1967 K20 Adjust rear wheel bearings after new seal install

[marina blue bob]

Hey Guys: Need help from anyone who has replaced rear axle seals on HO52 axle and adjusted rear wheel bearings after.
- The GM Service Manual states: torque outer lock nut to 175 ft lbs. I tried it and it just does not work. The lock ring gets distorted and worse, the bearing load it creates causes so much drag, the hub turn is way too stiff.
- I ended up torqueing the outer lock nut to 45 ft. lbs. and it all seemed ok. No wheel bearing end play. Hub turned freely. Ear of lock ring tab bent into a recess of lock nut as per manual.
- My question: have others run into this? Reluctant to think Service Manual is wrong, but 175 ft. lb torque spec for outer lock nut just does not work. (maybe a typo - shoulda been 75 ft. lbs. ??)
What have you other guys done?
Appreciate any thoughts, advice. Thanks.
