1955 Buick - Rear Axle Bearing Maintenance / Service?

As I'm going to be draining my rear axle assembly of contaminated lubricant (ATF contamination) anyway I'm wondering if it would be prudent to remove the axle shafts to repack the rear axle bearings and refresh the seals? Mind you there are no outward symptoms of wear. The manual refers to doing this when relining the brakes. I'm just curious if anyone does this proactively as a maintenance item? I worked at an independent repair facility through the 70's and recall servicing vehicles with greased rear bearings (with inner and outer seals) but only remember dealing with greasing them during bearing replacement.

If you don't know when it was done last, go ahead and do it.  With modern lubricants and seals you may never need to do it again.

After you have all that done drill a hole in the bottom of the torque tube in front of the rear flange, tap threads and plug with a screw...that way you can monitor any fluid in the torque tube.
