What is Proper Way to Torque Trailer Axle Spindle Nut
Published 10/14/2025
Question:
What is the proper torque spec for a Dexter 7k axle spindle nut? It has the EZ lube spindle if that makes any difference. Thanks in advance.

Hey Larry, below I have the entire torque process for the spindle nut of your 7k Dexter axle hub. It's not just as simple as running the nut down to a certain torque value though as it needs to allow the hub to spin.
1. After placing the hub, bearings, washers, and spindle nut back on the axle spindle in reverse order as detailed in the previous section on hub removal, rotate the hub assembly slowly while tightening the spindle nut to approximately 50 Ft. Lbs. (12" wrench or pliers with full hand force.)
2. Then loosen the spindle nut to remove the torque. Do not rotate the hub.
3. Finger tighten the nut until just snug, align the retainer to the machined flat on the spindle and press the retainer onto the nut. The retainer should snap into place. Once in place, the retainer/nut assembly should be free to move slightly.
4. If the nut is too tight, remove the retainer and back the nut off approximately one twelfth of a turn and reinstall the retainer. The nut should now be free to move slightly.
5. Reinstall grease cap.
The problem is the bearings don't work properly if the hub is too tight. It creates too much friction and causes failure. So basically you seat the hub with the initial torque and then get the setup just hand tight and everything works the way it needs to.

Thanks again Jameson! I have a 1 1/2" socket so can use a torque wrench to get to the torque value and then will back off the nut as you described.
