The front wheel bearings on a 2wd are different than a 4wd. The hub is basically part of the brake rotor. The rotor will have an inner and outer wheel bearing and an inner wheel seal.
They are much easier to replace than an entire hub assembly.
If you look at the pictures below, I attached the directions for replacing wheel bearings. Make sure the new bearings are properly greased.
I hope this helps. Let me know if you have other questions.
See pics below.
