Rear Wheel bearing Endplay

Hi Packard people

I am busy fixing up my rear brakes and in the process had to remove the backing plates. The bearings seem fine, but I am replacing the oil seals.

My problem: how to set the bearing end play? With the new seals and the shims installed there is excessive in and out movement of the drive shaft - I would guess about 1 mm. Not the .004" -.007" specified. As I understand it this is set by removing or adding shims between the backing plate and the flange of the diff? In my case even if removing all the shims this play does not seem to get less? Will putting on the drum have any effect?

I really do not understand how the end play is set here. My biggest fear is that the bearing is not 100% correct as it seems to have been replaced previously. If the inner race is too thin can this be causing my problem? Can someone with a loose original bearing measure it for me?

Thanks a lot as always.

Regards
Barrie
