The fifth gear grind is pretty common. Mine does it if I am tached up high when going into fifth. I am not sure if you know about evolutionm.net? A lot of Evo owners are on there with the same problem. I have heard that in some cases it is worse after the dealer "fixes" it. I bought mine used and the fifth gear syncro had already been replaced and a new transfer case put in all in less then 13k miles.
What I found to help avoid the fifth gear grind is to shift lazely into fifth and it won't grind. What I mean is take it out of fourth and then just kinda let it fall into fifth instead of pushing it in. Good luck with getting it fixed though.
