Eaton HO52/72 hub questions

[2500dmaxlv]

Hello Everyone,

I'm a new member to the site and am building a 1980 Chevy K5 with a Dana 44 front axle and a Eaton HO72 rear axle. I'm working on the rear axle now and have a couple questions that maybe some of you could answer.

Should I pack the wheel bearings in the rear axle? I have seen this done on a couple other threads, but wouldn't the bearings get properly lubed by the diff oil?

What are the torque specs for the inner and outer spindle nuts? I found one thread on here and it said to torque the inner nut to 30-40 ft lbs then back it off to align the keyway. What about the torque for the jam nut?

Thanks for your help!!
