 98+ transfer case has a narrower chain (believe this was from an earlier post)
Interior wise, I believe 98 has passenger air bag.
There are probably more changes like no egr valve on the 98's but think that these are some of the basics. Oh, headlights and tail lights are different too.
