I'm not familiar with that particular vehicle, but any small 4WD vehicle will have CV axles for the front, which means that the wheel bearings are pretty similar to any other car with the same sort of drivetrain.
Mostly, it depends on how the races are. If the bearing races are shot (likely), it requires a bearing puller and installation tool, and possibly a torch (propane should be fine).
If you've done a lot of car work before, it's a stinky, annoying pain, but not really that difficult. If not, pay someone to do it.
