Front or rear - and how well equipped is the DIYer?
Front wheel bearings require a special socket and a large (high torque setting) torque wrench, rear wheel bearings require a puller, an angle grinder and a press.
It's not a particularly difficult job, but most DIYers lack the equipment and the experience, if it were me, I'd invest in the socket & puller and once I've pulled the axles, take them to a machine shop to have the bearings (& retainers) removed & replaced.
Please bear in mind that these are tools that you may never use again, so you need to weigh the cost (roughly $50 for the socket and maybe $90 for a decent slide hammer puller set) against the savings in labor charges.
