Hph, see KPack’s project blog (page 64, post 633) for a file that covers many of the details of servicing the rear axle.

See: Re: KPack [Project Blogs] - Packard Motor Car Information (packardinfo.com)

Additions to the supplement that were identified during Kevin’s project were:

1. A note to lubricate the inner seal with gear oil, especially if a new seal is being installed.
2. A note to lubricate the outer seal with either gear oil or bearing grease, especially if a new seal is being installed.
3. A note on the addition of a series of center punch marks if a loose fit is encountered between the outer bearing race and the axle housing bore.

The pinion seal may be replaced in situ. The key element is returning the pinion bearing preload back to the level is was prior to the seal replacement, while is done by placing the pinion nut in the same position, relative to the pinion gear, at the conclusion of the procedure.
