Front wheel bearing/hub replace question

Seems pretty straight forward, but 1 question:

Will any diff lube come out when I remove the old bearing/hub? Or is there an inner seal that will prevent this from happening?

Basically just checking if I should pull the diff lube before the bearing in order to prevent a mess.

Thanks

Yuppers, nothing will come out. Just make sure those hubs are tight!!!! It calls for 170 ft lbs. I would suggest to get no less than 160! I did the old school way of snugging down but I lost more hubs than I care to remember that way. TIGHT TIGHT TIGHT!!!!

Best way is a long bar on the axle nut and have someone hold the hub with a screwdriver on the studs (protected by a lug nut of course). Really crank down because front hubs are expensive and a bad one leads to eraser style tire wear!

Get a real torque wrench. You should be using it on your lug nuts and other repair work anyways.
The spec is 175, even 10ftlbs +/- will lead to premature failure.

'97 zj 5.2, some stuff, some other suff, and some things that even work sometimes.
