front wheel bearings whine

I am not a mechanic, but can usually fix things when I have to if they don't involve too many tools....How tough would it be for me to replace the front wheel bearings on a '91 century wagon by myself? I haven't been able to find any diagrams on the web to show me how complicated it will be.

The front wheel bearings in the Century are part of the hub-bearing-wheel studs assembly. You need to remove the axle nut and use a suitable puller to remove it.

Yeah those are non serviceable wheel bearings, once you take the hub out it's just a matter of replacing it with another, not to hard. You'll need T55 Torx Bits, behind the wheel studs are three bolts you'll have to remove.
