Hi Grant,
The Dana Spicer Dana 44 Ultimate JK Front Axle Assemble with 4.88 Ratio is ready to bolt in once you swap over the steering knuckles and brakes. So no it does not come with new wheel bearings.
This axle also has a built in electronic locker which may need some wiring work to get functioning.
If you have any further questions contact our customer service center @ 877-474-4821 and they can help you.
