Manual says 104 ft/lb, I got to 70 and my "feel" said more could mean trouble? Anyone bother to try this
Were you able to finger-spin the nut all the way to the point where it bottomed out before you started torquing it? If not, then you probably have some "running torque" value that you need to add to the 70 you used. Torque specs are for clean, dry threads; any contaminants will skew the values.
Thx Yoss. Everything clean and I always put a light coat of grease on the axle bolt and threads. Have you torqued yours 104?
If you use any kind of grease on the nut you need to reduce the torque value (about 20% for regular mineral oil based grease). If you use anti seize on the threads you need to significantly reduce the torque value (possibly as much as 40% depending on the type of anti seize used). In you're case if you are using regular grease with out a friction modifier like moly or teflon then 70-80 ft. lbs. sounds about right.
I'd worry less about that nut loosening or falling off and more about being able to get it off with the tools you carry. My foot is my torque wrench on that nut.
