Oh yup that's what i was thinking of.Yah - that "12-point" dingus is a retainer cap (why they couldn't just use a castellated nut, I don't know...)
Remove cotter, remove retainer, remove nut. Service bearing/shaft/whatever you're doing. Reinstall nut - torque to, I believe, 175 pound-feet (spec's on my site under Tech Archives, link in sig. All specs taken from FSMs. I just don't have all FSMs. Yet...) If your torque wrench doesn't go to 175 pound-feet, you can use never-seez on the nut threads and reduce that specified torque value by half - 87-88 pound-feet. Your torque wrench should be able to handle that neatly.
Install retainer. If the slots won't line up, tighten the nut slightly until they will. Replace cotter pin with new - never reuse a cotter pin!
Torque specifications given in service manuals are for "clean, dry" threads unless otherwise specified.Oh yup that's what i was thinking of.
Yes you were correct 175 ft-lbs.
And what's the reasoning behind reducing the value by half if your torque wrench doesn't go up to 175?
36mm leaves way too much play, 1 3/8" fit perfectly, I read tons of forum saying "highly recommend 36mm"..........no, 36mm is too big unless jeep decided to use a different size just on mine
