Seals are considered wear items, and they are hard to remove without damage, hence the procedure for replacing the seals.

If you can remove them wthout damage, as GermanMarque suggested, and they aren't terribly worn, then more power to you and go ahead and reuse the seals.

As for the rest of the procedure, follow the Haynes manual to the letter. Take no shortcuts. Bearings are unforgiving if you do anything less than a perfect job. Post back if you have any more questions or if you don't understand something.
