Yep. :o) I always take the axles to a local machine shop to have the old bearing and outer seal pressed out, and the new ones pressed on (at $25 per axle, it's well worth it). They grease the bearings before installing them, and then of course you grease the housing before installing the axles.Ouch! Well, I learn something every day. So they have to be packed in grease, like the front wheel bearings?
