Spindle Nut Torque Spec
Hey Guys,
I wanted to know if anyone knew the torque specs for the spindle nut. The bolt that holds the front end brake rotors and bearings in place. The car is a 1990 Mustang LX. Thanks.

These nuts only need to be tightened enough to get the cottern pin in place... Something like 12 ft lbs.
If you had SN-95 spindles with hubs that have internal bearings, the torque spec is around 200 ft lbs. (180? or 220?, don't care to remember such things)

FWIW
If you've remove the wheel bearing and are tightening the spindle nut this is what Ford Shop Manual say to do.
If the wheel is excessively loose on the spindle or does not rotate freely, adjust the front wheel bearings as follows:
1. Raise vehicle on a hoist until tire clears the floor. Refer to «Section 00-02».
2. Remove wheel cover. Remove grease cap from hub.
3. Wipe excess grease from the end of the spindle. Remove the cotter pin and nut retainer. Discard cotter pin.
4. Loosen adjusting nut three turns. Rock wheel, hub, and rotor assembly in and out several times to push the shoe and linings away from the rotor.
5. While rotating the wheel, hub, and rotor assembly in a counterclockwise direction, tighten the adjusting nut to 23-34 N-m (17-25 lb-ft) to seat the bearings.
6. Loosen the adjusting nut one-half turn, then re tighten to 1.1-3.2 N-m (10-28 lb-in), using an in-lb torque wrench
7. Place the nut retainer on the adjusting nut, so the castellation on the retainer are in-line with the cotter pin hole in the spindle.
8. Install a new cotter pin, and bend the ends around the castellated flange of the nut retainer.
9. Check front wheel rotation. If the wheel rotates properly, install the grease cap and wheel cover. If rotation is noisy or rough, follow procedures outlined under Replacement and Lubrication.
10. Before driving the vehicle, pump the brake pedal several times to restore normal brake pedal travel.
