Sounds like you have a 99.5 if it looks like the newer R50's, which is what I have... in general, the only things I know that typically are problems on the R50's are the struts, (mine were replaced by the dealer when I bought it) and if you have the bose 6 cd changer stereo (dunno if that was an option in the 99.5, might be a newer thing) you might have stereo issues.
re: the warn hubs.... it may have been wheeled, best way to check is get under there, have a look at the splash guard, any cross members, for scrapes, gouges, dents... the hubs simply may have also been put on to save gas.
