you wont need any special tools to service the bearings, an old can of cerelac or coffee some gasoline or acetone to wash them and some grease to pack them.

Your autozone/orielly/aap have a bearing press assortment for rent (basically free) which makes the job a breeze, you only need to buy a brass punch to remove the races

In your car the wheel bearings are packed anytime the brake disc requires change as the disc is inboard.
