What should the torque be on the hub nut? I read through my shop manual but found it a bit confusing. Previously I had tightened them on there pretty good and haven't seemed to have any issues yet but I want to make sure I'm not causing any damage.
Thanks,
Pete

Re: Torque Spec on Hub Nut?
Step 1. Torque the hub nut to 14.5 ft.lbs while rotating the hub forward and backwards 5 times each.
Step 2. Loosen the nut and re-torque to 5 ft.lb.
Step 3. Back the nut off by 30 degrees. To do this take a look at the nut. There are 6 flat sides and 6 corners. Pick any corner and rotate it backwards (or loosen the nut) to put that corner where the center of the flat that precedes was. So in other words the center of the flat is 30 degrees from the corner.
Step 4. Take a punch or a castle nut locking tool and lock the nut in place.
You should have new castle nuts when you do this too.
Hope this helps!
