Bill;

A while back kevinpackard was embarking on the task of repacking the rear bearings on his car. I provided him a supplement to the shop manual that I’ve been working on and off for some time now. The specific posting is in the project blog section under KPack’s 1954 Panama, page 64, posting #634. See the following link;

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.

There was a discussion on all of those subjects as the blog proceeded.

I know the supplement was written for the '48-'54 automobiles, but I believe the design of the '40 is quite similar.

The hardest part of that job is the removal of the brake drums . . . after that it is pretty much routine.
